Brachina meteorite

The Brachina meteorite is the type specimen of the brachinites class of the asteroidal achondrites.

The meteorite is named after Brachina in South Australia.

[1] The mineral composition of the Brachina meteorite is olivine (80%), plagioclase (10%), Clinopyroxene (5.5%), iron-sulfide (3%), chromite (0.5%), chlorapatite (0.5%) and pentlandite (0.3%) and traces of meteoric iron.

Melt inclusions consist of glass with orthopyroxene and anorthoclase.

The chemical and mineralogical composition is similar to the Chassigny meteorite, but the trace elements are fundamentally different.
