Abstract: International audience; Natural or artificial irradiation of certain solid materials generates paramagnetic centres, free radicals, defects or ions, which are stable enough to be identified and quantified by EPR. The irradiation dose can be assessed from the intensity of the spectrum, which opens opportunities for numerous applications such as dosimetry of radiation used in radiotherapy or to sterilise food, determination of the dose received by individuals during chronic exposure or radiological accidents, or even to date archaeological samples.

Abstract: Discovered accidently during factory building construction works, the Middle Palaeolithic site of Biache-Saint-Vaast (Pas-de-Calais, France) was excavated from 1976 to 1982 by a team of Lille University directed by Alain Tuffreau. An abundant archaeological and paleontological material, including two human skulls, was there recovered from fossil alluvial deposits of the Scarpe River. In order to determine the ages of these remains, the ESR/U-series method was applied on bone and teeth. As the U-series data obtained of the main part of the analyzed tissues do not allow the use of the classical US-ESR model, the recently proposed AU-ESR model, taking into account if necessary U-leaching from some of the tissues, was used to calculate combined ESR/U-series ages for these samples. The obtained ages suggest a MIS7 attribution to the faunal remains and permit an age of ca 240 ka to be assigned for the human remains and associated archaeological material, in accordance with the stratigraphic data and the large mammal associations.

3. La datation ESR/U-Th de restes paléontologiques,un outil pour estimer le possible remaniementdes niveaux archéologiques ?

Subjects: Series (stratigraphy), Pleistocene, Geology, Dose rate, Archaeology, Earth-Surface Processes
Abstract: ESR/U-series dating of fossil teeth is a palaeodosimetric method commonly used for Middle and Late Pleistocene archaeological levels. Beyond the geochronological interest (it is often one of the few methods applicable on sites located in non-volcanic or carbonated areas) and despite the relatively important age uncertainties (usually 10-15 %, because of the high number of parameters - over 25 - considered in the age calculation process), ESR/U-series method can allow, in combination with the available stratigraphic and palaeoenvironmental data, the correlation of the studied archaeological levels to a specific marine isotopic (MIS), if the evolution of the dose rate with time since the sample burial is reasonably well described. However, for some sites the results display great age scatter ages that could simply not be explained by local variations of the dose rate for the studied level. It could indicate instead that the palaeontological record is made by several stocks of different ages or dosimetric histories mixed in the same archaeological level.

Abstract: International audience; The archaeological site of Guado San Nicola (Monteroduni, Central Italy), under excavation since 2008, is located in the Upper Volturno Valley, near the top of a fluvial terrace attributed to the Middle Pleistocene. Several anthropic levels have been recognized within a stratigraphic sequence of more than two meters in thickness, characterized by alternating gravelly and sandy fluvial layers rich in pyroclastic materials, attributable to the end of MIS 11-beginning of MIS 10, according to the obtained radiometric dates (Ar-40/Ar-39 and ESR/U-series). In this paper we discuss the chrono-stratigraphic record, the paleontological and zooarchaeological data and we provide a detailed techno-economic analysis of the lithic industry, characterized by the coexistence of handaxes and Levallois debitage. The site of Guado San Nicola represents the oldest evidence of the emergence of prepared-core technologies in the Italian Peninsula, adding new data to the debate on the Lower/Middle Palaeolithic transition in Western Europe.

Abstract: Article history:Received 6 June 2011Available online 9 February 2012Keywords:Combined U-series/ESR dating methodFossil teethFuente Nueva-3Barranco LeonOrceEarly Pleistocene The combined U-series/electron spin resonance (ESR) dating method was applied to nine teeth from twoEarly Pleistocene archaeological sites located in the Orce area (Guadix-Baza Basin, Southern Spain): FuenteNueva-3 (FN-3) and Barranco Leon (BL). The combination of biostratigraphy and magnetostratigraphy placesboth sites between the Olduvai and Jaramillo subchrons (1.78–1.07 Ma).Our results highlight the difﬁculty of dating such old sites and point out the limits of the combined U-series/ESR dating method based on the US model. We identiﬁed several sources of uncertainties that may lead toinaccurate age estimates. Seven samples could not be dated because the dental tissues had ( 230 Th/ 234 U) ac-tivity ratios higher than equilibrium, indicating that uranium had probably leached from these tissues. It washowever possible to calculate numerical estimates for two of the teeth, both from FN-3. One yielded a MiddlePleistocene age that seems to be strongly underestimated; the other provided an age of 1.19±0.21 Ma, inagreement with data obtained from independent methods. The latter result gives encouragement thatthere are samples that can be used for routine dating of old sites.© 2012 University of Washington. Published by Elsevier Inc. All rights reserved.

Abstract: The palaeontological site of Venta Micena (Orce, Andalusia, Spain) lies in the eastern sector of the Guadix–Baza basin, one of the best documented areas in Europe for Plio-Pleistocene biostratigraphy. The combination of biochronological and palaeomagnetic results, combined with the radiometric data obtained for Atapuerca Sima del Elefante, indicated that the Venta Micena stratum was formed between the Jaramillo and Olduvai palaeomagnetic events, most likely between 1.22 and 1.77 Ma. Five fossil teeth from two outcrops (sites A and B) were selected to assess the potential of combined uranium series–electron spin resonance (US-ESR) dating of Early Pleistocene sites. Although the US-ESR results of the first outcrop showed a large scatter between the three teeth, the mean age of 1.37 ± 0.24 Ma can be considered a reasonable age estimate for Venta Micena. The mean ESR age of 0.62 ± 0.03 Ma obtained for site B seems to be a severe underestimation when compared with the independent age control. This underestimation is attributed to a relative recent U-mobilization event that led to some U-leaching. The results show that any ESR age calculations of old samples are extremely sensitive to variations in the measured 230Th/234U ratios in dental tissues. Although the results demonstrate that ESR can in principle be applied to Early Pleistocene sites, they also reveal the complexity of dating such old teeth. It is necessary to continue research in several directions, such as study of the behaviour of ESR signals in old teeth and understanding recent U-mobilization processes, to improve the reliability of the combined US-ESR dating method applied to Early Pleistocene times, a period for which the number of available numerical dating techniques is very limited.

