Augite is isomorphous with the minerals Diopside and Hedenbergite.It is an intermediary member between these minerals, forming a series, but contains additional sodium and aluminum within its chemical structure. Strictly speaking, because of the variables in its chemical structure, Augite is really more of a group then a single mineral, but it is still …

Augite is a basic silicate mineral with high content of iron and magnesium, a so-called "ferromagnesian" mineral of the pyroxene grouping. This identifies it as a high-crystallization-temperature dark silicate, formed at early stages of the Bowen reaction series. Augite is often found as crystals in basalt.

Orthopyroxenite cumulates throughout the Critical Zone of the Bushveld Complex commonly contain prominent euhedral crystals of bottle-green augite, typically around 1 cm in size and surrounded by "haloes" of nearly pure plagioclase. On close examination, the augite grains can be seen to be oikocrysts, containing extensively …

A glass with higher iron concentration and a lower Fe 3+ /Fe tot ratio crystallizes faster and more intensely than that with low iron concentration and a high Fe 3+ /Fe tot ratio. The main crystal phases in the heat-treated glasses are, in most cases, augite and diopside but the morphology differs considerably.
