Carletonmooreite
Carletonmooreite is an IMA-recognized mineral species in the native element class, with the chemical formula Ni₃Si.
It crystallizes in the cubic crystal system (space group Pm-3m).
Key properties: specific gravity 7.89; Metallic luster.
IMA symbol Cmo, IMA status: approved, named in 2018.
Localized on plessite fields in aubrite metal nodules in a meteorite, probably formed by low-temperature epitaxial growth by solid-state diffusion from kamacite on tetrataenite.
It is found associated with Low-Ni iron (kamacite), schreibersite, nickelphosphide, perryite, aubréelite, tetrataenite, taenite, graphite.
The mineral was named to honor Carleton B. Moore, chemist and geologist, and founding director of the Center for Meteorite Studies, Arizona State University.
