About Pyroxene GroupHide

Formula:

ADSi₂O₆

Name:

Named in 1796 by René 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 ADSi₂O₆.
It is divided into the Clinopyroxene Subgroup (monoclinic) and the Orthopyroxene Subgroup (orthorhombic).

The most recent nomenclature is given by Morimoto et al. (1988).

Varieties of Pyroxene GroupHide

Al-pyroxene	Variety of Pyroxene with 25% of tetrahedrally coordinated sites occupied by Al. Originally described from Oka complex, Oka, Deux-Montagnes Co., Québec, Canada.
Augite-Bronzite	Supposedly a variety of the pyroxene group between Augite and the Enstatite group. Possibly either pigeonite or a mixture with augite and enstatite as there is very little solid solution between these three minerals.
Fe-rich pyroxene	A petrological description for iron-rich pyroxene. Usually, but not always, this indicates hedenbergite.

Click on any node to view relationships. Formula-derived relationship network for the group members above. Use Find related species to add formula-neighbour species outside the current group view. Solid links show inferred chemical differences; dashed violet links show same-formula crystallographic differences. Hydration states are not treated as relationship changes. These relationships do not imply any real-world substitution reactions between these species.
