摘　　要：西藏努日矿区属冈底斯成矿带东段克鲁-冲木达矽卡岩亚带,通过多年地质普查工作,初步形成大型层矽卡岩型铜钨钼多金属矿床。本文通过对层矽卡岩型铜钨钼矿体地质特征、矿石质量、矿石类型、矿床成因及找矿标志等研究和分析,显示出热水环流和深部侵入岩浆热液的叠加和富集成矿作用特点,为矿区深部寻找斑岩型铜多金属矿提供依据和预测。Nuri ore district in Tibet is located on Kelu-Chong Muda skarn sub-belt which lies at eastern Gangdise metallogenic belt of Tibet.Through years of geological survey,a large-size layer skarn copper tungsten and molybdenum multiple-metal deposit has been discovered.By studying and analyzing geological characteristics,ore quality,ore type,ore genesis and prospecting signs of the layer skarn Cu-W-Mo orebody,this paper is going to summarize the characteristics of superposition and enrichment mineralization between hydrothermal circulation and intrusive magma hydrothermalism,which holds the idea of providing evidences and prediction for prospecting porphyry Cu polymetallic ore in deep areas of diggings.
