schreibersite Min.|ˈʃraɪbəzaɪt|
[Named after von Schreibers, of Vienna.]
†a. A chromium sulphide, Cr2S3, supposed to have been found in a meteorite. Obs.
1846C. U. Shepard in Amer. Jrnl. Sci. LII. 383 Schreibersite, (Shepard).—Named in honor of the late Carl von Schreibers, Director of the Imperial Cabinet at Vienna, and a well known author on meteorites.
b. A strongly magnetic phosphide of iron and nickel, (Fe,Ni)3P, usu. with small amounts of cobalt, that is present in iron meteorites and forms lustrous white tetragonal crystals that tarnish to yellow or brown. Cf. rhabdite 3. [ad. G. schreibersit (A. Patera 1847, in Österreichische Blätter f. Lit. und Kunst 23 July 694/2).]
1849Amer. Jrnl. Sci. LVIII. 440 Something..similar is found in the meteoric iron of Arva. Patera was enabled to collect a sufficient quantity of it to make three analyses... As Berzelius had given no name to this substance, Haidinger, in concurrence with M. Patera, proposed for it the specific name of Schreibersite. At a subsequent session..Haidinger..says he has since learned that the American mineralogist and chemist, Prof. Shepard,..had given..this same name to a mineral, also of meteoric origin, which occurs in small brown striated prisms in the meteoric stone of Bishopsville, S.C., which fell in March, 1843... Haidinger.. would be pleased to continue the name of Schreibersite to the Arva Species, and would propose for Shepard's new species, the name of Shepardite. 1868Lockyer Elem. Astron. §318 Besides these substances, a compound of iron, phosphorus and nickel, called schreibersite, is generally found: this compound is unknown in terrestrial chemistry. 1968Jrnl. Geophysical Res. LXXIII. 6963/2 The most notable feature of schreibersite is its compositional variability. 1975Sci. Amer. Feb. 35/1 At 1,294 degrees gaseous molecular phosphorus reacted with the surface of the metal grains, thus forming the mineral schreibersite. 1977A. Hallam Planet Earth 27/3 Other highly significant features which must be explained are the presence within some tektites of minute grains of the meteoritic minerals kamacite, troilite and schreibersite, [etc.]. |
