/ˈmækəˌnɔaɪt/

Origin: From a proper name, combined with an English element. Etymons: proper name Mackinaw , -ite suffix¹.

Etymology: < Mackinaw, the name of a mine in Snohomish County, Washington State, U.S.A. + -ite suffix¹.

Mineralogy.

A bronze-coloured tetragonal sulphide of iron and usually nickel in non-stoichiometric proportions, occurring as grains and minute lamellae.

1962 H. T. Evans et al. in Program Ann. Meetings Geol. Soc. Amer. 47A Recently, another iron sulfide mineral, mackinawite, very similar in physical properties, to valleriite, but containing no copper.., has been identified from the Mackinaw Mine, Snohomish County, Washington.

1969 Amer. Mineralogist 54 1190 Information about the occurrence, optical properties, microhardness and cell-size is given for a nickelian mackinawite (Fe 38·1%, Co 3·3%, Ni 18·7%) from Vlakfontein in the Transvaal.

1969 Amer. Mineralogist 54 1190 This mackinawite was examined in reflected light in both air and oil. It shows the very strong pleochroism and anisotropy characteristic of this mineral.

1979 Nature 12 July 134/2 One stage in sedimentary pyrite formation is ‘FeS’+S→FeS₂, where ‘FeS’ represents black precursor sulphides such as amorphous iron sulphides and fine-grained mackinawite (Fe_1+xS).

1992 W. A. Deer et al. Introd. Rock-forming Minerals (ed. 2) 586 Metastable phases such as marcasite, mackinawite (Fe_1+xS) and greigite..may play an important role as precursors for the formation of pyrite.