Abstract: The Dali skull is a key fossil for understanding human evolution in China. It has been attributed either to an archaic Homo sapiens , an evolved Homo erectus or to other species of Homo , such as Homo heidelbergensis . The cranium was discovered in 1978 in Shaanxi Province in a fluvial terrace which was recovered by a loessic sequence including two interglacial palaeosoils. ESR/U-series data analyses were carried out on several teeth recovered from the palaeoanthropological level. Four samples exhibit different kinds of uranium-uptake behaviour, but the results seem to indicate that the cranium is coeval with Marine Isotope Stage (MIS) 8 and that some teeth might be reworked from older deposits.

Abstract: The Mauer mandible, holotype of Homo heidelbergensis , was found in 1907 in fluvial sands deposited by the Neckar River 10 km southeast of Heidelberg, Germany. The fossil is an important key to understanding early human occupation of Europe north of the Alps. Given the associated mammal fauna and the geological context, the find layer has been placed in the early Middle Pleistocene, but confirmatory chronometric evidence has hitherto been missing. Here we show that two independent techniques, the combined electron spin resonance/U-series method used with mammal teeth and infrared radiofluorescence applied to sand grains, date the type-site of Homo heidelbergensis at Mauer to 609 ± 40 ka. This result demonstrates that the mandible is the oldest hominin fossil reported to date from central and northern Europe and raises questions concerning the phyletic relationship of Homo heidelbergensis to more ancient populations documented from southern Europe and in Africa. We address the paleoanthropological significance of the Mauer jaw in light of this dating evidence.

Abstract: Geochemical alteration processes in archaeological sites may affect the environmental dose rate during the burial history and cause inaccuracy in age determination by palaeodosimetric dating methods, such as luminescence or ESR. In Arago Cave (Tautavel, France), the original composition of the sandy aeolian sediments of palaeoanthropological level G, where the Homo heidelbergensis Arago XXI skull was found, has been modified by both carbonation and phosphatization processes. Eight fossil teeth were collected from different geochemically affected parts of level G and analyzed by the ESR–U-series method. All the teeth are presumably contemporaneous. The results show that the samples from the phosphated area agree within error with those from the carbonated area. Surprisingly, the samples from the non-altered area show ages 100–150 ka younger. This difference is mainly due to the remarkable changes in the gamma dose rate over time. The measured in situ dose rate accounts for more than 50% of the total dose rate for all the samples. We observed that the samples' equivalent dose ( D E ) were generally 20% lower in the non-altered area than in the carbonated and phosphated ones. These results show the crucial effect of the geochemical processes affecting the age calculation by ESR–U-series method in comparison with independent chronological data.

Abstract: In ESR dating of tooth enamel, a single saturating exponential (SSE) function is generally used to fit the dose response data points. This study shows several analytical and physical limits of this function when applied on Lower Pleistocene samples with expected ages in excess of one million years. We have checked other mathematical functions to obtain a closer fit to the analytical data. Indeed, the choice of the fitting function becomes crucial as this has a strong influence on the DE value. Among the functions used, the combination of a double saturating exponential (DSE) function provided the best approximation to the experimental points. The use of just one SSE function seems to lead to DE systematic overestimations if the DE values are >300 Gy.

Abstract: Resume La recherche des indices de la presence de premiers peuplements humains en region Centre a ete menee dans les formations alluviales du bassin de la Loire moyenne. Elle a permis d’inventorier et de caracteriser les alluvions deposees lors des cycles glaciaire–interglaciaire successifs du Pleistocene inferieur et moyen, dans quatre vallees affluentes de la Loire : la Creuse, l’Indre, le Cher et le Loir. Ces formations ont ete datees systematiquement par la methode de resonance de spin electronique appliquee aux quartz fluviatiles. Parmi ces indices, cinq sites prehistoriques a industries du Tres-Ancien Paleolithique associes a des nappes du Pleistocene inferieur, et neuf sites a bifaces du Paleolithique ancien inclus dans des formations du Pleistocene moyen sont presentes dans cet article. Le centre geographique de la France (47° N) aurait ete atteint par deux vagues de peuplement nettement separees dans le temps par une periode d’environ 400 ka au cours de laquelle d’importantes pejorations climatiques se sont produites, notamment a la fin du Pleistocene inferieur. Ces deux vagues de peuplement ont produit des ensembles industriels comportant de nettes differences de comportements dans les approvisionnements en materiaux et dans les modes de debitage. Aucun lien typologique ne parait relier ces deux ensembles.

