Large-scale rescue excavations prior to the construction of the TGV (Train à Grande Vitesse) Mediterranean railway have considerably increased the corpus of palaeoenvironmental data concerning the middle Rhone valley (latitude 44/45° degrees North). The establishment of a regional chrono-stratigraphical framework, based on more than 200 14C...

Geoarchaeological, palaeoecological, cultural and spatial archaeological research carried out in the Middle Rhone Valley, between Valence and Orange, in the context of rescue archaeology, provides new results on the factors explaining the proto-historical landscape evolution of the North-West Mediterranean Basin. The study of a major...

The rescue excavation of the site of Fortuneau, though still in progress, has provided an opportunity to apply precise excavation and sedimentary analysis methods to large surfaces of a habitat occupied two times during the Final Bronze Age. This double methodology compensates for the limits imposed by the instability of anthropogenic...

The reliability of phytolith assemblage analysis for characterizing Mediterranean vegetation is investigated in this study. Phytolith assemblages are extracted from modern and buried Holocene soils from the middle Rhône valley (France). The relation between modern phytolith assemblages and the surrounding vegetation, as well as between fossil...

The neolithic levels of the rock-shelter "La Grande Rivoire" are composed of a multitude of sedimentary layers of very contrasting colour. Sedimentological analyses show that the fine fractions, mainly silty and rather strongly carbonated, have principally two origins : on the one hand an important accumulation of herbivores faeces due to the...

Elle entraîne l'apparition de nouveaux risques et de nouvelles vulnérabilités, souvent peu anticipés par les acteurs néolithiques, porteurs d'une nouvelle économie...
