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 componentsspaAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/SmectiteSaponiteVolcaniclastic depositsDiagenetic alterationCaldera de TaburienteLa PalmaCanary Islandsjournal articleopen access
