摘要
铜锡山金矿产于牟乳断裂带的南部,为一含金石英脉型金矿。矿床的地质特征和矿床地球化学资料的对比分析表明,成矿受NNE向断裂控制,与金矿体同时空产出的煌斑岩对成矿亦有重要的控制作用;成矿物质为壳源和幔源的混合来源,成矿流体主要以岩浆水为主,有部分大气降水加入;矿床属于与燕山晚期构造-岩浆作用有关的中低温热液矿床。
Tongxishan gold deposit is located in the south of Muping-Rushan fault belt belonging to quartz vein-type gold deposit.Ore-body is mainly controlled by NE,NNE faults and by lamprophyric dykes which occur the same as the gold ore bodies temporally and spatially.Preliminary studies of geochemistry and stable isotopes reveal that the ore-forming materials are mainly derived from mixture of magmatic and crust source,and the mineralizing fluid is mainly magmatic water incorporated with some meteoric water.This suggests that the Tongxishan gold is a medium-low temperature hydrothermal Au deposit related genetically to Late Yanshanian tectonics-magmatism.
