On thebasis of chemical and mineralogical compositional features two groups could be considered. 80th groupsare alkaline, the first normal alkaline (in the Cofete Area) and the second one more alkaline (in theMungía Area). When the proportions of crystallizing phases are estimated, these two groups show differentbehaviour. The first group is controlled by olivine and c1ynopiroxene and the second one by these twophases plus plagioclase and magnetite. These two different evolution paths culminate with also twodifferent more differentiated members. The basic rocks in the Cofete Area are related to the trachytes ofMontaña Azufrá whilst these in the Mungía Area are connected to the felsic rocks of Cofete Islet. %~
