河南省光山县千鹅冲铜矿床位于东秦岭—大别山钼成矿带上,为我国著名的秦岭多金属成矿带的组成部分.文章对光山县千鹅冲铜矿床地质特征、控矿构造以及找矿标志进行了综合分析、研究,认为千鹅冲铜矿床赋存在泥盆系南湾组变质岩地层中,铜—商大断裂带尤其是近东西向和近南北向的脆性断裂带是其主要控矿构造,九架岭隐伏岩体为本区成矿提供了物质来源,总结了该区的次级断裂构造、物化探综合异常区、矿化组合等一系列找矿标志.为大别山地区寻找千鹅冲式铜矿起到借鉴作用.

Qian'echong copper deposit in Henan Guangshan, located in the eastern Qinling and Dabie orogenic belt, is an important part of Qinling polymetallic mineralizing belt. In this paper,the geological features of Qian'echong copper deposit, ore-controlling factors and ore-searching criteria are investigated. it is realized that,Qian'echong copper deposit hosted in the Nanwan Formation metamorphic rocks of Devonian, the econdary faults,especially the last east-west and north-south brittle fault zones,which belong to Tong-Shang fracture belt are the most important ore-controlling structure,the ore-forming materials mainly come from the Jiujialing concealed rock body,the author discussed some important ore indicators ,such as the secondary faults,geophysical and geochemical anomaly,mineral assemblage.Those ore indicators should be make use for reference in Dabieshan area for Qian'echong-type copper deposit rospecting.
