江西省东乡虎形山金铅锌矿构造控矿规律分析

Discussion on ore-controlling regularity of structure of Huxingshan Au-Pb-Zn deposit in Jiangxi Province

断裂和火山机构是虎形山金铅锌矿的主要控矿成矿因素。赛阳关火山活动晚期第二次侵入活动为该区金铅锌成矿提供了矿源及热液流体。矿床定位于东乡—广丰深断裂带次级NNE向、NE向及NW向张性、张扭性断裂和破碎蚀变带内(控矿构造),再次级近SN向断裂,为本区成矿构造(容矿构造)。该认识更全面把握构造对虎形山金铅锌矿成矿控制作用,可为下一步找矿提供参考。

Geological and volcanic structures are the main ore-controlling factors of Huxingshan Au-Pb-Zn deposit.The second intrusive activity in the late stage of Saiyangguan volcanic activity provided ore source and hydrothermal fluid for gold-lead-zinc mineralization in this area.The deposit is located in the secondary tensional and tensional-shear fault and fractured alteration zones in NNE,NE and NW direction of Dongxiang-Guangfeng deep fault zone.The sub-secondary SN fault is the ore-forming structure（ore-bearing structure）in this area.This understanding comprehensively grasps the ore-controlling function of structure in Huxingshan Au-Pb-Zn deposit.It could provide the reference for the next-step prospecting.
