摘要
瓦庙坡铜矿位于新太古代—元古宙中条“人字型”三叉裂谷的南东支—王屋山断隆带内,系中条山铜成矿带的东延部分。为探明该区域的找矿前景,在前人研究的基础上,对瓦庙坡铜矿区域地质背景、矿区地质特征、成矿地质条件及其他条件进行分析。结果表明:①赤山沟组下段为区内重要的矿源层;②中条期富含Cu质中基性岩浆活动,为成矿提供了丰富的矿源、热能和动力;③断裂、皱褶及层间剥离断层为区内主要容矿、控矿构造,矿体呈似层状、透镜状分布;④瓦庙坡铜矿为火山、次火山沉积—再改造型铜矿床,矿化以细脉—浸染状、网脉状、星散浸染状以及团块状矿石为主。综合分析认为,瓦庙坡铜矿成矿与地层、构造、岩浆岩关系密切,为多种因素综合形成的火山、次火山沉积—再改造型铜矿床。
The Wamiaopo copper deposit is located in the southeast branch of the Neoarchean-Protero⁃zoic Zhongtiao character trifurcate rift-Wangwushan fault uplift belt,which is the east extension of Zhong⁃tiaoshan copper metallogenic belt.In order to explore the prospecting prospect in this region,based on previ⁃ous research results,the regional geological background,geological characteristics,metallogenic geological conditions and other conditions of Wamiaopo copper deposit are analyzed.The results show that:①The low⁃er part of Chishangou Formation is an important source bed in the region.②The intermediate stage is rich in Cu intermediate basic magmatic activity,which provides a rich source of ore,heat and power for mineraliza⁃tion.③Faults,folds and interlayer detachment faults are the main ore-bearing and ore-controlling structures in the area.Ore bodies are stratoid and lenticular.④Wamiaopo copper deposit is a volcanic and subvolcanic sedimentary-retransformation type copper deposit.The mineralization is mainly veinlet-disseminated,net⁃work veinlet,scattered disseminated and massive ore.Comprehensive analysis shows that the mineralization of Wamiaopo copper deposit is closely related to strata,structure and magmatic rocks.It is a volcanic,subvo⁃lcanic sedimentary-retransformation copper deposit formed by multiple factors.
