克什克腾旗某银多金属矿床找矿方向

Prospecting Direction of a Silver Polymetallic Deposit,Hexigten Banner

内蒙古克什克腾旗某银多金属矿为超小型中低温热液充填型矿床,严格受近EW向的压扭性断裂构造控制,矿体赋存在下元古界宝音图群片麻岩及闪长岩中。在对该区地质特征分析的基础上,通过与周边相邻的已探明矿床的地质特征进行综合对比,系统分析了该多金属矿床地质特征,讨论了矿床成因和找矿标志,并进一步对该地区的找矿方向进行了探讨,提出近SN、NW向的主要赋矿构造,为下一步勘查工作的重点和主攻方向。

The silver polymetallic deposit of Inner Mongolia Hexigten Banner belongs to a super small medium low temperature hydrothermal filling deposit,is strictly controlled by EW compression shear fracture structure,and the orebody exists in gneiss and diorite of Lower Proterozoic Baoyintu group.Based on analyzing the geological characteristics of the mining area,the geological features of the polymetallic deposit is discussed systematically by conducting comprehensive comparison on geological characteristics of the polymetallic deposit and its adjoining the proven mineral deposits,the genesis and prospecting marks of the polymetallic deposit are analyzed,besides that,the prospecting direction of the mining area are also discussed,the focus of the next exploration and prospecting direction are the nearly EW and NW major ore-occurrence structures.
