Barringerite
Barringerite is an IMA-recognized mineral species in the native element class, with the chemical formula (Fe,Ni)₂P.
It crystallizes in the hexagonal crystal system (space group P-62m). It is a member of the Barringerite structural group.
Key properties: Mohs hardness 7; specific gravity 6.92.
IMA symbol Bgr, IMA status: approved, named in 1968.
Along the contacts between schreibersite and troilite in a Fe–Ni meteorite (Ollague); as a single grain in a brecciated lunar meteorite of mixed mare and highland origin (Y-793274 meteorite).
It is found associated with Kamacite, olivine, schreibersite, troilite (Ollague meteorite); plagioclase, glass (Y-793274 meteorite) schreibersite, wüstite.
The mineral was named to honor Daniel Moreau Barringer (1860–1929), early proponent of the meteor impact origin of Meteor Crater, near Canyon Diablo, Arizona, USA.
