The Brachina meteorite is the type specimen of the
asteroidal achondrites
.
Naming and discovery
The meteorite is named after
Brachina in South Australia. Two fragments (total 200 g) were found by B.M. Eves at 31°18′00″S 138°23′00″E / 31.300000°S 138.383333°E on 26 May 1974.[1]
Description
The mineral composition of the Brachina meteorite is
Chassigny meteorite, but the trace elements are fundamentally different.[2]
Parent body
Melt inclusions indicate that there were melting processes active on the brachinite parent body.[2]
Classification
The meteorite was classified as a
chassignite in 1978,[3] but in 1983 trace element analysis showed that the Brachina meteorite was fundamentally different from Chassigny. It was therefore proposed that the meteorite should be the type specimen of a new meteorite class, the brachinites.[2] This classification has remained valid since then.[1][4]