Abstract: L’inventaire des nappes alluviales fossiles conservées dans la vallée moyenne du Cher, l’un des principaux affluents de la Loire en rive gauche, a été entrepris depuis 2003. Une fois repérées, les formations alluviales ont été sondées mécaniquement jusqu’au substratum, étudiées stratigraphiquement et échantillonnées pour analyses géochronologiques par la méthode de la résonance électronique de spin (ESR) appliquée aux quartz fluviatiles optiquement blanchis. Deux secteurs ont été définis dans la moyenne vallée du Cher, de part et d’autre de Vierzon, et appelés respectivement secteurs « Berry » et « Sologne ». Dans le secteur « Berry », la vallée a une orientation N 160o et suit de grands accidents tectoniques qui mettent au contact les formations calcaires du Jurassique et les dépôts calcaires lacustres tertiaires. Dans ce secteur, l’incision totale de la vallée est de 50 m et neuf formations alluviales étagées ont été inventoriées. Elles sont généralement conservées sur la rive gauche de la vallée actuelle, dans des systèmes karstiques et sur des blocs basculés ou abaissés. Trois de ces formations ont été particulièrement étudiées et datées. Dans le secteur « Sologne », la vallée suit un axe synclinal orienté est-ouest. Elle traverse les formations crétacées, puis les sables burdigaliens, et son incision passe d’amont en aval de 35 m à 20 m seulement. Dans ce secteur, quatre ou cinq nappes alluviales ont été individualisées selon les sous-secteurs. Pour les plus hautes d’entre elles, les différences d’altitudes relatives sont très faibles, ce qui complique l’étude. Par ailleurs, les nappes moyennes sont mal conservées. La datation des nappes de la vallée moyenne du Cher par ESR est en cours. Les premiers résultats indiquent que la mise en place de la vallée du Cher a débuté dès le Pléistocène inférieur. Les industries du Très-Ancien Paléolithique du site de Lunery (Cher), dont la situation a pu être précisée par des fouilles, sont ainsi datées de 1,1 Ma, en accord avec les données biochronologiques obtenues sur le site voisin de Rosières, et confirment la présence de l’Homme dès cette époque dans le bassin de la Loire moyenne. Par ailleurs, les âges obtenus sur les nappes moyennes, s’ils sont confirmés, indiqueraient que les industries à bifaces étaient déjà présentes dans cette zone et très développées il y a 700 ka. Since 2003, field surveys in the Middle Cher River Valley, a left tributary of the Loire River, have allowed the inventory of the Pleistocene alluvial formations. Most of them have been mechanically bored as far as the substratum, stratigraphically studied and sampled for Electronic Spin Resonance (ESR) geochronological analyses. Two different sectors, called respectively “Berry” and “Sologne”, have been defined upstream and downstream of Vierzon. In the “Berry” Sector, the river flow N. 160o along a major tectonic accident which cuts Jurassic limestones and Tertiary lacustrine calcareous deposits. The incision of the valley is about 50 m and nine Pleistocene alluvial formations have been recognized on the left side of the modern valley only. The deposits are often preserved in karstic systems or on tilted down blocks. In the “Sologne” Sector, the river flows along an east-west syncline through the Cretaceous chalky and clayeous formations and the Burdigalian sands. In this sector, the incision, about 35 m upstream, reduces to 20 m downstream and four or five alluvial formations have been studied. Differences between the relative altitudes of the highest terraces are very small. The middle sheets are rarely preserved and the lower formations spread out the two kilometres wide alluvial plain.The dating of the different sheets by the ESR method applied to optically bleached fluvial quartz is in progress. First results indicate that the present Cher Valley began its incision during the Lower Pleistocene, in spite of a low incision referred to the other main tributary valleys of the Middle Loire Basin. The Early Lower Palaeolithic artifacts founded by excavations in the alluvial deposits of the Lunery site (Cher) have been dated about 1.1 Ma and confirm other evidences of such ancient human settlement of the Middle Loire Basin. The ESR ages obtained for the middle formations, if they will be confirmed, indicate that acheulean handaxes industries were present and developed in this area since 700 ka.

13. Angular response of alanine samples: From powder to pellet

Subjects: Physics, Reproducibility, Radiation, Nuclear magnetic resonance, Amplitude, Radical, Pellet, Pellets, Analytical chemistry, Dose profile, Irradiation, Instrumentation, Standard deviation
Abstract: Alanine radicals produced by irradiation can be observed through the ESR measurement of powder or in a pellet with an angular response. There are five main peaks in the ESR alanine spectrum. Usually, the central peak amplitude (A1) is chosen to perform dose measurements because it is the largest. Looking at the angular response it seems that the peak amplitude (A2) shows lower maximal deviation and standard deviations. The angular response exists from the first step of the process as powder through the granular form until the final compact pellet form. Results about the angular response on pure alanine powders and its evolution during the manufacturing process of homemade pellets, as well as commercial pellets from different suppliers are presented. The evolution of the angular response with time gives information about the stability of radicals. The manufacturing process of pellet also influences the stabilization of the radicals produced by irradiation; therefore pellet reproducibility. This study raises questions and makes proposals for a better approach to reduce measurement uncertainties for high and low doses measurements.

Abstract: The simulation of electron paramagnetic resonance (EPR) spectra of radicals potentially due to alanine radiolysis has been done. Combining theoretical spectra in varying proportions allows computing different alanine spectra. The small changes in specific regions of experimental spectra correspond to weak variations in the proportion of radicals. As the study of several parameters, such as ESR angular response of powder or time after irradiation, is not possible in simulated spectra, experimental analyses have been carried out for the ESR angular response dependence on grain size in various combinations, corresponding to an available external surface. The stabilization of the angular response is associated with a spatial reorganization of radicals. It seems that available surface and radical proportions are linked. Predicted values of angular response calculated from pure powders do not correspond to experimental ones. Weak changes in spectra seem to confirm that these variations may be interpreted as a transformation of one radical into another.

