| 摘 要： | 烟筒砬子矿床是吉林省东部新发现的铂铜矿床之一,其矿床特征国内外研究鲜有提及。通过对吉林省烟筒砬子铂铜矿床的地质特征、矿物学、矿相学以及电子探针分析发现,矿体主要赋存在辉长岩与五道沟群浅变质岩的内接触带,热液交代作用形成的石榴石化辉长岩是其主要赋矿围岩,由此认为热液交代对铂族元素富集成矿起到了决定性作用。

| Abstract: | Yantonglazi deposit is one of the newly discovered Ni-Cu-PGE sulfide deposits in eastern Jilin province,and its characteristics are seldom mentioned at home and abroad.We analyzed geological features,mineralogy,chalcography,and electron probe of Yantonglazi PGE-Cu deposit,the results indicate that ① the orebody occurs mainly in the inner contact belt between gabbro and the epi-metamorphic rock of Wudaogou group;and ②the wall rock is the garnetized gabbro formed by hydrothermal metasomatism.This article comes to a conclusion that the hydrothermal metasomatism is a crucial factor for metallization. |
