This unit is formed by massive and pil/owed lavas, pillow-breccias, hyaloc/astites and palagonitictuffs and is interpreted as consisUng of subaerial lavas that flowed into shal/ow marinewaters. The lavas are amphibolic trachybasalts. An unaltered sample coming fram the most massivezone has yielded a whole rack 2.60±0.17 Ma K-Ar age. These submarine lavas are underlyingthe oldest formations of the Las Cañadas Series dated at 1.24 Ma in that same area. The submarinelavas correspond to a time period for which very scarce information was yet available in Tenerife. %~
