| 摘 要： | 笔者在本文中总结了北岔沟门银多金属矿田的断裂构造特征.矿田内的断裂构造可分为成矿前断裂、成矿期断裂及成矿后断裂,特殊的大地构造位置铸就了复杂的构造环境,不同期次的断裂对矿体的形成、改造起到了不同的作用.矿体主要赋存于D7-D5-D8及D2-D4-D8两个断裂构造活跃带内.成矿期断裂构造具有多个方向、多期多阶段、等距性等特点,形成了矿田内由高温到低温的不同矿种的矿床组合,组成了矿田内的矿化网络,具有低阻高极化特征.

| Abstract: | The fault characteristics of in the Beichagoumen Ag-polymetallic ore field are summarized in this paper.The Fault evolution can be divided into three stages,including pre-mineralization period,mineralization period and post-mineralization period in this ore field,which have played different roles in the formation of ore bodies and modification.The special geotectonical location exhibits a complicated tectonic environment.The ore bodies mainly exist in two active faults.One fault is in the D7-D5-D8 zone,the ... |
