西藏扎格拉金矿位于班公湖-怒江结合带(简称丁青结合带)南侧的班戈—腾冲岩浆弧带，矿体严格受侏罗统希湖群浅变质复理石岩系中断裂破碎带控制，金矿化围岩蚀变包括有硅化、绢云母化、黄铁矿化(褐铁矿化)、碳酸盐化、粘土化、绿泥石化等。地球化学有 Au、As、Sb、W、Mo、Cu 元素组合的异常，对金矿勘探具有很好的指示作用。全面详细总结了扎格拉金矿成矿地质特征，结合野外地质调查认为扎格拉金矿成因属于变质-热液型金矿床类，工业类型为少硫化物金矿石，同时提出本地区该类型金矿的找矿方向。

Zhagela gold deposit of Tibet was located in Bange-Tengchong magmatic arcbelt on the southern limb of Bangonghu-Nujiang conjunctive belt (or Dingqing conjunctive belt).The ore-bodies were strictly controlled by faulted fracture zone in epimetamorphic flysch rock series of Jurassic Xihu Group.The gold mineralization wall rock alteration included silicification,sericitization,pyritization (ferritization),carbon-atization,argillization and chloritization.In respect of geochemistry,anomalies of element associations of Au,As,Sb,W,Mo and Cu occurred and they were effective clues for gold prospecting.This paper compre-hensively summarized the metallogenic and geological characteristics of Zhagela gold deposit,and based on field survey it believed that Zhagela gold deposit was a metamorphic-hydrothermal gold deposit in term of genesis,and was low-sulfide gold ores in term of industry type.The paper also proposed the prospecting di-rection of such type of gold ores in this area.
