CAVANSITE SPECIMENS

Cavansite, whose name is derived from its chemical composition, calcium vanadium silicate, is a deep blue phyllosilicate mineral. It occurs in basaltic and andesitic rocks and is typically associated with zeolites. Cavansite tends to form deep blue crystal aggregates, generally in the form of balls up to a couple centimeters in size. The vast majority of cavansite comes from the Deccan Traps, a large igneous formation in the Pune Province of India and one of the largest volcanic features on Earth.