Abstract: The choice of the ESR signal in the dating of speleothems is still debated. Among the peaks observed in speleothem ESR spectra, the most frequently signals used for the determination of the palaeodoses are the peaks at g =2.0007 (h3 line), g =2.0040 (Broad Line) and g =2.0057 (h1 line). In order to determine the better analytical way to obtain reproducible D E values from these three ESR signals, successive additional annealing treatments ranging from 60–300 °C were performed on several samples of a stalagmitic floor from the Mousterian site of the Caverna delle Fate (Liguria, Italy), also dated by U -series between 90 and130 ka. The results confirm that D E values can be obtained from h3 and BL signals without annealing, while the h1 signal requires a thermal pre-treatment, to obtain the maximum intensity of this line. Then, on our samples, the D E values derived for the three lines are equivalent. It gives, hence, the opportunity to obtain data when the g =2.0007 line cannot be used.

Abstract: Electron spin resonance (ESR) dating on teeth has been used to determine the antiquity of the human presence in the area of Gunung Sewu (East Java, Indonesia). The Song Terus cave is one of the archaeological sites located in this area, which has yielded an important collection of fossil bones and prehistoric lithic industry. ESR dating shows that this cave belongs to a karstic system which has been in place since Middle Pleistocene. The results of coupled ESR/Uranium-series dating indicates closed system for uranium in tooth tissues yielding ages of between 216 and 392 ka for the oldest archaeological levels, confirming the possibility of finding Middle Pleistocene human occupations in such karstic sites in Java.

Abstract: International audience; The establishment of a chronology for late Middle Palaeolithic sites on the right bank of the Rhone valley in southeastern France is important for the knowledge of Neandertal dynamics and their demise in this area. The suite of dating methods that are directly applicable to fossils is limited for this period, especially around 50 ka where radiocarbon dating is beyond its technical limits. Currently applied to Middle and Lower Pleistocene periods, the use of combined ESR/U-series dating on Upper Pleistocene samples led to new issues, such as the acquisition of an age for samples yielding low equivalent doses and low uranium content in dental tissues. The gamma dose rate measurement thus plays a key role in age calculation. Beyond the discussion on methodological issues, the present study contributes to the establishment of a chronological framework that covers the Neandertal occupations between MIS 5 and MIS 3 for this area.

Abstract: Over the past two decades, the combined electron spin resonance (ESR) and U-series dating method has been widely applied to date fossil teeth for archaeological studies through the use of the US-ESR model. The obtained age, compatible with both the ESR and U-series data determined in all dental tissues and the burial environment, is more flexible and reliable than the parametric uptake ages (by early, linear or recent uptake models), for which selection was often based on the expected age of the site. In this paper, the mathematical basis of the US-ESR model is described in detail, from the U-uptake description to the calculation of accumulation dose in the sample and the US-ESR age determination. An example is used to illustrate the calculation of the US-ESR age, associated dose rates and U-uptake parameters. While the description in this paper is specific to US-ESR model and more largely combined ESR/U-series dating of fossil teeth, we expect that some of the principles can be used in other applications of U-series dating.

Abstract: The Lower Paleolithic sites of Ambrona and Torralba (Soria, Spain) are often associated with each other because of their proximity although they do not represent the same morphostratigraphic unit. Systematic and extensive excavations were conducted at these sites by an American team during the 1960s and 1980s. Recently (1989–2000), a Spanish team has reactivated the research by initiating a new interdisciplinary project. In the central sector and west of the Ambrona site a stratigraphy has been established with six units from AS1 at the base to AS6 at the surface, corresponding to fluvial–lacustrine deposits in which abundant fauna associated with Acheulian artefacts were found. The most abundant species were elephant, horse, deer and aurochs. Other species like carnivores occur in small numbers only. The lithic assemblage is relatively sparse and consists of a few bifaces, choppers and several flake tools distributed throughout levels AS1 to AS5. The fauna and the lithic industry therefore document human presence at Ambrona during the Middle Pleistocene. In order to verify the presumed antiquity of the Ambrona deposits, horse teeth sampled in levels AS1, AS2 and AS6 were analysed using combined ESR/U-series (US) methods. The samples from the lower levels (AS1 and AS2) underwent a very recent uranium uptake as indicated by the U-series dates, ranging between 5 and 18 ka. In contrast, a more conventional postmortem uranium uptake was observed in the upper level samples (AS6) in the enamel and dentine tissues, while a light U-leaching was observed in the cementum. The combined ESR/U-series dates obtained on these samples suggest a minimum age of approximately 350 ka, contemporaneous of OSI 9 or the end of OSI 11, for the Ambrona site.

Abstract: Since the 1980's, the improvement of the Electron Spin Resonance (ESR) method and its application to the dating of bleached quartz extracted from sediments currently allow to provide geochronological data on Pleistocene fluvial deposits and associated archaeological sites. The ESR dating of quartz may hence improve our knowledge on Quaternary chronostratigraphy, especially in case of azoic deposits, when classical methods can't be applied. The ESR method is based on the behaviour of aluminium-center in quartz exposed to solar light and ionizing radiations. This center can be optically bleached during the fluvial transport but, as this bleaching is incomplete, a residual dose must be determined and used for the age calculation. After a short description of the general principle of the ESR dating, the methodological basis and analytical procedures corresponding to the quartz are detailed, then the potential of the ESR method is demonstrated through the presentation of the results obtained from the study of the fluvial terraces of the Creuse and Yonne valleys (France)., Depuis les années 1980, le développement de la méthode de datation par Résonance Paramagnétique Electronique (RPE) de quartz blanchis extraits de sédiments, a permis d'obtenir de nombreux âges pour des dépôts fluviatiles fossiles et pour les sites archéologiques qu'ils contiennent. Cette méthode a ainsi permis de développer notre connaissance de la chronostratigraphie des systèmes fluviatiles pendant toute la période du Quaternaire, particulièrement dans les cas où il s'agit de dépôts azoiques, quand des méthodes plus " classiques " ne sont pas applicables La datation par RPE sur quartz est basée sur les réactions du centre aluminium du quartz face à la lumière solaire et aux rayonnements ionisants. Ce centre peut être optiquement blanchi pendant la phase de transport des grains, mais ce blanchiment est incomplet. Une dose résiduelle doit être déterminée pour pouvoir calculer l'âge de l'échantillon. Après une courte descnption de la méthode RPE, les bases méthodologiques et analytiques correspondant au cas particulier du quartz seront détaillées, puis le potentiel de cette méthode sera démontré à travers la présentation des résultats obtenus pour les vallées de la Creuse et de l'Yonne., Voinchet Pierre, Bahain Jean Jacques, Falguères Christophe, Laurent Michel, Dolo Jean Michel, Despriée Jackie, Gageonnet Robert, Chaussé Christine.

