The clay fraction of this sediments consist largely of smectite (saponite) with minor irregular chlorite-smectite mixed layers and illite; they occur as replacement of ferromagnesian minerals, plagioclase microlites and glass matrix of the volcarenite and they are inferred to be direct diagenetic alteration products of volcanic components}, publisher = {Sociedad Geológica de España}, title = {Procesos de transformación y neoformación de esmectitas en los materiales volcanoclásticos de la isla de La Palma (Canarias)}, title = {Processes of transformation and heoformation of smectites in the volcaniclastic deposits from the La Palma (Canary Islands)}, author = {Vegas Salamanca, J. and García Romero, E. and Marfil Pérez, Rafaela}, }
