内蒙古长胜渠金矿地质特征及勘查方向

Geological characteristics and exploration direction of Changshengqu gold deposit,Inner Mongolia

长胜渠金矿位于乌拉山-集宁铁-金成矿带上,成矿严格受构造控制,属岩浆热液矿床。在研究前人勘查资料的基础上,从矿区地质、围岩蚀变、矿体特征、矿石特征几个方面总结了矿床地质特征,分析了矿床控矿因素,为下一步勘查工作提出了建议。认为其主要控矿因素为北西西-南北向弧形断裂构造、燕山期岩浆活动以及乌拉山群。提出在已发现矿体深、边部有较大找矿潜力,高精度遥感构造解译可作为下一步勘查工作的重要辅助手段。

Changshengqu gold deposit is located in Wulashan-Jining iron-gold metallogenic belt,which is strictly controlled by structure and belongs to magmatic hydrothermal deposit.On the basis of previous exploration data,this paper summarizes the geological features of the deposit from the aspects of mining area geology,wall rock alteration,ore body characteristics and ore characteristics,analyzed the ore control factors of the deposit,and provided forward suggestions for the next exploration work.It is considered that the main ore controlling factors are NWW-NS trending arc fault structure and Yanshanian magmatic activity and Wulashan Group.It is proposed that there is a great prospecting potential in the depth and edge of the discovered ore body,and high-precision remote sensing structural interpretation can be an important auxiliary means for the next exploration work.