Abstract: Electron spin resonance (ESR) dating of quartz extracted from sediments may contribute to elaborate a Neogene and Quaternary chronostratigraphy, especially in the case of azoic deposits, when methods such as thermoluminescence or K/Ar cannot be applied. The ESR method is applicable for aeolian, littoral and fluvial sediments when quartz is zeroed or bleached by an optical phenomenon (photoelectric effect due mainly to UV solar rays in this case). ESR dating on bleached quartz is based on the presence of paramagnetic substituted atoms in the crystal lattice. The Al-center can be optically bleached, and its signal intensity decreases in fossil samples versus exposure to the solar light. After a long time, the ESR intensity reaches a plateau value corresponding to the electrons which cannot be “extracted” by the light energy. These electrons represent a “residual” dose which must be subtracted from the total equivalent dose in order to obtain the archaeological dose. Our kinetic study has the objectives of obtaining a new modelization and to establish a correct time of natural bleaching for using quartz sample as appropriate for dating. We have investigated samples from a fossil fluvial sand from the Creuse river terraces system (France). Our experimental bleaching curve obtained is compared with that one previously proposed by Walther and Zilles (Quat. Sci. Rev. 13 (1994) 611).

Abstract: The combination of electron spin resonance (ESR) and U-series dating approach is increasingly being used to fossil teeth from archaeological sites. A rigorous age uncertainty assessment is needed for this dating method. However, it is difficult to provide partial derivatives of the combined ESR/U-series (US) model, as required by the law of propagation of uncertainties. In this study, we developed a new age calculation MATLAB program, called USESR, using a Monte Carlo approach for estimating the age and the age uncertainty for tooth enamel. Tests have been performed with virtual samples ( n = 64). The results suggest that this Monte Carlo approach can provide reliable US-ESR age and reduced age uncertainty in comparison with those obtained by the routinely used program, DATA. The results also show that the new program has higher tolerance limits of U-series disequilibrium than the DATA program for US-ESR age calculations.

Abstract: Several Gigantopithecus faunas associated with taxonomically undetermined hominoid fossils and/or stone artifacts are known from southern China. These faunas are particularly important for the study of the evolution of humans and other mammals in Asia. However, the geochronology of the Gigantopithecus faunas remains uncertain. In order to solve this problem, a program of geochronological studies of Gigantopithecus faunas in Guangxi Province was recently initiated. Chuifeng Cave is the first studied site, which yielded 92 Gigantopithecus blacki teeth associated with numerous other mammalian fossils. We carried out combined ESR/U-series dating of fossil teeth and sediment paleomagnetic studies. Our ESR results suggest that the lower layers at this cave can be dated to 1.92 ± 0.14 Ma and the upper layers can be dated to older than 1.38 ± 0.17 Ma. Correlation of the recognized magnetozones to the geomagnetic polarity timescale was achieved by combining magnetostratigraphic, biostratigraphic and ESR data. The combined chronologies establish an Olduvai subchron (1.945–1.778 Ma) for the lowermost Chuifeng Cave sediments. We also analyzed the enamel δ13C values of the Gigantopithecus faunas. Our results show that southern China was dominated by C3 plants during the early Pleistocene and that the Gigantopithecus faunas lived in a woodland-forest ecosystem.

Abstract: A laboratory bleaching experiment was performed in order to improve the method of ESR dating of sediments. Several sedimentary, volcanic, and granitic quartz samples showed consistent bleaching response for the exposure to halogen lamps. It was found that the most sensitive signals are the Ti–H and Ti–Na centers. There was no difference observed within the samples exposed to light filtered by several color glass plates, according to the present preliminary result.

Abstract: A modern red deer bone was heated in a muffle furnace at increasing temperatures in the range 200 to 940°C. Samples were analyzed by infrared and X-ray diffraction spectrometry before measurement of the ESR signals around g =2.002 by ESR spectrometry. Each sample was irradiated by a gamma source (cobalt-60) at increasing doses in the range 100 to 10 000 Gy. γ -irradiated samples were then analyzed by ESR spectrometry in order to obtain the growth curve and to show ESR signal behavior. ESR signals of fossil bones from archaeological deposits of the Lazaret cave (Middle Pleistocene, France) were studied and colors were compared with modern samples in order to assess at which temperature these fossil bones were heated in prehistoric fireplaces.

