| Resumen: |
The 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. 80th groups are alkaline, the first normal alkaline (in the Cofete Area) and the second one more alkaline (in the Mungía Area). When the proportions of crystallizing phases are estimated, these two groups show different behaviour. The first group is controlled by olivine and c1ynopiroxene 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 Montaña Azufrá whilst these in the Mungía Area are connected to the felsic rocks of Cofete Islet. |
