摘　　要：拉荣斑岩型钨(钼)矿床在大地构造位置上位于羌塘弧盆系唐古拉-左贡地块上,区域成矿带为类乌齐-左贡Sn-Pb-Zn(Ag)成矿亚带。矿区赋矿地层为下石炭统卡贡群下岩组(C_1Kg^1),岩性为灰色板岩、变质砂岩偶夹结晶灰岩、大理岩。矿区内中酸性浅成侵入岩体为主要的含矿流体及热源。主含矿斑岩体受有NW向和近SN向两组断裂控制。在近SN向的层间构造破碎带中见矽卡岩型钨矿。通过对矿床地质特征和成矿时代的研究,及对拉荣斑岩型钨(钼)矿床成因的分析,初步认为该矿床为与浅成侵入岩有关的高温热液型矿床。Pull Rong porphyry tungsten （ molybdenum）deposit located in the tectonic position Qiangtang arc basin systemTanggula - on Zuogong Lot, regional metallogenic belt as Riwoqe - Zogang Sn - Pb - Zn （ Ag） mineralization subzone.Mining ore Lower Carboniferous strata Kagong rock group undergroup （C1Kg1） , lithology is gray slate, metamorphic sandstonefolder even crystalline limestone, marble. Acidic mining areashallow intrusive rock as the main ore - bearing fluids and heat.The main ore - bearing porphyry that have NW and nearly SN -trending faults control. See skarn tungsten mine near SN betweenthe layer structure of the broken belt. By studying the geologicalcharacteristics of the deposit and mineralization age,and analysis of the causes of the pull - wing porphyry tungsten（molybdenum） deposits, the deposit is considered preliminaryand shallow intrusive rocks related to high - temperature hydrothermaldeposits.
