Resumen

This work studies the modifications undergone by the Creen Clays Saponite in the Tagus Basin subjected to
activation treatments, and stresses the influence of the development of the electronic microscopy technique for
studying these materials. Acid treatment with HU and pillaring treatment with Al13 were performed.
Characterization of the samples was carried out by DRX, chemical analysis of majar elements and Transmission
Electronic Microscopy. Acid treament causes the delaminarion and fragmentation of the particles, partially
dissolving the octahedral layer and generating amorphous silica, coming from the tetrahedral layer. Pillaring
treatment gives rise to a stable salid with interlayer spadng at 18A. The high number of crystalline defects
present in the saponite conditions the formation of a low number of pillars per cell.
