Abstract

Morphological, petrological and geochemical features of the felsic domes in Tenerife are treated. Two main groups have been established: Old Edifices Domes and Recent Series Domes, subdivided in minor groups according to their volcano-stratigraphic position. There are many morphological types, each group showing different typical characters. Haüyne phonolites are the most common rocks, although nepheline phonolites and trachytes are also present. Chemical analysis indicate major abundance of undersaturated terms and higher differentiation in the Recent Series Domes than in the üld Edifices Domes. Both groups are clearly separated in usual diagrams and specially show different trends in Al, Fe, K, Ti, Nb, Y and Ce elements
