Hypersten
Sign in to saveHypersthene is a common rock-forming inosilicate mineral belonging to the group of orthorhombic pyroxenes. Its chemical formula is . It is found in igneous and some metamorphic rocks as well as in stony and iron meteorites. Many references have formally abandoned this term, preferring to categorise this mineral as enstatite or ferrosilite. It forms a solid solution series with the minerals enstatite and ferrosilite, being a mid-way member between the two. Pure enstatite contains no iron, while pure ferrosilite contains no magnesium; hypersthene is the name given to the mineral when a significa

Hypersten är ett rombiskt kristalliserande pyroxenmineral innehållande järn och magnesium. Sedan 1988 är det ett diskrediterat mineralnamn. Sammansättningen ligger mellan ändleden enstatit Mg2[Si2O6] och Fe2[Si2O6]. Mineralet har svart till svartbrun färg, glasglans och tydliga genomgångar. Hypersten förekommer i basiska eruptiva bergarter, såsom hyperstengabbro, norit och hyperit.
