湖南省渣滓溪锑(钨)矿床金矿化的发现及成矿模型构建

Discovery of Gold Mineralization and Establishment of Minerogenetic Model for Zhazixi Antimony-tungsten Deposit in Hunan Province

渣滓溪锑(钨)矿床位于雪峰弧形锑(钨)成矿构造带中段,成矿条件十分有利.结合最新发现的金矿化特征,对矿床特征进行了总结,并初步建立了矿床成矿模型.结果表明:①矿床类型为中—低温热液充填型锑(钨)矿床;②印支期为区内主要成矿时代,造山运动形成矿床有利的成矿构造;③金、锑成矿物质来源为壳幔混合来源,钨来源于五强溪组围岩,成矿流体水源主要为大气降水.

Zhazixi Antimony-tungsten Deposit is located in the middle of xuefeng arc gold-antimony tungsten metallogenic belt.The metallogenic conditions are very favorable Combined with the newly discovery of the gold mineralization characteristics,the deposit characteristics is summarized,and the minerogenetic model is established.The study results show that:①the deposit type is medium-low temperature hydrothermal filling-type Au-Sb-W deposit;②the indosinian period is the main metallogenic age in the area,orogeny product the favorable mineralization structure;③the metallogenic materials of gold and antimony formed by orogenic movement are the mixed sources of crust and mantle,tungsten comes from the surrounding rocks of Wuqiangxi formation;and the source of metallogenic fluid is mainly meteoric water.
