Brahinit

Meteorit NWA 3151

Brahinit je vrsta meteorita iz skupine preprostih ahondritov (kamnitih meteoritov).
Brahiniti imajo ime po meteoritu Brachina, ki so ga našli 26. maja 1974 v puščavi južne Avstralije. Brahiniti so v glavnem sestavljeni iz olivina, avgita, troilita (FeS) in ortopiroksena. Njihova starost je ocenjena na okoli 4,5 milijard let[1] . Od nastanka do danes so doživeli taljenje in rekristalizacijo. Starševsko telo brahinitov še ni znano, verjetno je to asteroid tipa S ali tipa A[2] Podobno kot akapulkoiti so tudi brahiniti nastali iz hondritov.
