摘要(Abstract)：

三江成矿带北段治多-玉树地区已显示出较大的铜多金属矿成矿潜力。在已有研究成果的基础上,结合详细的野外调查和室内研究,对三江北段治多-玉树地区新发现的典型铜多金属矿床的地质特征、成因类型和成矿构造环境进行了综述。这些矿床普遍赋存于中酸性火山岩中,空间上具"火山碎屑岩-矿体-热水沉积岩"的分布特征。矿体多为层状、似层状,且矿石品位较高。对比研究表明,治多-玉树地区铜多金属矿床地质特征与四川呷村矿床和日本"黑矿"矿床相似,成矿流体可能系岩浆水和海水的混合流体;成矿物质可能源于岛弧岩浆作用,并含有热液交代围岩所萃取的金属元素。研究结果表明该区以火山岩为赋矿围岩的铜多金属矿床应归属为VHMS型,成矿构造环境可能与晚三叠世甘孜-理塘洋向南俯冲的大洋岛弧-大陆边缘岛弧环境有关。
