| 摘 要： | 朗达铜矿处于雅鲁藏布江弧-陆碰撞结合带的北侧，冈底斯陆缘火山-岩浆弧南缘，属于贡嘎-加查东西向铜多金属成矿带，产于喜马拉雅期中酸性岩浆岩的断裂带中.目前发现的2条矿（化）带呈脉状、透镜状、似层状产出，且受矿区近东西向或北西西向的断裂控制.矿石构造主要以条带状、脉状及角砾状为主，部分聚合体为斑杂状或浸染状.通过对矿区地质、矿体及矿石特征仔细分析后，认为该矿床主要受构造、岩浆热液控制，具备良好的找矿前景.

| Abstract: | The Langda copper deposit,located in the southern margin of the Gandise volcanic-magmatic arc on the north side of the Yarlung Zangbo arc-continent collision zone,belongs to the east-west-trending Gonggar-Jiacha copper-polymetal metallogenic belt.The deposit occurs in the fault belt in Himalayan acidic-intermediate magmatic rocks.Two mineralized belts were found in vein,lenticular and layered shapes,controlled by E-W-and NWW-trending faults.The ores are dominated by banded,veined and brecciform textures,with part of taxitic or disseminated ones.Analysis on the geology of orefield and the features of orebodies and ores reveals that the deposit is mainly controlled by structure and magmatic fluid,with good ore-searching prospect. |
