According to lithological composition three units were stablished in the area studied: a) Clayey unit. Green and pinkish clays with sandy beds and early formation of calcretes. Clay minerals association: smectite-mixed-layers (kerolite-stevensite) sepiolite-illite-kaolinite. b) Clayey calcareous unit Green clays with calcretes and a sandy level at bottom of the unit. Clay minerals association: smectite-illite-palygorskite-sepiolite-kaolinite. c) Clayey-dolomitic unit. Green clays with dolomicrites. Clay minerals association: smectiteillite-palygorskite-sepiolite. Results let us to stablish a sepiolite and palygorskite genesis related to lacustrine paludine environments where pedodiagenetic processes (v.s. carbonation, dolomitization, silici...
