Quick Summary

Clinoenstatite is a mineral belonging to the pyroxene family, specifically a monoclinic magnesium-iron silicate with a greater proportion of magnesium than iron. It is the magnesium silicate MgSiO₃. While enstatite is the stable form of magnesium silicate at low temperatures, clinoenstatite is an unstable form that also occurs at low temperatures. Enstatite and protoenstatite crystallize in the orthorhombic system, whereas clinoenstatite crystallizes in the monoclinic system. Clinoenstatite forms a series with clinoferrosilite, similar to the enstatite-ferrosilite series.12
