PYROXENE The pyroxenes are a group of common and important Ca-, Mg-, and Fe-bearing silicate minerals There are dozens of specific minerals in the pyroxene group These include augite, diopside, hedenbergite, pigeonite, enstatite, bronzite, hypersthene, ferrohypersthene, eulite, and ferrosilite
Pyroxenes | Earth Sciences Museum | University of Waterloo Pyroxenes are the most significant and abundant group of rock-forming ferromagnesium silicates They are found in almost every variety of igneous rock They also form under conditions of regional and contact metamorphism Their conditions of formation are almost exclusively restricted to environments of high temperature, high pressure, or both
