西藏多不杂斑岩型铜金矿床位于西藏-三江造山系中的羌塘弧盆系与班公湖-怒江-昌宁-孟连结合带西段结合处的中生代多不杂构造岩浆弧中。出露地层有中生界三叠系日干配错组;侏罗系曲色组、色哇组;白垩系美日切错组;古近系渐新统及第四系。矿集区断裂构造较为发育,具有时间长,多次活动的特点。矿区内见岩浆岩发育,主要有花岗闪长斑岩、花岗斑岩、花岗闪长岩、闪长岩、二长花岗斑岩、辉绿岩,岩体分布受近东西向断裂控制,总体具有呈近东西向分布的特点。岩体侵入时代均
The multi-porphyry copper-gold deposits in Tibet are located in the Mesozoic multi-non-structural magmatic arc at the junction of the Qiangtang argillaceous system in the Tibet-Sanjiang orogenic belt and the western part of the Bangong Lake-Nujiang-Changning-Menglian conjunction belt . Exposed strata are Mesozoic Triassic Rganzuo misfit group; Jurassic song group, color wow group; Cretaceous America-Japan group; Paleogene Oligocene and Quaternary. The ore-bearing area fault structure is more developed, with a long time, multiple activities. Magmatic rocks are found in the mining area, mainly including granodiorite porphyry, granite porphyry, granodiorite, diorite, monzonitic granite porphyry and diabase. The distribution of rock mass is affected by the recent east-west fault Control, with the overall distribution of the characteristics of the nearly east-west. Rock invasion time are
