Naming and history [ edit ]
Brachinites are named after the Brachina meteorite , the type specimen of this group, which in turn is named after Brachina , South Australia .[1]
Description [ edit ]
Brachinites consist almost entirely of olivine (74 to 98% by volume). Other minerals include plagioclase (6.7 to 12.9%), iron sulfides (1.8 to 4.0%), clinopyroxene (1.5 to 8.2%) and orthopyroxene (0 to 2.4%). Trace minerals include phosphates and meteoritic iron . The only deviation from chondrites is the very high olivine/orthopyroxene ratio.[2]
Specimens [ edit ]
As of 2022, there were 56 meteorites classified as brachinites.[3] Brachina meteorite .
