pyroxferroiten.

Brit.

/ˌpʌɪrɒksˈfɛrəʊʌɪt/, U.S.

/ˌpaɪrɑksˈfɛroʊˌaɪt/

Origin: Formed within English, by derivation. Etymons: pyroxene n., ferro- comb. form, -ite suffix¹.

Etymology: < pyrox- (in pyroxene n.) + ferro- comb. form + -ite suffix¹, after pyroxmangite n.

Mineralogy.

A rare, yellow silicate mineral of the pyroxenoid group, originally found in lunar rock samples and later in terrestrial gabbroic rocks.Pyroxferroite, (Fe,Mn,Ca)SiO₃, is an iron-rich analogue of pyroxmangite. Crystal system: triclinic.

1970 E. C. T. Chao et al. in Proc. Apollo 11 Lunar Sci. Conf. I. 65 Pyroxferroite was first recognized by the LSPET (1969) as an unidentified yellow mineral that seemed to be concentrated in vuggy areas of the Type B rock.

1970 E. C. T. Chao et al. in Proc. Apollo 11 Lunar Sci. Conf. I. 75 Lindsley (1967) recently synthesized pyroxferroite of composition Ca_0·15Fe_0·85SiO₃ at pressures from 10 to 17·5 kbar and temperatures from 1130 to 1250°C.

1973 C. A. Sorrell & G. F. Sandstrom Rocks & Minerals of World 60 The major lunar minerals are calcic plagioclase..and pyroxene... Common are olivine..and pyroxferroite, CaFe₆(SiO₃)₇, a new mineral similar to the pyroxenes.

1996 Geochimica & Cosmochimica Acta 60 4562 Pyroxene cores have nuclei of magnesian pigeonite mantled by augite, in turn rimmed by strongly zoned ferroan pigeonite, with outer rims of pyroxferroite.
