Localities

At the Yamato 793274 Lunar meteorite, Queen Fabiola Mts, Queen Maud Land, Eastern Antarctica, Antarctica, barringerite was found as a single grain in a brecciated lunar meteorite of mixed mare and highland origin. It was associated with plagioclase and glass (HOM).

At the type locality, the Ollagüe meteorite, Ollagüe, Nor Lípez Province, Potosí, Bolivia, barringerite occurs as bands 10 to 15 microns wide and several hundred microns long; they consist of individual grains less than 1 micron in diameter, occurring along the contacts between schreibersite and troilite in an iron–nickel meteorite. Associated minerals include kamacite, olivine, schreibersite and troilite (AM 55: 317-323, HOM).

At the Canyon Diablo meteorite, Meteor Crater area, Coconino County, Arizona, USA, barringerite is associated with schreibersite, wüstite and lawrencite (HOM).
