dc.description.abstractThe Southern Volcanic Complex I consists mainly of basalts with scarce felsic members. On the basis of chemical and mineralogical compositional features two groups could be considered. Both groups are alkaline, the first normal alkaline (in the Cofete Area) and the second one more alkaline (in the Mungia Area). When the proportions of crystallizing phases are estimated, these two groups show different behaviour. The first group is controlled by olivine and clynopiroxene and the second one by these two phases plus plagioclase and magnetite. These two different evolution paths culminate with also two different more differentiated members. The basic rocks in the Cofete Area are related to the trachytes of Montana Azufra whilst these in the Mungia Area are connected to the felsic rocks of Cofete Isleten_US
