General characteristics of fluid inclusions in magmatic Ni-Cu-PGE sulfide deposits

摘要

1 IntroductionMagmatic Ni-Cu-platinum group element(PGE)ores result from liquid immiscibility between sulfide and silicate magmas(Naldrett, 1989); however, it is clear that hydrothermal processes also play a role in PGE and base-metal. especially Cu enrichment in some magmatic ore deposits (Watkinson, 1990; Farrow, 1994). The purpose of this paper is to evaluate the possible role of fluids in enrichment of copper, nickel and PGE.
