摘要:Among the paintings and engravings found in the Chauvet-Pont d'Arc cave (Ardèche, France), several peculiar spray-shape signs have been previously described in the Megaloceros Gallery. Here we document the occurrence of strombolian volcanic activity located 35 km northwest o...

摘要:Abstract(#br)The Sidi Messaoud site provides a 40 m thick sedimentary infilling of great importance for the study of environmental changes and landscape evolution during the Upper Pleistocene in the Western Sahara. In this study, chronological results obtained by the 14 C, U...

摘要:Abstract(#br)In this article, we present a first synthesis of the chronology of Cussac Cave (Dordogne, SW France). This deep cavern (1.6 km), discovered in 2000, is very well preserved ( e . g . intact floors) and thus favorable to research, especially given its rare associa...

摘要:Abstract(#br)Sauvet et al. (in press) present a partial description of the Uranium-series or 230 Th/ 234 U dating method, which leads them to criticize this dating tool and claim that this method provides “ an extremely wide range of uncertainty providing a weak base upon wh...

摘要:Abstract(#br)While reviews of comparisons between multi-grain OSL ages and independent chronological information are available in the literature, there is hardly any such performance test for single-grain OSL ages. And yet, this is all the more needed as the interpretation o...

摘要:Abstract(#br)The radiation dose delivered by the 90 Sr beta source of a TL-OSL reader and the one delivered by a 137 Cs gamma source were compared using OSL dating techniques and tools. Three sets of quartz of different origins (rock, sediment and loess) were studied and measured...

摘要:Abstract(#br)The transition from the Lower to the Middle Paleolithic in the Levant is a crucial event in human evolution, since it may involve the arrival of a new human population. In the current study, we present thermoluminescence (TL) dates obtained from 32 burnt flints ...

摘要:Abstract(#br)Because only a few radiometric data are actually available, the chronology of the Amudian – a blade-dominated industry of the Acheulo-Yabrudian Cultural Complex (AYCC) of the late Lower Paleolithic in the Levant – is still not well constrained. Qesem Cave offers...
