摘要
层控块状硫化物型铜矿床,是九江—瑞昌地区铜矿床中重要的组成部份,它常在一个矿区与矽卡岩铜矿床、斑岩铜矿床的贴邻地段产出,组成所谓“三位一体”。层控块状硫化物型铜矿床,具有独特的地质特征,矿体受层位、岩性控制,走向稳定,形态简单,以含钢黄铁矿石为主,具有同生沉积结构构造。本文运用被人们所忽视的传统地质理论揭示矿床受后期地质构造、岩浆热液改造、迭加的主要特征,从面阐明矿床为沉积—改造(再造)—迭加复合作用形成,即以沉积改造为主,迭加为次的成矿物质多来源,成矿多期次,多成因的复合型铜矿床。
The stratabound massive sulfide copper deposits form an important part of Jiu-Rui copper orefleld, which are usually associated with skarn-type and porphyry-type copper deposits, forming so called 'Trinity depostis '. The stratabound massive sulfield copper orebodies are characterized by stratigraphical and lithological control, stable strike, simple shape and dominant of Cu-bearing pyrite, with contemporaneous sedimentary texture and structure. In this paper, we reveal the main characteristics of reformation and superimposition of ore deposits resulted from post-geologic-tectonic and magmatic hydrothermal activities, to expound their sedimentation-reformation-superimposition origin. We consider that they delong to polygenetic copper deposites experienced sedimentation reformation and superimposition.
