| 摘 要： | 辽西义县是辽宁省主要的萤石矿床产地,萤石产于中元古界长城系-蓟县系碳酸盐岩中.为了研究成矿物质来源及矿床成因,对该矿床进行了Sr同位素研究.萤石的Sr同位素N(87Sr)/N(86Sr)比值为0.708 476～0.708 533,该比值介于赋矿碳酸盐岩Sr同位素比值(0.708 926～0.722 043)和中侏罗统髫髻山组火山岩Sr同位素比值(0.707 584～0.710 382)之间,表明成矿物质主要来源于赋矿围岩和髫髻山组火山岩,结合Sr同位素图解认为其矿床类型属于热液充填交代型. |

| Abstract: | The Yixian fluorite deposit in western Liaoning is an important fluorite-producer in Liaoning Province,with fluorites occurring in carbonate rocks of Mesoproterozoic Changcheng and Jixian System.In order to study the source of ore-forming materials and genesis of fluorite deposit,Sr isotopic composition was studied.The results show that Sr isotope ratios of fluorites range from 0.708 476 to 0.708 533,higher than those of host carbonate rocks of Mesoproterozoic Changcheng and Jixian System and lower than tho... |
