本文通过野外调研、岩心编录、分析测试、综合研究等方法,系统总结了下庙前金矿区地质特征、矿体特征及矿石特征,认为区内构造以NE向逆冲推覆型韧性剪切带为主,金矿化受韧性剪切带控制,浅部金矿体产于韧性剪切带内碎裂石英脉、硅化破碎带中,深部见糜棱岩型金矿体,成矿类型属韧性剪切带型金矿.并指出韧性剪切带中深部缓倾部位、韧性剪切带与燕山期花岗斑岩耦合部位是最有价值的找矿方向,有必要开展进一步找矿验证.
Geological characteristics and prospecting direction of Xiamiaoqian gold Deposit in Chongren County,Jiangxi Province
In this article,through field survey,core logging,analysis and comprehensive research methods,summarized the temple gate under gold mine geological characteristics,ore body characteristics and ore features,think zone structure in NE to thrust nappe ductile shear zone type is given priority to,the gold mineralization controlled by the ductile shear zone and shallow gold orebody in ductile shear zone cataclastic quartz veins,silicified fracture zone,Mylonite gold orebodies are found in the deep,and the metallogenic type belongs to ductile shear zone type gold deposit.It is pointed out that the most valuable prospecting directions are the slow dip part in the middle and deep ductile shear zone and the coupling part between ductile shear zone and Yanshanian granitic porphyry.It is necessary to carry out further prospecting verification.
