| 摘 要： | 文章简述了岩浆型Cu—Ni—PGE硫化物矿床的主要特点和研究现状，探讨了矿床的成矿机制，认为其成矿的首要条件是岩浆中硫达到饱和而使硅酸盐岩浆与硫化物熔体发生熔离。综述了如何利用同位素方法确定其成矿物质来源，介绍了如何判别硫饱和度的方法。 |
| 关 键 词： | 地质学 岩浆作用 熔离作用 Cu—Ni—PGE矿床 铼-锇同位素 硫的饱和状态 综述 |

| Abstract: | Magmatic Cu-Ni-PGE sulfide deposits, the major supply sources of nickel and PGE in the world market, are considered to be spatially associated with mafic-ultramafic rocks. To meet the increasing demand for Cu, Ni and Pd, it is necessary to strengthen the research work on this type of ore deposits. In this paper, some important problems concerning magmatic copper-nickel sulfide deposits are discussed, with the emphasis placed on their metallogenic mechanism. It is generally believed that sulfide saturation and segregation from silicate magma as well as the corresponding favorable structural environment play a key role in their formation. In addition, the Re-Os isotopic system as a tracer of sulfide ore formation and the geochemical indexes for measuring the condition of sulfur in magma are also discussed. |
