Abstract

The chemical analysis of quaternary deposits allows us to bring extra information and to make more exhaustive the various and usual sediment ologic analyses. The techniques which are used in order to extract the chemical elements are simple and easily earned out. The study of the variation of the amount of iron, manganese, aluminium, silicon, calcium, magnesium, sodium and potassium of the different levels of a prehistoric site may provide many information as regards the conditions under which a level has been formed (paleoclimatology). This method, when applied to two different materialized examples, proved to be of a great use and allowed us to suggest a paleoclimatic interpretation of the Würm III in the area of Gavaudun (Lot-et-Garonne).
