    江西钨矿床主要成因类型及找矿潜力分析

    The main genetic types of tungsten deposits and prospecting potential of resources in Jiangxi Province

    • 摘要: 在江西省钨矿资源潜力评价工作的基础上,总结江西钨矿床的主要成因类型,主要有岩浆热液石英脉型、岩体型、斑岩型、矽卡岩型和云英岩型等钨矿床,分别论述各类型典型矿床的地质特征,分析各类型钨矿床找矿方向并预测其资源潜力。共圈定钨成矿远景区13处,运用含矿地质体体积法预测全省各类型钨矿资源潜力,分别为:岩浆热液石英脉型500万吨、岩体型200万吨、斑岩型约16万吨、矽卡岩型350万吨、云英岩型约50万吨。指出江西钨矿的找矿重点,一是赣北地区钨矿成矿规律研究,提出找矿模型; 二是加强深部找矿理论研究,寻找隐伏矿床; 三是深入其它类型钨矿(除石英脉型)研究,特别是最具找矿潜力的大湖塘式岩体——石英脉复合型钨矿和朱溪式矽卡岩型钨铜矿,可作为该区下一步找矿的主攻方向。

       

      Abstract: On the basis of the experience in evaluating work of tungsten resources potential in Jiangxi Province, authors summarized the main tungsten genetic types, which include magmatic hydrothermal quartz-vein type, granite type, porphyry type, skarn type and greisen type. This study describes the geological characteristics of various typical deposits, analyzes exploration strategy, and predicts the resources potential. A total of 13 tungsten metallogenic prospect areas have been determined using volume method of Au-bearing geological masses to predict tungsten ore resource potential in Jiangxi province. The results show that the quartz-vein type deposits contain up to 5 million tons, the granite type to 2 million tons, the granite type about 160 thousand tons, the skarn type to 3.5 million tons, and the greisen type about 0.5 million tons. Key aspects of prospecting tungsten deposits in Jiangxi should focus on(1)studying metallogenic regularity of tungsten mineralization in north Jiangxi and proposing metallogenic models;(2)strengthening study of deep ore-prospecting theory so as to explore hidden orebodies; and(3)deepening study of other tungsten-bearing deposit types(except quartz-vein type), especially the most prospecting potential type deposits such as Dahutang-type rock-quartz vein type tungsten deposit and Zhuxi skarn-type tungsten and copper deposit, which can be the key direction of future prospecting.
