摘要
建阳大金山铅锌矿床产于下元古界麻源群南山组中 ,麻源群提供了部分成矿物质。前加里东期区域变质使铅锌等成矿元素活化、迁移 ;燕山期构造岩浆活动使铅锌等沿北东、北东东向断裂、裂隙富集成矿。矿床为中低温浅成岩浆热液交代 -充填成因。
The Dajinshan Lead-zinc Deposit in Jianyang County, Fujian Province is distributed over the Lower Proterozoic strata of Mayuanqun Group Nanshan Formation, which is the supplier of some minerogenetic materials. The pre-Caledonian regional metamorphism makes such minerogenetic elements as lead and zinc activation and migration, and the Yanshanian tectonic magmatism causes the enrichment and ore-formation of lead and zinc along the NE and NEE-trend faults and fissures. The Deposit belongs to the one of the type of the mesothermal and microthermal hypabyssal magmatic and hydrothermal filling and replacement.
