内蒙古西乌旗博和铜多金属矿地质特征及找矿标志

研究区位于华北板块与西伯利亚板块之间的碰撞接壤部位,区域岩浆活动频繁,褶皱、断裂构造发育,具有良好的成矿地质条件。本文以现有成果资料为依托,充分分析研究区成矿地质背景、地球物理及地球化学特征,并着重研究了区内侵入岩岩体地质特征,论述了该区铜矿体的矿体地质特征,探讨了矿体的成因类型,总结了区内铜矿体的找矿标志。综合分析认为本区矿体成因为与构造有关的中温热液型铜矿床,研究区具备较好的找矿前景,对该区进一步开展找矿工作提供了参考。

Metallogenic characteristics and prospecting criteria of copper polymetallic deposit in Xiwu Banner Bohe area,Inner Mongolia

The study area is located on the collision border between the north China plate and the Siberian plate.Magmatic activity is frequent and fold fault structure is developed in the area,so it has good metallogenic conditions of forming deposits. Based on the available data, this paper fully analyzes the geophysical and geochemical characteristics and the metallogenic geological background in the study area, and studies the geological characteristics of intrusive rock mass in the area emphatically. Besides,it discusses the geological characteristics of ore body of copper deposit in this area and the genetic type of ore body, and summarizes the prospecting marks of copper deposits in the area.It is concluded that the ore body in this area is formed by the middle temperature hydrothermal copper deposit related to structure, and that the study area has a good prospecting prospect,which provides evidence for more prospecting work in this area.
