dc.description.abstractEnThe 12 m thick sequence of calcareous slope deposits and palaeosols exposed in a quarry at Verteuil(southwest France) has been studied and dated by optically stimulated luminescence. Emphasis was given to theidentification and characterisation of palaeosols through geochemistry and micromorphology. The main clastic units,separated by major unconformities, were dated to MIS 6, MIS 5–4 and MIS 3–2. Stratified deposits (‘grèzes litées’),consisting of alternating diamictic and matrix‐free clastic beds and attributed to stacked stone‐banked solifluctionlobes, developed mainly afterca. 40 ka, i.e. during late MIS 3 and MIS 2. MIS 3 is recorded as a palaeosol complexincluding two humic A horizons overlying a chromic cambisol associated with burrows of ground squirrels, whileMIS 5 corresponds to a reworked rubified chromic cambisol. Overall, this sequence shows similarities with the clasticdeposits found in regional cave porches and rock shelters, strongly suggesting that anthropogenic activities did notsignificantly modify the climate‐driven sedimentary and soil‐forming processes at the Palaeolithic sites.
