Resumen

The Submarine Edifice rocks are the oldest rocks in La Gomera. This edifice is made up of submarine lava
and breccias, with marine sediments associated, all of which is transverse by a very dense network of
diques. This essay shows the first geochemical and mineralogical submarine volcanic rocks data. These
rocks are intensely altered and have an alkaline chemical affinity. Compositions vary between alkaline
basalts and trachyandesites, and all of them show typical Within Plate and Ocean Island basalts immobile
elements contents. The latter Subaerial Edifice volcanic rocks are similar in composition, although they are
slightly less alkaline and they have less evolved types.
