Abstract

A 1:28,000-scale geoarchaeological map has been prepared for a large sector of the Ionian coastal belt of the Basilicata region, southern Italy, in order to investigate the relationships between the spatial distribution of archaeological sites of Greek settlement of Metapontum and the main landforms of this sector of the Bradano Foredeep. Archaeological investigation consists of an examination and a re-organisation of published data and new field surveys, which has allowed us to infer the relationships between landform elements and spatial distribution of about 1400 archaeological remnants of the Greek colony of Metapontum. Our results highlight a non-random distribution of the archaeological evidence and the strong influence of geomorphological features and processes on the settlement pattern. [ABSTRACT FROM AUTHOR]

Abstract

In this work a detailed geomorphological study aimed to reconstruct the Holocene evolution of a slope largely affected by landsliding is presented. The study area is located in the lower valley of the Tanagro River, flowing in the Auletta basin, a Pliocene to Quaternary tectonic depression located along the elongation axis of southern Apennines. In order to investigate the relationships between landscape evolution and triggering factors, and to better constrain the Holocene palaeoclimate scenario in which the mass movements occurred, geomorphological data have been integrated with those deriving by the stratigraphic, chronological, and minero-geochemical analyses of the deposits genetically related to the landslide events. The investigated landslide shows a complex style of activity, with compound rotational and translational slide in the upper part of the slope evolving into flow in the lower part. The chronological evolution of the landslide activity has been constrained through radiocarbon dating of palustrine deposits, genetically related to the landslide, and of interbedded paleosols. On the basis of the presented data, the main landslide event can be placed at the beginning of the Holocene and it is followed by a period of scarse landslide activity, as demonstrated by the sedimentation of palustrine deposits within an endorheic pond. As the small basin was created by a counterslope rotation related to the main landslide phenomenon, its deposits post-date the age of the landslide. The geomorphological features related to the main gravitative event are strongly modified by reactivations occurred at the beginnings of Sub-Boreal period, which represent, in southern Europe, the warmest and wettest stage of the Holocene. As confirmed by mineralogical and geochemical data, intense and/or prolonged precipitation might have played a major role as triggering factor in reactivating the slope movement.

32. 113Cd, 1H MAS NMR and FTIR Analysis of Cd2+Adsorption on Dioctahedral and Trioctahedral Smectite

Author

Di Leo, Paola and Cuadros, Javier

Abstract

Dioctahedral and trioctahedral smectites of very low Fe contents were exchanged with Ca (0.8 N CaCl2) and then with Cd (0.004–0.2 N CdCl2), resulting in the approximate Ca/Cd interlayer compositions 100/0, 75/25, 50/50 and 0/100. The samples were analyzed using 113Cd and 1H MAS NMR spectroscopy, at different hydration states, and by FTIR using films oriented at 90 and 45° to the infrared beam. When adsorbed from low-concentration CdCl2solutions, as in this study, Cd is in the smectite interlayer as Cd2+, surrounded by water molecules. In smectite specimens with no tetrahedral charge, Cd occupies one single site in the center of the interlayer along the caxis but in smectite with tetrahedral charge, the basal oxygen atoms with excess negative charge interact with some of the Cd atoms more strongly, generating a second site in which Cd is displaced from the center of the interlayer and closer to those oxygen atoms. The 1H NMR study showed protons from hydration water and smectite hydroxyls and showed that both have more than one component. The FTIR and 1H NMR experiments indicate that Cd interacts with hydroxyl groups through one of the solvating water molecules in the first coordination sphere. Cadmium retains water molecules bridging Cd and OH groups even at low hydration states. Comparison with previous studies shows that, when adsorbed from high-concentration CdCl2solutions, Cd species other than Cd2+are present in sufficient quantities to enter the interlayer and create a different Cd-water complex, seemingly displacing Cd2+from the center of the interlayer.
