云南镇康马鹿街金矿地质特征与成矿分析

摘要

马鹿街金矿大地构造位置属保山陆块,次级构造单元为保山—镇康地块,属三江成矿带中南段的重要组成部分.对矿区地质特征、矿床地质特征、矿床成因、找矿标志及成矿远景进行深入分析,得出矿床成因属断裂控制的高—中温热液矿床、三叠系上统牛喝塘组三段(T3nh3)玄武岩地层中的断层破碎带具有良好成矿远景的结论,并提出了相应的找矿标志,对下一步地质工作具有十分重要的参考价值.%Geotectonic position of Malu gold deposit belongs to Baoshan block-secondary structural element in Baoshan-Zhenkang region,as is an important part of middle-south section of Sanjiang metallogenic belt.In this paper,the author made an analysis of its geological characteristics of deposit,including the geological characteristics of deposit,the genesis of deposit,the prospecting sign and the metallogenic prospect.It is concluded that the genesis of deposit is controlled by the high-middle temperature hydrothermal deposit.Triassic Shangtang Niutangtang formation (T3nh3) basalt strata will have a good prospect of metallogenic prospecting.He puts forward the corresponding prospecting mark of great reference value for next geological work.
