摘要
广东省揭西县金坑铜锡铅锌多金属矿床位于惠阳—梅县新华夏构造带之莲花山深断裂带内。通过野外地质调查及室内综合研究,认为该矿床为构造动力变质热液型铜锡铅锌矿床,具有矿化范围广、规模大、矿脉发育、金属矿物品位变化大、成矿多期多阶段性的特征;地层岩性、构造、岩浆岩是该矿床的主要控矿因素,NE—NNE向新华夏裂隙带、片理化带及其配套断裂是该矿床的主要容矿构造,动力变质带是该矿床的重要控矿因素。莲花山深断裂带具有"金坑式"矿床的找矿潜力。
Jinkeng Cu-Sn-Pb-Zn polymetallic deposit in Jiexi C o un ty, Guangdong Province is tectonically located in the Lianhuashan deep fault zone in the Huiyang-Meixian Neocathaysian tectonic belt. In order to explore the genesis of ore deposit and ore controlling fa c to rs , this study carried logical survey and comprehensive analysis of geological data. The results show th at the metamorphic hydrothermal type of Cu-Sn-Pb-Zn deposit driven by tectonic a ctivity, characterized by ex-tensive mineralization,large scale, well developed ore-bearing veins, varied g rad e s, multiple stages. Li-thology, structure and magmatic rocks are the main ore controlling factors. NE-to NNE-trcathaysian fractured zone and schistositilized zone and its accompanying faults are the major ore-bearing structures. Dynamic metamorphic bett is an important ore controlling factor for the Jinkeng Cu-deposit. T h e re fo re ,the Lianhuashan deep fautt is of exploration potential for the Jinkeng-type deposits.
