AUGITE – (Ca,Na)(Mg,Fe,Al,Ti)Si2O6 - UFRGS
Augite is an inosilicate of the Pyroxene Supergroup . It is a very common clinopyroxene (monoclinic pyroxene), an important rock forming mineral of basic igneous rocks (basalts, etc.), but it has no economic importance. It is part of a solid solution formed by diopside (CaMgSi2O6), augite and hedenbergite (CaFe2+Si2O6).

Shonkinite
It is unique in having low silica, feldspathoid minerals, and large blocky crystals of black augite. The close view of the rocks in the Adel mountains show large glossy crystals of augite in a dark grey matrix made up of small crystals of augite and feldspar

Basanite
Clinopyroxene (augite) and olivine are common as phenocrysts and in the matrix. The augite contains significantly greater titanium, aluminium and sodium than that in typical tholeiitic basalt.

Pigeonite
Pigeonite crystallizes in the monoclinic system, as does augite, and a miscibility gap exists between the two minerals. At lower temperatures, pigeonite is unstable relative to augite plus orthopyroxene.
