enstatiit
Enstatite is a common pyroxene mineral with the chemical formula MgSiO3. It is typically found in igneous and metamorphic rocks, as well as in stony meteorites. Enstatite is characterized by its green to brown color and its prismatic crystal structure. It is named after the German mineralogist Gustav Rose, who first described the mineral in 1808.
Enstatite is a member of the pyroxene group, which includes other minerals such as diopside and augite.
Enstatite is often found in association with other minerals such as olivine, plagioclase, and magnetite. It
Enstatite is a relatively common mineral, but it is not typically sought after for its aesthetic value.
