摘　　要：西藏冈底斯带尼木西北部具有斑岩型铜矿产出的有利地质条件 ,已有厅宫、冲江、白容、岗讲、渡布曲等铜矿床 (点 ) ,可望形成大型—超大型斑岩铜矿集中区 ,其资源量远景可达 40 0～ 6 0 0万t以上。在分析地质背景的基础上 ,总结了矿床的地质特征 ,并与国内外斑岩铜矿进行了对比 ,建立了本区铜矿的综合遥感地质找矿模型。There is a favorable geological condition for the formation of porphyry-type Cu deposit in the northwestern Nimu County, middle section of Gangdisi belt, Tibet. In the area, there are many Cu deposits and spots such as Tinggong, Chongjiang, Bairong, Ronggangmeng, Gangjiang, and Dubuqu, which can be formed as large or superlarge porphyry-type Cu concentrated area whose potential resources may be ranged from 4 Mt to 6Mt. On the basis of geological setting, mineralizing characters are summarized, and compared with those of other porphyry-type Cu deposits in China and abroad. Finally the comprehensive remote-sensing prospecting model for copper deposits is proposed.
