Thirty percent of the meteorite is the iron-rich metallic phases kamacite and taenite, with the rest mostly made up of olivine. There are minor amounts of other minerals, including several phosphates such as farringtonite (Mg3(PO4)2) and stanfieldite (Ca4(Mg,Fe)5(PO4)6) and merrillite (a member of the whitlockite group).
