• Resumen

  • In this paper the mineralgy of four sequences of the Arcillas de Jimena Formation. The mineralogical composition of the fine fraction is characterized by the association: Kaolinite-illite- smectite-palygorskite-chlorite. The smectites predominate in this formation and in the richest levels there is a growth of authigenic Mg-smectite and fibrous palygorskite, while the detritic minerals (kaolinite, illite) decrease or disappear. The chlorite is concentrated in the carbonate levels and it is a authigenic mineral.
