nesquehonite Min.|nɛskwiːˈhəʊnaɪt| [f. Nesquehon-ing (see quot. 1890) + -ite1.] Magnesium carbonate trihydrate, MgCO3.3H2O, found as colourless monoclinic crystals.
1890Genth & Penfield in Amer. Jrnl. Sci. CXXXIX. 122 The clear crystals..proved on examination to be a new mineral, having the composition MgCO3.3H2O, to which we have given the name Nesquehonite, after the locality where the mineral was found, the Nesquehoning Mine being one of the best known in Pennsylvania. 1934Mineral. Abstr. V. 431 Galleries in the Cogne magnetite mine in serpentine rocks, at an elevation of 2500 metres in the Piedmontese Alps, have a constant temperature of 4°C., and this has favoured the formation of lansfordite..and nesquehonite. 1957G. E. Hutchinson Treat. Limnol. I. x. 665 At ordinary temperatures the carbonate that precipitates when saturation is reached at from 10-3 to 10-1 atm. of CO2 is MgCO3.3H2O, or nesquehonite. 1971Contrib. Mineral. & Petrol. XXXIII. 88 The ‘cauliflower’ crusts mainly consist of hydromagnesite and/or nesquehonite with traces of monohydrocalcite and calcite. |
