RM2719   Humite with sodalite and phlogopite

Monte Somma, Complesso del Somma-Vesuvio, Napoli, Campania, Italy

Exceptional very good sized specimen of humite, a rare magnesium fluorosilicate, from the type locality for the species: Monte Somma. In the piece we can see numerous crystals of an orange tone, defined and some with rounded shapes, brilliant and with transparence. They are accompanied by micaceous phlogopite crystals and white aggregates of sodalite.
Humite is a species closely related to norbergite, chondrodite and clinohumite. These minerals are very difficult to distinguish. Humite appears to have a smaller field of stability than clinohumite, chondrodite and norbergite. Humite is often associated with one or more of the other species of the humite group, as intergrowths.
