| 摘 要： | 在内蒙古固阳县文圪乞镁铁质—超镁铁质岩体中发现了砷铂矿、砷锑钯矿和黄碲钯矿等铂族金属矿物。野外观察和室内电子探针分析发现,砷铂矿与磁铁矿、绿泥石共生,砷锑钯矿和黄碲钯矿与黄铁矿共生。铂族金属主要赋存在二辉石岩中,且在镁铁质—超镁铁质杂岩体中呈脉状产出。文圪乞铂族金属的分布、产状及特征显示岩浆作用对铂族金属的富集起着关键的控制作用,岩浆期后的热液作用对铂族金属迁移、富集也起着关键作用。

| Abstract: | Three kinds of platinum group minerals(PGMs) are found in the Wen'geqi mafic-ultramafic complex in Guyang County,Inner Mongolia.They are sperrylite which occurs together with magnetite and chlorite,and mertieite and kotulskite which occur together with pyrite.Based on field observations and electron microprobe analysis,PGMs mainly occur in websterite,and the websterite is distributed in mafic-ultramafic complex as a dike.The distribution,occurrence and characteristics of PGMs in the Wen'geqi mafic-ultramafi... |
