| 摘 要： | 喀拉通克Ｙ１含矿岩体岩石类型属铁质基性岩类，岩体为单式岩体，具富镁、铁、碱、低钙贫铝的特点。组成岩体的各岩相是同一母岩浆结晶分异的产物。原始岩浆为来自上地幔的拉斑玄武岩浆。岩体锶初始比值约为０．７０３３，形成时代约为２９１Ｍａ。在岩浆结晶分异作用下，氧化物组分的变化使硫化物熔浆与硅酸盐熔浆发生分离，并在重力作用下聚积形成铜镍硫化物富矿。

| Abstract: | This Paper discusses comprehensively on the geochemistry characteristics and their relationship to the metallogeny of rockbody No. Y1 at Kalatongke. The results indicate that: (1 ) The rockody is characterized by richness in Mg, Fe and alkaline, and by lowness or poorness in Ca and Al. It belongs to ferrobasic rock type; (2) The rockbody is single (not a complex ). Its petrofacies are the result of magmatic crystallization and differentiation in the same mothrer magma; (3) Its initial magma is of theleiitic character, and the primary strontium ratio is about 0. 7033. The rockody is formed about at 271 Ma; (4 )The major factor which causes differentiation of the sulfide melt from the silicate melt is the content change of oxides in melt with the magmatic crystallization and differentiation when the physical and chemical condition changes .and the major factor of cumulation of sulfide melt to the extent of rich orebody is gravity process. |
