The same minerals were found in the forteen analyzed layers : illite, montmorillonite, chlorite, kaolinite, quartz, calcite, dolomite, but their relative proportion is not identical in all the layers and lateral variations are even noticed in the same level. Nevertheless in all layers, the clay fraction is essentially composed of illite and montmorillonite, while chlorite and kaolinite are weakly occuring.Dans les 14 couches analysées on trouve les mêmes minéraux : illite, montmorillonite, chlorite, kaolinite, quartz, calcite, dolomite, mais leur proportion relative n'est pas identique dans toutes les couches, et l'on constate même, dans un niveau donné des variations latérales. Néanmoins, dans toutes les couches, la fraction argileuse se...
