Article
Full-text available
Natural metal background levels in sediments are critical to assess spatial and temporal trends of contamination in hy- drosystems and to manage polluted sediments. This is even more sensitive that multi-factors such as geogenic basement, depositional context, and past or long-term pollution can af- fect the level of metals in sediments. This artic...

The NeoArabia project tries to understand how environmental, social, economic and technological factors work in concert to influence settlement and abandonment along a latitudinal transect of 1200 km from UAE to southern Oman. This region was affected by wide north–south variations in the Indo‐Arabian monsoon, marine upwelling activity and eustatic...
Article
One of the main drivers of overbank fine deposition and floodplain formation is the hydrological connectivity between the channel and the floodplain. Channel correction (i.e., groyne field construction within the main flow channel and secondary channel disconnections) and flow regulation can typically lead to a disconnection of riverine floodplains...

A multi-proxy study (litho-stratigraphical survey, magnetic susceptibility, organic matter content, palaeoecology) has been conducted on organic and detrital deposits from the Gage Valley (Upper Loire Basin). This research aims at accurately describe the evolution of this little floodplain over the last 1,500 years, in a medium mountain range conte...

Adaptation of local populations to climate change over time is one of the main concerns of the PALEOMEX-MISTRALS program (INEE-INSU funding). This research project promotes new geoarchaeological and palaeoenvironmental studies on the Middle Atlas Mountains (Morocco - fig. 1). This area presents a high archaeological potential and numerous lacustrin...

Cette étude offre une description très précise de l'aspect d'une petite plaine alluviale en moyenne montagne au Moyen Age.
Article
Full-text available
Une recherche paléoenvironnementale et géoarchéologique pluridisciplinaire a été conduite dans le bassin supérieur du fleuve Loire en vue d’apprécier, à partir d’une chronostratigraphie multi-proxy, la variabilité des flux hydro-sédimentaires dans les têtes de bassin du réseau hydrographique à l’échelle de l’Holocène. Sur la base de 107 datations p...
Article
A paleoenvironnemental and geoarchelogical pluridisciplinary and multi-proxy research was carried out on the upstream Loire basin to study the hydro-sedimentary flows wich have affected headwaters of the hydrosystem during the Holocene. A set of 107 radicarbon dates support the results. A statistical analysis (Cumulative Probability Density Functio...
Article
Full-text available
This paper focuses on early Holocene rapid climate change (RCC) records in the Mediterranean zone, which are under-represented in continental archives (9.2 to 8.2 ka events) and on their impact on prehistoric societies. This lack of data handicaps the general interpretation of climate impacts on human societies, which flourished in recent years. Ke...
Conference Paper
The Linear Band Ceramic (LBK) culture represents a major event in the spread of agriculture in Europe. Occupation particularly occurred in river valleys, with largest densities found along the rivers Danube, Elbe and Rhine. The interaction between the emergence of this culture and the dominant climatic and hydrological conditions is not yet fully e...