Abstract: The Sierra de Atapuerca, northern Spain, is known from many prehistoric and palaeontological sites documenting human prehistory in Europe. Three major sites, Gran Dolina, Galeria and Sima del Elefante, range in age from the oldest hominin of Western Europe dated to 1.1 to 1.3 Ma (millions of years ago) at Sima del Elefante to c.a. 0.2 Ma on the top of the Galeria archaeological sequence. Recently, a chronology based on luminescence methods (Thermoluminescence [TL] and Infrared Stimulated Luminescence [IRSL]) applied to cave sediments was published for the Gran Dolina and Galeria sites. The authors proposed for Galeria an age of 450 ka (thousands of years ago) for the units lower GIII and GII, suggesting that the human occupation there is younger than the hominid remains of Sima de los Huesos (>530 ka) around 1 km away. In this paper, we present new results obtained by combined Electron Spin Resonance/Uranium-series (ESR/U-series) dating on 20 herbivorous teeth from different levels at the Galeria site. They are in agreement with the TL results for the upper part of the stratigraphic sequence (GIV and GIIIb), in the range of between 200 and 250 ka. But for the GIIIa to GIIb levels, the TL ages become abruptly older by 200 ka while ESR ages remain relatively constant. Finally, the TL and ESR data agree in the lowest part of the section (GIIa); both fall in the range of around 350–450 ka. Our results suggest a different interpretation for the GII, GIII and GIV units of Galeria and the upper part of Gran Dolina (TD10 and TD11) than obtained by TL. The ESR/U-series results are supported by a Bayesian analysis, which allows a better integration between stratigraphic information and radiometric data.

Abstract: The ESR/alanine system has been used for different applications, over several years, as a classical routine dosimetry service. This service is based on alanine dosimeters constituted by pellets manufactured by our laboratory, which are presented with some specifications of use and different parameters bound to the intrinsic quality of the dosimeter itself. These parameters were obtained through the strict application of a production protocol and a validation protocol created, tested and validated under a quality assurance system. Every year, one batch of photon dosimeters is produced and controlled using these protocols and the specifications associated with it are checked. Two categories of data are considered separately: physical parameters and experimental data obtained by measurement on our ESR system are given with their associated standard deviation.

Abstract: Combined ESR/U-series dating of tooth enamel using US model implies the calculation of a specific parameter p for each dental tissue to reconstruct its U-uptake history. The US model simulates this history as a continuous incorporation process without leaching, where the 238 U– 234 U– 230 Th system evolves towards secular equilibrium state. Consequently, the application of this model is restricted to the samples displaying 230 Th/ 234 U activity ratio below or close to equilibrium with maximum value of ∼1.05 for each tissue. In order to overcome this limitation, here, a new model named Accelerating Uptake (AU) model is proposed. This model describes U-uptake into dental tissue as an accelerating process by the introduction of two parameters, the initial uptake rate and the acceleration of this uptake rate. The AU model is then able to reconstruct a process combining incorporation followed by leaching, as well as continuous uptake one. With this model, the evolution of 230 Th/ 234 U activity ratio with time can reach values higher than unity, even beyond equilibrium. The AU model is useful in cases for which age estimates cannot be calculated by routine use of US model. The application of the AU model to the palaeoanthropological site of Mauer in Germany shows its potential for extending the applicability of the combined ESR/U-series dating of tooth enamel.

Abstract: 13th International Conference on Luminescence and Electron Spin Resonance Dating (LED), Nicolaus Copernicus Univ, Fac Math, Torun, POLAND, JUL 10-14, 2011; International audience; The area of Pleneuf-Val-Andre, Brittany, France, has delivered several Palaeolithic sites containing palaeontological remains, very rare into this granitic area. In order to precise the stratigraphical framework of the prehistoric human occupations of this zone, an ESR dating program was initiated in the late 1980s and different kinds of materials (mammal bones and teeth, naturally bleached quartz extracted from marine or aeolian sediments and marine mollusc shells) were then sampled for geochronological analyses. The present paper displays the main obtained results on three stratigraphically connected middle Palaeolithic sites: Piegu, Les Vallees and Nantois. The results are consistent with the regional chronostratigraphic framework and permit to suggest palaeoenvironmental reconstruction of the area and the dating of the various archaeological evidences.

Abstract: Located in Southern Italy, the Early Palaeolithic site of Isernia la Pineta has provided numerous palaeontological remains and artefacts in well-defined fluvio-lacustrine sequence. The normal magnetization of the main archaeological layer t3a and 39 Ar/ 40 Ar date of 610 ± 10 (2 σ ) ka, obtained from the immediately overlaying geological level, put the Isernia assemblage in the first part of the Middle Pleistocene. Previous ESR/U-series analyses of Isernia fossil teeth have displayed both recent U-uptake and severe underestimation of the ESR/U-series dates in comparison with the 39 Ar/ 40 Ar age. In order to identify the cause of this age underestimation, new analyses were realized in the present study on four bovid teeth directly recovered from the archaeological surface t3a. The ESR/U-series dates obtained were once again strongly underestimated, with an error weighted mean age of 435 ± 24 (1 σ ) ka. These too young dates could be associated to a change of the environmental γ-dose rate during the geological history of the Isernia site, related to the revealed recent U-uptake into the palaeontological remains of the archaeological level. If we consider that this dose rate change was coeval with a wet interglacial period and taking the 39 Ar/ 40 Ar age as geochronological reference, simulations with two dose rate steps indicate that this change could be correlated with marine isotopic stage 7 (MIS 7).

Abstract: International audience; During the last two decades, extensive road-construction works in Northern France have allowed the discovery of numerous Middle Palaeolithic sites. Geological and multidisciplinary studies performed on these localities allowed the establishment of a precise chronostratigraphical and biostratigraphical framework of regional significance, which could be correlated to the global marine palaeoclimatic scale. Each human occupation layer has been linked to this regional framework, thus providing a stratigraphical age-control for the Middle Palaeolithic human settlements of this area.At the same time, a program of geochronological studies was developed using TL, OSL, U-series, ESR and, as often as possible, ESR/U-series methods. Hence, bones and teeth recovered from archaeological sites of Savy, Ault, Caours, Gentelles and La Celle-sur-Seine, were analyzed and the results compared to the chronostratigraphical ages. The age results are generally in good agreement with the geological data while bones and dental tissues display in some cases U-series ages higher that the EU-ESR ones, suggesting U-loss phenomena.

