Abstract: | Several trends of differentiation have been observed in the Etna lavas. Such trends, starting from an olivine basaltic magma, lead to the formation of hawaiites and mugearites, tephrites or latite-andesites. These lavas alternate in time and space, according to variations of the local tectonic conditions connected with the subsidence of the Ionian Sea and the uplift of northeastern Sicily. |
