narsarsukite Min.|nɑːsɑːˈsʊkaɪt| [f. Narsarssauk, -suk, name of a plain in SW. Greenland + -ite1.] A silicate and fluoride of sodium, iron, and titanium, Na2(Ti,Fe)-Si4(O,F)11, which is found as yellow tetragonal crystals.
1900G. Flink in Meddelelser om Grønland XXIV. 154 The new mineral..was the first that attracted my attention on Narsarsuk. None of the other new minerals has been found at so many different localities on the plateau or is so largely distributed there. It may therefore, more than any other mineral, be said to be characteristic of the place. On this ground I propose for it the name narsarsukite. 1935Amer. Mineralogist XX. 598 The narsarsukite was seen only in the quartz veins in the roof rock and upper part on the intrusive. 1968I. Kostov Mineral. ii. 300 Baotite is a typical example of silicates with tetragonal rings of silicon tetrahedra [Si4O12]. Narsarsukite has similar rings but they are not isolated as in baotite but linked together along the tetragonal axis in a tube-like manner. |