Abstract: International audience; For a long time, the establishment of the chronology of Acheulian settlements in Western Europe was restrained by the lack of reliable dating methods. During the Middle Pleistocene, the archaeological sites in this area are generally associated with fluvio-lacustrine and karstic contexts. The main geochronological methods (e.g. K/Ar, Ar/Ar, U-series, OSL and TL) could not be applied because of a lack of suitable material for dating, or the expected ages were beyond the upper limit of the dating technique. For several years, the combination of ESR and U-series data has allowed the direct dating of palaeontological remains from the entire Middle Pleistocene period. Combined ESR/U-series dating was applied to several major Acheulian sites in Spain, Italy and France. This paper presents the dating results, their implications for the chronology of the Acheulian in Western Europe as well as the methodological limits of the ESR/U-series dating method caused by the effect of weathering on the uranium uptake into the teeth.

Abstract: International audience; The site of Les Auzières 2 (Méthamis, Vaucluse) was excavated from 2001 to 2005. It yielded an original and diverse fauna, unique in southeastern France (Provence). The spectrum of large mammals comprises 14 species including hyena, horse, ibex, woolly rhinoceros, giant deer and mammoth. Lithic artifacts are rare but testify to the presence of a Mousterian industry. All of these remains derive from layers that have been dated to 60 ± 10 ka by ESR/U-series method. Les Auzières 2 is of special importance for examining the issue of human/carnivore interaction in the Pleistocene since it has yielded a large assemblage of carnivore remains, and probably represents a hyena den. The diverse fauna offers a more comprehensive picture of Upper Pleistocene biodiversity in southeastern France than that usually provided by sites with a stronger anthropogenic signal.; Fouillé de 2001 à 2005, le site des Auzières 2 (Méthamis, Vaucluse) a livré une faune unique et originale pour le Sud-Est de la France (Provence). Celle-ci est composée de 14 espèces de grands mammifères, dont l’hyène des cavernes, le cheval, le rhinocéros laineux, le mégacéros ou encore le mammouth. L’ensemble de ces vestiges provient de niveaux datés de 60 ± 10 ka par les méthodes combinées de l’ESR et des séries de l’uranium. La présence de rares artéfacts lithiques de manufacture moustérienne atteste la présence de groupes humains non loin du site. L’accès à une faune aussi variée permet d’offrir une meilleure image de la biodiversité au Pléistocène supérieur en Provence que ce que ne permettent les sites plus anthropisés. Les Auzières 2 est aussi une importante contribution à la problématique des interactions hommes/carnivores au Pléistocène.

Abstract: International audience; The Visogliano shelter, in north-eastern Italy, is an important Middle Pleistocene occupation site where human remains were found together with an archaic lithic industry, including choppers, chopping tools and a few protobifaces. It is of utmost importance to try to document this period, when a second wave of settlement colonised Western Europe, carrying new flaking techniques and tools.Combined ESR/U-series analyses, integrated with biostratigraphical and environmental data, define a chronological frame for the layers from which the artefacts were unearthed. The lower levels, including human remains, can be dated to the 350–500 kyr time span, in agreement with micromammal and stratigraphical studies.These data make Visogliano one of the oldest palaeoanthropological sites in Italy, where human remains are directly associated with protobifaces, choppers and chopping tools. In Western Europe, Visogliano is contemporaneous to the G soil of the Arago Cave, France, with which it shares several similarities in faunal assemblages and radiometric data, and which contains human remains also. These data make Visogliano as one of the oldest sites in Europe where the Acheulian culture is observed.

36. Datation par ESR de quartz fluviatiles dans le bassin de la Loire moyenne en région centre : mise en évidence de l’importance de la tectonique quaternaire et de son influence sur la géometrie des systèmes de terrasses

Abstract: Dans les vallées du bassin de la Loire moyenne, la mise en place des réseaux hydrographiques au Plio-Pléistocène et leurs variations de direction sont liées à des rejeux de failles ou à des fractures affectant le socle paléozoïque ou les séries sédimentaires mésozoïques et cénozoïques le recouvrant. Ces accidents recoupent les surfaces d’aplanissement fini-tertiaires et ont influencé la géométrie des dépôts alluviaux quaternaires.La chronologie des nappes alluviales des vallées de la Creuse, du Cher et du Loir a été récemment établie par datation ESR sur quartz fluviatile blanchi. Des anomalies dans les corrélations entre les âges obtenus pour certaines formations et leurs altitudes relatives ont été observées. Elles sont interprétées comme une preuve d’activité tectonique régionale importante ayant localement affecté les dépôts quaternaires de ces vallées. Plusieurs phases d’activité tectonique durant le Pléistocène inférieur et moyen ont ainsi été mises en évidence. Elles ont entraîné des mouvements, souvent localisés, dont l’amplitude peut parfois être largement supérieure à cinq mètres. During the Plio-Pleistocene, the developpement of the fluvial river system of the Middle Loire Basin and the changes of its directions resulted of faults or fractures reactivations which affect the basement and the Palaeozoic sedimentary cover. The Tertiary surfaces were affected by these faults which have then modified the geometry of the Quaternary alluvial deposits. The geochronology of the Creuse, Cher and Loir fluvial deposits was recently established using the ESR method applied to bleached fluvial quartz. Anomalies between the ESR ages and the relative altitudes of some formations in the different valleys have been observed, suggesting that important tectonic movements have locally affected the Quaternary deposits. Evidences of several tectonic phases during the Lower and the Middle Pleistocene are reported. They induced vertical movements of local importance, until more than 5m.

