Naldrett A.J., Ebel D.S., Asif M., Morrison G. and Moore C.M. Fractional crystallisation of sulfide melts as illustrated at Noril'sk and Sudbury

Статья из журнала Economic Geology Vol. 95, 2000, pp. 889–900 Abstract The Voisey’s Bay Ni-Cu deposit is one of the most significant discoveries made in Canada in the last 30 yr. Known reserves, plus indicated and inferred resources, amount to 136.7 106 metric tons (t), grading 1.59 wt percent Ni and 0.85 wt percent Cu. The deposit can be described in terms of four geologic settings: the Eastern Deeps, consisting of massive and disseminated sulf...

Статья из журнала Mineralium Deposita (1999) 34: 227-240 Abstract Magmatic Ni-Cu sul®de deposits form as the result of segregation and concentration of droplets of liquid sulfide from mafic or ultramafic magma, and the partitioning of chalcophile elements into these from the silicate melt. Sulfide saturation of a magma is not enough in itself to produce an ore deposit. The appropriate physical environment is required so that the sulfide liquid...
