| 中文摘要:Cu-Ni-PGE矿床绝大多数赋存在基性超基性岩岩体内部，在成因上主要与岩浆结晶分异熔离作用有关，岩浆期后或者独立的热液对于矿床的形成往往起叠加富集的作用。但在四川杨柳坪矿区，除了一般岩浆结晶分异熔离作用形成的Cu-Ni-PGE矿体之外，新近还发现存在独立的完全由热液形成的Cu-Ni-PGE矿体，矿体赋存在基性超基性岩体之外的大理岩片岩中，与基性超基性岩没有直接的关系，矿石品位很高，而且已经成为首要的开采对象。考虑到这样的富矿体在国外文献中鲜有报道，本文介绍其地质概况及初步的研究结果。 |

| Abstract:Most of the Cu Ni PGE deposits are hosted within basic ultrabasic magmatic bodies and originally related to magmatic differentiation and crystallization. Hydrothermal solution evolved from magmatism or directly from mantle usually enriches the disseminated ores originated from magmatic mineralization by superimposition. However, in the Yangliuping area, Sichuan Province, besides the orebodies hosted within basic ultrabasic magmatic bodies, there also exist independent Cu Ni PGE orebodies, which were formed by hydrothermal replacement and hosted within limestone and shale instead of within magmatic rocks. The ores from these orebodies have been mined and smelted because of their high grades of copper and nickel. This paper describes the general geology and origin of the enriched Cu Ni PGE orebodies in Yangliuping, whose significance lies in the fact that such kinds of independent hydrothermal orebodies have not been reported in China. |
