Abstract

International audience; Dendro-archaeological contribution to the history of forest exploitation. The case of the Gallo-Roman settlement of Oedenburg (Alsace, France) between 10 and 180 AD summary Dendrochronology has never been considered as simply a dating tool. In addition to the dates, which are always based on a regional scale signal, tree-ring series can provide information about forest structure and woodland development. Our study of the settlement of Oedenburg, established in the Rhine Limes of the Roman Empire, was conducted within this framework. The dated series provide a description of some structural aspects of oak-stands that were exploited for construction. In this aim, the analytic tools employed are "age trend patterns" and series classification or dendro-typology. The archaeological series were also compared to modern forest characteristics. Throughout the chronology, woodland development appears dominated by two stages. The first is oak tree harvest. We observe that (1) series patterns from a single archaeological structure are more similar than between structures, and (2) wide tree rings are present during the juvenile phase. These rings are wider than those observed consecutively in modern logging. The effect of oak tree harvesting is local high-forest clearing. During the second stage, the high forest is in the process of recovery. After a few years of aging, Gallo-Roman oak ring width becomes sharply inferior to that observed in the actual forest. This can be explained by the high degree of competition between trees due to a poor thinning grade during recovery. Within the chronology, stands were first exploited using a harvest and recovery system; second, supply may have focused Key words forest structure / Gallo-Roman logging / dendro-typology / age growth trend / Quercus sp. on preserved trees; and third, the regeneration rate was respected , but harvest age was lowered, resulting in stronger thinning of a stand, although they appear denser than present day managed high forests.

Abstract

International audience; Magnetic susceptibility, surface rock soiling, elemental composition and lead isotope ratios were measured in surface stone samples collected at different heights of a late 19th century building in Dijon, France. We targeted four limestone facades that differ in orientation and proximity to car traffic. It seems that zinc, copper, sulphur and cadmium are present as diffuse pollutants in urban atmosphere, at least at the scale of the building studied. In contrast, lead and arsenic exhibit point sources: automotive traffic and past coal-burning fly-ash emissions; both coherent with lead isotopic composition measurements. Parameter variations primarily result from exposition to rain washing or micro-scale runoff, and from the closeness, magnitude and origin of anthropogenic sources. Both anthropogenic particles and natural dust tend to be similarly affected by deposition/soiling and rain washing, which act dynamically as competitive processes. Examination of archival photographs suggests that soiling predominated in the past, when the air was rich in black dust, whereas equilibrium or even weathering may occur nowadays due to recent improvements or at least changes in air quality. Using the chemical composition of building facades to provide insights into the magnitude and dispersion of urban atmospheric pollutants may not always be straightforward because of uncertainties related to the period of accumulation.

Abstract

International audience; Combining fieldwork and surface data, we have reconstructed the Cenozoic structural and tectonic evolution of the Northern Bresse. Analysis of drainage network geometry allowed to detect three major fault zones trending NE-SW, E-W and NW-SE, and smooth folds with NNE trending axes, all corroborated with shallow well data in the graben and fieldwork on edges. Cenozoic paleostress succession was determined through fault slip and calcite twin inversions, taking into account data of relative chronology. A N-S major compression, attributed to the Pyrenean orogenesis, has activated strike-slip faults trending NNE along the western edge and NE-SW in the graben. After a transitional minor E-W trending extension, the Oligocene WNW extension has structured the graben by a collapse along NNE to NE-SW normal faults. A local NNW extension closes this phase. The Alpine collision has led to an ENE compression at Early Miocene. The following WNW trending major compression has generated shallow deformation in Bresse, but no deformation along the western edge. The calculation of potential reactivation of pre-existing faults enables to propose a structural sketch map for this event, with a NE-SW trending transfer fault zone, inactivity of the NNE edge faults, and possibly large wavelength folding, which could explain the deposit agency and repartition of Miocene to Quaternary deformation.

Abstract

International audience; The site of the sanctuary of Ribemont-sur-Ancre (Somme, France) is of major scientific interest for the knowledge of the Celtic civilization in Europe. It also presents other peculiarities: two clearly identifiable periods of occupation-the first one as early as third century BC-to the second century AD and the second one from 1914-1918. In the area disrupted through military operations, the remains of several epochs are intermingled. In order to obtain a precise knowledge of the space time organisation of each occupation, a magnetic survey was carried out. The comparison of geophysical results with the aerial photographs shot during the war allows an exact determination of the origin of the anomalies. It becomes possible to separate the magnetic anomalies which are contemporary, anterior or probably posterior to the conflict of 1914-1918. The range of magnitude and the sign of polarity of anomalies appear as a means to facilitate the identification of the features of each period. Among the anomalies detected, some of them, such an the elliptic enclosure, have been identified by the excavations as unknown archaeological remains. Generally speaking, the ability of the magnetic method for surveying any structure in such a disrupted environment suggests a more frequent use in prospecting of the sites which were battlefields in Historic periods.

Abstract

International audience; We present results to show that the Beaune P & C borehole, cored in the Bresse Basin (France), records late Pliocene climatic variations. Pollen analysis allows precise correlations with northern and southern European stratigraphies. Using Kukla et al.'s (1981) climate index, we show that cold climate phases occur during the Brunssumian, at around 3.2, 3.6 and 5.2 Myr B.P., respectively, in agreement with Atlantic core results. The onset of a general cooling trend is felt early in the Reuverian, at about 3 Myr B.P. which corresponds to the end of a warm event characterized by high percentages of oak. This is followed by minor climatic pulses of increasing magnitude since about 2.7 Myr B.P., that are also recorded in marine sediments. Finally a major cooling occurs at about 2.4 Myr B.P., corresponding to the beginning of the Praetiglian.
