%X Clay minerals from the volcaniclastic deposits of the three different sedimentary settings (paleosolscontinental lacustrine and transitional fan delta) have been studied by X-ray, MEB y TEM. The clay fractionof Ihis sediments consist largely of smectite (saponite) with minor irregular chlorile-smectite mixed layersand illite: they occur as replacement of ferromagnesian minerals, plagioclase microlites and glass matrix ofthe volcarenite and they are inferred to be direct diagenetic alteratíon products of volcanic components.
