A nickel-rich mineral also containing silicon and phosphorus that is reported to have been found in several meteorites.
1965Fredriksson & Henderson in Trans. Amer. Geophysical Union XLVI. 121/2 The Horse Creek, Baca County, Colorado, iron meteorite, found in 1937, is unique for four reasons:..(4) this iron contains about 3% of Perryite, nickel silicide, a new mineral... The approximate chemical composition of Perryite is Ni 81%, Si 12%, Fe 3% and P 5%. 1968Mineral. Mag. XXXVI. 852 The South Oman enstatite chondrite also contains perryite, but its abundance is much less than in Kota-Kota... In this meteorite, perryite occurs as small laths, usually associated with kamacite. 1970Geochim. et Cosmochim. Acta XXXIV. 169 Electron-microprobe analysis of Si, P and Ni in the metal grains and associated schreibersite and perryite of eight enstatite achondrites shows that the compositions of these phases are relatively constant within a given meteorite, but show substantial variations between meteorites. |