Abstract: International audience; The archaeological site of Payre (France) yielded Middle Palaeolithic layers with Neanderthal remains, which are partly bracketed by two stalagmitic flowstones. To obtain a precise chronological framework for the human occupation and the faunal remains of this site, several dating methods were used: uranium-series (U-series by alpha spectrometry and TIMS) and electron spin resonance (ESR) on stalagmitic flowstones, combined ESR/U-series on teeth and bones, and thermoluminescence (TL) on burnt flints. Most of the ages obtained for levels H to C range from 300 to 140 ka. The age-spread obtained for the anthropic (burnt flints) and faunal remains (bones and teeth) suggests that the dated levels represent several human occupation periods, near the transition from MIS8 to MIS7 (levels G–F) and from MIS6 to MIS5 (levels D–E).

Abstract: This article presents and discusses the chronological layout of the final Mousterian and Uluzzian levels of Fumane Cave in northern Italy using 14C, ESR and TL methods. Given its complex sedimentary and cultural succession, Fumane is a key site to assess the Middle-Upper Palaeolithic transition in Southern Europe and to explore Neanderthal behaviour and to compare it with the first Aurignacians. Large ranges defined by the ESR and TL dates cover the radiocarbon ages for units from A11 to A4, respectively, from 42.8 to 32.5 ka BP become progressively younger in agreement with the stratigraphy, despite high dispersions within the same unit. Our estimates using chronometric data seem to support the hypothesis that the sequence may cover almost 10,000 radiocarbon yr and that from comparison with the sedimentological and palaeoecological data, the late Middle Palaeolithic and the early Upper Palaeolithic at Fumane occur in sediments formed under moderately cool to mild climatic conditions correlated to the Hengelo-Interstadial, shifting towards cooler and drier conditions. Finally, comparisons between the Fumane data set and other sites in the North-Adriatic region are discussed. © 2008 Elsevier Ltd. All rights reserved.

Abstract: Before ESR/U-series models were applied to ungulate teeth, it is generally assumed that calculated ages are close to the “real” ages when they range between the values obtained with the EU and LU models. When the samples show signs of uranium-leaching, a realistic mathematical modelling of the age is not possible. On the other hand, some samples have undergone a very late U-uptake “affecting” directly the U-series ages and rendering the calculated ages younger. We present results obtained on two open-air sites, which show the limits of such combined models in the case of late uranium incorporation. For the Middle Pleistocene site of Isernia la Pineta (Italy), the ESR dates are expected to fall within the limits imposed by the Ar–Ar results. The other site, the Lower Palaeolithic deposits of Ambrona (Spain), yielded two sets of samples: some at the top of the sequence with uranium uptake ranging between EU and LU limits and thus giving a good idea of the “real” age of the site; others at the base displaying a very late U-uptake, which render an age determination difficult.

Abstract: International audience; The Somme Valley, Northern France, is famous for its archaeological sequence, where numerous rich Palaeolithic sites, such as Saint-Acheul, the type site of the Acheulian, have been discovered. The archaeological levels are often directly associated with fossil alluvial sediments of the River Somme or with slope deposits, including loess and palaeosols. In the middle reaches of the valley, near Amiens, the system of fossil-stepped fluvial terraces is particularly well developed and preserved, and occurs on 10 alluvial formations. These terraces, from +5 to +55 m above the present-day valley bedrock, allow the study of the environmental changes and the human settlement of this area through the Pleistocene.Since 1988, ESR dating was systematically applied on bleached quartz extracted from the fossil fluvial deposits, in order to better describe the geological evolution of the stepped system. More recently, U-series/ESR dating has also been performed on teeth collected from the different terrace deposits. Here we present a synthetic review of the main ESR results, and propose an ESR chronology for the geological evolution of the Somme fluvial system and for the Middle Pleistocene human settlement of northern France.

42. Contribution of ESR dosimetry for irradiation of geological and archaeological samples with a 60Co panoramic source

Abstract: A very precise dosimetry of a field of artificial irradiation is essential to estimate an accurate ESR Equivalent Dose (ED) in archaeology and geology. Archaeological powder samples and one sample of DL-alanine powder as control were prepared by IPH. Some alanine dosimeters of LMRI, constituted of L-alanine pellets, were joined to the IPH samples and together, irradiated in boxes using panoramic 60Co source under different experimental conditions. The LMRI had in charge the control of the process of irradiation and the measurement of each absorbed dose and dose rate delivered to the different series of boxes. This study consists in the evaluation of the distribution of dose on the samples. The ESR measurements made by the two laboratories were analysed and then compared. These experiments showed a significant gradient in the absorbed dose delivered to each LMRI dosimeter. The dispersion in each box was easily observable. However, a good agreement between the dosimeters and the alanine powder was observed in a same box.

Abstract: International audience; Hominid remains found in 1994 from the stratified Gran Dolina karst-filling at the Atapuerca site in NE Spain were dated to somewhat greater than 780 ka based on palaeomagnetic measurements, making these the oldest known hominids in Europe (sensu stricto). We report new ESR and U-series results on teeth from four levels of the Gran Dolina deposit which confirm 2 the palaeomagnetic evidence, and indicate that TD6 (from which the human remains have been recovered) dates to the end of the Early Pleistocene. The results for the other levels are consistent with estimates based mainly on microfaunal evidence, and suggest that TD8, TD10 and TD11 date to the Middle Pleistocene.
