香炉山钨矿床是江南造山带钨成矿带中部一个典型的矽卡岩型钨矿床,矿体主要赋存于寒武系杨柳岗组的不纯灰岩和燕山晚期黑云母花岗岩的接触带附近.白钨矿是香炉山钨矿床最主要的矿石矿物,其微量元素和稀土元素特征常用来研究成矿流体的演化和成矿环境.文章以香炉山钨矿床不同类型的白钨矿为研究对象,进行了原位微区(EMPA和LA-ICP-MS)分析,对不同类型白钨矿中元素的分布规律和成矿流体的性质及演化进行了探讨.
Geochemical Characteristics of Xianglushan Scheelite and Its Indicative Significance
The Xianglushan tungsten deposit is a typical skarn-type tungsten deposit in the middle of the tungsten metallo-genic belt of the Jiangnan orogenic belt,and the ore body is mainly found near the contact zone between impure limestone and late biotite granite of the Cambrian Yangliugang Formation.Scheelite is the most important ore mineral in the tungsten deposit of Xianglushan,and its trace element and rare earth element characteristics are often used to study the evolution of mineralizing fluids and the mineralization environment.In this paper,different types of scheelite in the tungsten deposit of Xianglushan were used as the research object,and in situ micro-region(EMPA and LA-ICP-MS)analysis was carried out,and the distribution law of elements and the properties and evolution of mineralizing fluids in different types of scheelites were discussed.
