nordmarkiten.

Brit.

/ˈnɔːdmɑːkʌɪt/, U.S.

/ˈnɔrdmɑrˌkaɪt/

Origin: Of multiple origins. Partly from a proper name, combined with an English element. Partly a borrowing from German Etymons: proper name Nordmark , -ite suffix¹; German Nordmarkit.

Etymology: In sense 1 < Nordmark, the name of an area in Sweden + -ite suffix¹ (see quot. 1868 at sense 1). In sense 2 < German Nordmarkit (W. C. Brögger 1890, in Zeitschr. f. Kryst. u. Mineral. 16 i. 55) < Nordmark , the name of an area near Oslo in Norway + -it -ite suffix¹.

1. Mineralogy. A brown variety of staurolite rich in manganese.

1868 J. D. Dana Syst. Mineral. (ed. 5) v. 389 Manganese-Staurolite, Nordmarkite..; from dolomite in Nordmark, Sweden... Its easy fusibility is reason for here giving this variety the distinctive name Nordmarkite.

1968 I. Kostov Mineral. 289 Staurolites rich in manganese are termed nordmarkite.

1990 W. L. Roberts et al. Encycl. Minerals (ed. 2) 615/1 Nordmarkite = variety of staurolite rich in manganese.

2. Geology. A syenite composed mainly of microperthite, with lesser amounts of quartz and usually oligoclase and biotite, and characterized by a trachytoid or granitic texture.

1892 Amer. Naturalist 26 417 The brown granite is an eleolite–syenite... In chemical composition it is quite like nordmarkite.

1928 Mineral. Abstr. 3 498 The differentiation of the Lung Wang Miao åkerite has given rise to a whole series of granitic derivatives: nordmarkite, alkali-granite-aplite, and quartz-porphyry.

1970 Meddelelser om Grønland 190 ii. 15 The nordmarkites are grey or fawn in colour and are fairly coarse-grained rocks.

1993 Econ. Geol. & Bull. Soc. Econ. Geol. 88 1832/2 The same authors reported initial ⁸⁷Sr/⁸⁶Sr ratios of 0.705 to 0.707 for the Nordmarkite and related intrusive rocks.
