larnite Min.|ˈlɑːnaɪt|
[f. Larne, the name of a town in Co. Antrim, N. Ireland + -ite1.]
A mineral consisting of a metastable monoclinic phase of dicalcium silicate, Ca2SiO4.
1929C. E. Tilley in Mineral. Mag. XXII. 79 Next in importance to spurrite comes a mineral consisting of calcium orthosilicate. As this is the first recorded natural occurrence of this compound it is proposed to designate it as larnite, from Larne, in the vicinity of which these contact minerals occur. 1950Ibid. XXIX. 182 Both the nagelschmidtite and larnite phases have been seen in slags. 1957Amer. Mineralogist XLII. 384 The larnite zone is very prominent, forming a band about thirty inches thick, dark grey to almost black in color, hard, flinty, and very tough. The dark color is..due to..the presence of a small amount of very fine-grained magnetite. Pure larnite is presumably white. 1966[see bredigite]. |
