摘　　要：铜华山‒彩华沟地区在过去的调查中积累了丰富的地质、物探、化探等资料,相继发现的忠宝钨矿、彩虹铜矿、天彩金矿等及周边的金铜矿床使该区的找矿工作进入到一个新的勘查和开发阶段,成为找矿的一个热点区。本文在充分收集研究以往地质资料的基础上,通过1∶50000地面高精度磁测扫面,圈定物探异常,对铜华山‒彩华沟地区内具有重要意义的物探异常进行初步查证,圈定找矿靶区,加强该区成矿地质背景和成矿条件、控矿因素及矿化富集规律的综合研究,对区内的找矿远景进行综合评价,认为铜华山钴多金属矿、彩华沟含铜硫铁矿、天彩金矿成矿地质条件有利,成矿元素组合好,找矿标志明显,有与矿致异常特征相似的物化探异常存在,矿产资源潜力较大。Abundant geological,geophysical and geochemical data have been accumulated fromexplorations in the Tonghuashan-Caihuagou area in the past.The discovery of the Zhongbao tungsten deposit,the Caihong copper deposit and the Tiancai gold deposit in the area,including gold-copper deposits in the surrounding area has made it a hot spot for a new round of exploration and development.On the basis of fully collecting and studying the previous geological data,this paper delineates the geophysical anomalies through 1∶50000 high-precision ground magnetic survey,carries out preliminary verification on the geophysical anomalies of great significance in the Tonghuashan-Caihuagou area,delimits the prospecting targets,and strengthens the comprehensive research on the metallogenic geological background,metallogenic conditions,ore-controlling factors and mineralization enrichment law in thearea,and makes a comprehensive evaluation oftheore-prospecting potential in the area.It is concluded that the Tonghuashan cobalt polymetallic deposit,the Caihuagou copper-bearing pyrite deposit and the Tiancai gold deposit have favorable metallogenic geological conditions,good ore-forming element associations,remarkable prospecting signs,geophysical and geochemical anomalies similar to mineralized anomalies,and great resource capacities.
