工作区位于礼县-岷县成矿带西段，区内地层系统发育较为齐全，地层岩性组合多为砂岩和板岩互层，有利于金成矿的运移和保存，叠加褶皱和断裂控制着矿体空间定位及矿床分布。花岗岩体的活动与金成矿关系密切，脉岩与矿脉空间关系密切。金矿成矿与热液活动有关，各类热液蚀变极为发育，与金成矿密切相关的热液蚀变主要为碱质交代作用、硅化、黄铁矿化、碳酸盐化和褐铁矿化等。通过对区内地层、构造、岩浆岩及变质情况进行分析，结合区内已发现矿床的研究成果、区内化探及遥感成果，综合各种有利找矿信息，预测出塔儿里别竜沟和北门沟3个成矿靶区。

The work area is located in the Li (county)-Min (county)metalloge nic belt where the layer system developed completely,the Lithology combination mostly interblended sandstone and slate which in favor of the migration and preservation of gold mineralization,additionally,folds and faults controlled the spatial orientation and distribution of ore deposits.There is a close relationship between activities granite and Au metallogenic,as well as dikes and veins in the areas.At the same time,the gold mineralization and hydrothermal activities also have a close relationship.The various types of hydrothermal alteration is very well developed,and the hydrothermal alteration which closely related to the Au variable is mainly alkali metasomatism,pyritization,silicification,carbonation, limonitization etc.Anglicizing the stratum,structure,magmatic and metamorphic conditions and combined with the research results of the mineral deposit,the geochemical and the remote sensing in the region,3 mineralization targets(Taerli,Biekungou,and Beimengou)were predicted.
