Abstract

The Conques cave near Vingrau is the only Magdalenian site in the Department of the Eastern Pyrenees to have been the subject of a scientific excavation. It was discovered in 1971 during a prospection campaign by P. Campmajo and H. Baills. In general the size, form, and nature, of the magnetic grains in a sediment are the result of many physico-chemical or mechanical processes taking place from the transport of the sediment to its deposition (consolidation?). The study of the susceptibility and other magnetic parameters allows a better understanding of the history and the naure of these grains, to clarify the stratigraphy of the sedimentary deposit and even to infer the climatic variations by comparison with the results from other techniques. The results obtained in the present study show a good correlation with the sedimentological study and indicate the presence of three layers, which are magnetically different.
