Pyroxene Group

This page is currently not sponsored. Click here to sponsor this page.

Name:Named in 1796 by Rene Just Haüy from the Greek words for fire (πυρ) and stranger (ξένος). Pyroxene was named because of its presence in a glassy or vitreous lava. Pyroxene was believed to be an impurity in the glass, and therefore a "stranger to fire" and not formed by the action of heat. Pyroxene was originally what might now be called "augite", but the name has been raised as a group name of structurally and chemically similar minerals.

A large group of inosilicate (chain silicate) minerals with the general formula ABSi2O6.
It is divided into the Clinopyroxene Subgroup (monoclinic) and the Orthopyroxene Subgroup (orthorhombic).

The most recent nomenclature is given by Morimoto (1988, 1989).
