Uralite and Uralitization

Uralitization: deuteric alteration, Textural and mineralogical changes occuring within an igneous rock during the final crystallization stages, Uralute is a common product of deuteric alteration on Pyroxene.

Uralite is a pseudomorphs of hornblende group minerals, mainly actinolite, after a pyroxene group mineral, mainly augite. Originally described from the Urals Region, Russia.
