Perryite
A nickel silicide of silicon-rich meteorites — first found at Horse Creek and described in 1963.
Intro adapted from Wikipedia (CC BY-SA).
Perryite is an IMA-recognized mineral species in the native element class, with the chemical formula (Ni,Fe)₈(Si,P)₃.
It crystallizes in the hexagonal crystal system (space group R-3c).
Key properties: specific gravity 7.63.
IMA symbol Pry, IMA status: approved, named in 1965.
Found in anomalously silicon-rich mesosiderite and enstatite chondrite meteorites, probably formed by exsolution from kamacite.
It is found associated with Kamacite, troilite, schreibersite (Horse Creek, Kota-Kota meteorites); kamacite, enstatite (South Oman meteorite).
The name refers to Stuart Hoffman Perry (1874–1957), American newspaperman and leading private collector of meteorites, who originally described the Horse Creek meteorite.
