云南宁蒗地区铜厂河铜矿构造控矿规律研究
STUDY ON OREBODY’S STRUCTURE CONTROLLING LAW OF TONGCHANGHE COPPER DEPOSIT IN NINGLANG AREA, YUNNAN PROVINCE
【摘要】 宁蒗地区铜厂河铜矿主干控矿构造为 SN向断裂体系 ,起着导矿、配矿、容矿的作用。矿区 NWW向 F1 断裂为阻矿构造 ,铜矿化均产于其下盘 (南盘 ) ;NE向 F2 ,F3断裂将本区分成三个不同矿化特征的矿段 ,其东、中矿段是寻找隐伏 -半隐伏铜矿体的有利地段。由于构造活动的多期次和构造形变的分带性 ,矿区铜矿具显著的成矿多期、多阶段性和矿化体水平 -垂直分带性规律。
【Abstract】 In Tongchanghe mining district of Ninglang area, orebodies are controlled by NS trending fault system which plays roles of ore canal, ore accommodation and ore allotment. Copper orebodies resided on lower wall (southern wall) of NWW trending fault F 1 in mining district. And the mining district is divided into three different mineralized section by NE trending fault F 2 and F 3,and the eastern and the middle are favorable sections for blind orebody exploration. The copper deposit in study area possesses multi minerogenetic stages and orebody spatial zonation because of tectonic pulse activity and structural deformation zoning.
