| 摘 要： | 金家洞萤石矿位于彭山背斜构造北西翼,萤石矿体赋存于中奥陶统汤山组的硅化破碎带内。受区域北东-南西向断裂构造控制,矿体具中等规模,埋藏浅、质量好。矿石类型以纯萤石型、石英-萤石型、硅化灰岩-萤石型为主,次为方解石-萤石型、方解石-石英-萤石型。矿床成因属岩浆期后低温热液充填交代型矿床,成矿作用与燕山期岩浆活动密切相关。

| Abstract: | The Jinjiadong fluorite deposit is located on the northwest limb of the Pengshan anticlinalstructure, with the orebodies occurring in the silicified fractured zone in the Ordovician strata of Tangshan Formation Controlled by NE- sinking fault structure , the orebodies are of medium size, shallow burial depth and good quality. The ores are dominated by fluonte type, quartz- fluorite type, silicified limestone - fluorite type, with subordinate calcite fluorite type, calcite - quartz - fluorite type Genetically the deposit is of a postmagmatic low - temperature hydrothermal cavity filling and metasomatic type, while mineralization is intimately related with the Yanshanian magmatism |
