| 摘 要： | 东昆仑是当前成矿研究的热点区域,前人对该地区做了大量的成矿学与构造学研究1-2],但对区域内的矿物以及矿区围岩的化学元素、微量元素等的研究不够精细。为进一步认识矿区与区域矿物特征,分析矿区成矿作用,通过对矿区矿物的标本观察,偏光显微镜观察,等离子体质谱仪分析等,对东昆仑野马泉矿区围岩的蚀变、化学元素、微量元素和矿区的矿物特征、化学元素、微量元素进行研究。结合前人研究成果,认为,该地区成床主要成矿物质来源为早古生代在祁漫塔格地区形成的一套由变质橄榄岩、堆晶杂岩、中酸性火山岩、硅质岩、碳酸岩等构成的岩石组合;野马泉地区主矿区的成矿类型为层控型热液反应改造型矿床;成矿元素Zn、Co、Ni、Cr、Ti等含量均高出地壳的丰度值。

| Abstract: | Eastern Kunlun which was studied with metallogeny and tectonics by predecessors is hot spot region of research on mineralization. While research on the minerals in region as well as the chemical elements and trace elements in surrounding rock isn＇t elaborate. To study the mineral characteristics and analyse metallogenesis, chemical and trace elements and other characteristics of surrounding rock and mining area in YeMaQuan were researched through methods of mineral specimen observation, polarized light microscopy observation and Plasma mass spectrometer analysis etc. Combined with previous research results, following conclusions could be gotten： Major ore-forming materials in the region are the rock association of Qimantage area including metamorphic peridotite, cumulate diamictite, intermediate-acidic volcanic rocks,siliceous rock and carbonatite in early paleozoic; Metallogenic type of the main field in YeMaQuan is stratabound hydrothermal reaction renovation deposit; Value of Partial metallogenic elements including Zn、Co、Ni、Cr、Ti is higer than crust abundance value. |
