Resumen

A volcanic submarine formation cropS out in the north coast of Tenerife, east of San Juan de la Rambla. This unit is formed by massive and pillowed lavas, pillow-breccias, hyaloclastites and palagonitic tuffs and is interpreted as consisting of subaerial lavas that flowed into shallow marine waters. The lavas are amphibolic trachybasa/ts. An una/tered sample coming from the most massive zone has yielded a whole rock 2.60±0.17 Ma 1<-Ar age. These submarine lavas are underlying the oldest formations of the Las Cañadas Series dated at 1.24 Ma in that same area. The submarine lavas correspond to a time period for which very scarce information was yet available in Tenerife
