The higher phosphide barringerite, (Fe,Ni){sub 2}P, has been found in a thin section of the Y-793274 lunar meteorite. This meteorite originated from a highlands/mare boundary and contains mare and highlands components in a 2:1 ratio. The original report of barringerite was from the Ollague pallasite; however, there is uncertainty where the barringerite in this pallasite may have formed terrestrially. Terrestrial weathering or artificial heating as the source of the barringerite in the lunar meteorite can be excluded. Therefore, Y-793274 seems to contain the first unambiguous extraterrestrial occurrence of barringerite.
