We can deduce from the spatial distribution of the global mineralogy and the clay mineralogy, that the basin seems to be an homogeneous and uniform one; with a general predominance of quartz feldspars and clays, and a high quantity of carbonate in the southward areas of the basin. The clay fraction is represented by caolinite, illite and smectite. This mineralogical association corresponds with the proximal facies of continental basin.
