Abstract

Three regional tectonic phases can be distinguished during the past million years: 1. formation of a large graben, 2. sinking of segments of the volcano complex, 3. faulting, accompanied by phreatomagmatic volcanism. Each event was followed by small volume eruptions of basic, unevolved potassic magma. Subsequent eruptions produced more differentiated rocks. The tectonic activity created room for magma at shallow level, where crystallization and minor magma mixing took place.
