Abstract
Several trachytic and phanalitic, radial and canical dyke-swarms crap out an the La Gomera narthern regian. The first age data abtained situate the intrusian episades coinciding in time with the extrusian af the Old Basalts. The earlier dykes shaw a radial pattern, centred in Tamargada. They have been dated in 8.0 Ma and 7.9 Ma. The canical swarm centred farther west, in Vallehermasa, has a slightly more recent age, between 7.5 Ma and 6.4 Ma. A third dyke-swarm is spatially assaciated with the canical structure and has likely a similar age.
