“…Other sections of slope deposits located in Charente on Jurassic limestone show palaeosols that were mentioned by Dewolf and Guillien (1962), Guillien (1965), Ducloux et al (1970), Ducloux (1972), Ozouf (1983) and Ozouf et al (1995) and were attributed to interglacial or interstadial periods. However, the palaeosols have not been precisely described and analysed, except by Ducloux (1972) and Ducloux et al (1970).…”

“…It would have formed in a well-drained temperate or cold context. At Echoisy, Guillien (1965) reported a red palaeosol attributed to the Eemian interglacial with burrows of marmots or ground squirrels. It is associated with an abundant molluscan fauna composed solely of individuals of the species Cepaea hortensis (J.J. Puisségur, in Guillien, 1965).…”

The 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 the identification 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 solifluction lobes, developed mainly after ca. 40 ka, i.e. during late MIS 3 and MIS 2. MIS 3 is recorded as a palaeosol complex including two humic A horizons overlying a chromic cambisol associated with burrows of ground squirrels, while MIS 5 corresponds to a reworked rubified chromic cambisol. Overall, this sequence shows similarities with the clastic deposits found in regional cave porches and rock shelters, strongly suggesting that anthropogenic activities did not significantly modify the climate‐driven sedimentary and soil‐forming processes at the Palaeolithic sites.
