This paper shows the results of the clay fraction mineralogical study of four soils profiles (Aridic Haploxeroll, Lithic Haploxeroll, Lithic Calcixeroll and Lithic Torriorthent) developed on the tholeitic basalts (jumillite) from Sierra de las Cabras (Albacete). The clay fraction is made up by a mixture of illite, vermiculite, vermiculite-smectite, kaolinite, and a very little amount of chlorite. Soil chlorite and illite mainly come from chlorite and micas of rock, while vermiculite represents a more advanced step of the mica degradation, and kaolinite (surface horizons) and the vermiculite-smectite interstratified minerals (deep horizons) are the result of neoformation
