Nuevas edades K-Ar de las rocas volcánicas de la isla de Tenerife

Six new isotopic age determinations were established in volcanic rocks of Tenerife. These data belong to different units of the main volcanic edifices and the results allow us to get a more accurate knowledge of the eruptive history of the island. One of these ages corresponds to a trachyandesitic f...
