Naldrett A.J. World-class Ni-Cu-PGE deposits: key factors in their genesis

Статья из журнала Mineralium Deposita (1999) 34: 227-240Abstract
Magmatic Ni-Cu sulde 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 mixes with enough magma to become adequately enriched in chalcophile metals, and then is concentrated
in a restricted locality so that the resulting concentration is of ore grade.
