niggliite Min.|ˈnɪglɪaɪt|
[f. the name of Paul Niggli (1888–1953), Swiss mineralogist + -ite1.]
A mineral containing platinum and tin (or perhaps tellurium), found at Insizwa in Cape Province, Republic of South Africa.
1936D. L. Scholtz in Publ. Univ. Pretoria 2nd Ser. i. 184 (heading) Mineral F (niggliite). 1955Amer. Mineralogist XL. 693 Niggliite..was found in a concentrate which was obtained by panning large amounts of oxidized sulphide ore from Waterfall Gorge, Insizwa, South Africa. 1968I. Kostov Mineralogy 115 Various other formulae have been given to niggliite, PtTe, PtSn, and Pt2Sn3; its structure appears to be that of niccolite. 1972Mineral. Mag. XXXVIII. 796 The close similarity of niggliite to synthetic PtTe..led Groeneveld Meijer (1955) to suggest that they were identical. Ramdohr (1960) suggests that the formula is Pt2Sn3 but in Ramdohr (1969) the composition is given as ‘PtTe, perhaps a mixed crystal with isostructural PtSn’. Scholtz..reports that re-examination showed niggliite is essentially PtSn. Ibid. 798 Niggliite from the type locality has been shown to be an antimonian-bismuthian variety of PtSn. |
