The «areniscas del Aljibe» are bimodal materials formed by eolic quartz with either clay or ferrous coatings and quartz sintaxial cemento The total mineralogical composition of the rocks and the fine fraction is very homogeneous in the sequences studied. The clay fraction is formed by kaolinite, illite and interstratified illite-5mectite. These minerals have variable origins, Thus, detritaI kaolinite pM and autbigenic kaolinite with high crystalinity are common, together with detrital illite and fibrous neoformed illite. Tbe smectite content of the mixed-layerd mineraIs suggests a different degree of diagenesis and a diverse paleogeographic situation for these sequences.
