摘要
内蒙古浩布高铅锌矿床是比较典型的矽卡岩型矿床。矿区出露的主要地层为海相沉积和陆相–火山沉积岩系的二叠系大石寨组,同时也是浩布高铅锌多金属矿床的主要容矿围岩。通过对该矿床钻孔中不同岩石成矿元素分析,成矿元素As、Zn、Cu、Pb、Sn等在地层围岩(板岩、大理岩、花岗岩等)中均具有相对较高的丰度值,明显地高于克拉克值;且成矿气水热液与地层围岩发生渗滤交代作用,热液在运动的过程中活化围岩中的成矿元素,为矿床的形成提供了一定量的物质来源。
The Haobugao Pb-Zn deposit is a typical skarn deposit in Inner Mongolia. The main strata exposed in the mining area are the Permian Dashizhai Formation of marine sedimentary and continental-volcanic sedimentary rock series, and also the main host rock of the Haobugao Pb-Zn polymetallic deposit. Based on the analysis of ore-forming elements of different rocks in the boreholes of the deposit, the metallogenic elements As, Zn, Cu, Pb, Sn, etc. have relatively high abundance value in the formation surrounding rock (slate, marble, granite, etc.), which are obviously higher than the clark value;The mineralization elements in the surrounding rocks were activated by the hydrothermal fluid and the formation surrounding rock, which provided a certain amount of material source for the formation of the deposit.
