Edades 40Ar-39Ar del Complejo Basal de la isla de La Gomera

This essay shows some new dating of the Basal Complex of La Gomera Island and among them, the first ones obtained using the 40Ar-39Ar methodology. Two of them are rocks of the Submarine Edifice. In the first one we obtain an age of 11,49 ± 0,66 Ma by the 40Ar-39Ar method, and in the second one 11,4...
