✦ Synopsis

New occurrences of the phosphates sarcopside/graftonite (Fe, Mn)a(POa) 2, farringtonite (Mg, Fe)a(P04) 2, and brianite Na2CaMg(P04) 2 in iron meteorites are reported. The sarcopside in Duel Hill (1854) (IVA-Anom) contains less than 0.1 mole % Mna(P04) 2 and more nearly approaches the Fe-rich end member than does any previously reported natural occurrence. This identification of farringtonite in Barranca Blanca (IIE) is the first report of this mineral in a meteorite group other than the pallasites.
