摘　　要： 梧桐沟铜矿床是新疆东南天山发现的一种新类型铜矿,矿床产于下泥盆统阿尔彼什麦布拉克组上亚组中—酸性火山岩和火山碎屑岩地层中,容矿岩石为熔结凝灰岩、凝灰质砾岩和酸性斑岩,成矿作用与构造、脉岩及蚀变密切相关。通过矿区成矿地质特征、矿石矿物特征、地球化学特征的分析研究,将其划归为陆相火山热液脉型铜矿床,并对该矿床找矿标志进行了探讨。 As a new type of copper deposit, Wutonggou copper deposit was found in southeast Tiaushan, Xinjiang, it formed in the intermediate-acidic volcanic rocks and pyroclastic rocks strata of upper Albishimai Bulakon formation in the lower Devonian;the ore-hosting rock are self-fused tuff, tuffaceous conglomerate and acid porphyry;and the mineralization is closely related to structure, dikes and alteration. Through the analysis on the ore-forming geological features, the characteristics of ore and minerals, as well as the geochemical characteristics, the author concludes it as a terrestrial volcanic hydrothermal vein type copper deposit, moreover, the prospecting criteria of this kind deposit is discussed in the paper.
