通过对阿西金矿床地质特征、成矿条件和矿床成因的研究,认为阿西金矿床产于中三叠统扎尕山组第三、四段的碎屑岩和碳酸盐岩中,赋存于闪长岩体的内、外接触带,受NW向断裂带控制。金矿(化)带的形成与闪长岩体有密切关系,产于岩体外接触带围岩构造破碎带中的金矿体是阿西金矿床最重要的矿体。矿体形态为脉状、似层状及透镜状,矿体厚度及品位变化不大,矿化相对均匀。金矿化与硅化、碳酸盐化、黄铜矿化、黄铁矿化关系密切。中酸性岩浆活动与断裂构造是矿床形成的先决条件。该矿床成因为岩浆及(期后)热液改造型矿床。
Based on the study of the geological characteristics, metallogenic conditions and genesis of the Asi gold deposit, it is considered that the Asi gold deposit is produced in the third and fourth clastic rocks and carbonate rocks of the Zhagashan Formation in the Middle Triassic, The inner and outer contact zones of diorite bodies are controlled by the NW fault zone. The formation of gold (chemical) belt is closely related to the diorite body. The gold orebody that is produced in the crustal belt of the surrounding rock of the outer contact of the rock mass is the most important ore body of the Asi gold deposit. The ore body morphology is veins, like stratified and lenticular, ore body thickness and grade change little mineralization is relatively uniform. Gold mineralization and silicification, carbonation, chalcopyrite, pyrite mineralization are closely related. Meso-acid magmatism and fault structure are the prerequisites for the formation of the deposit. The deposit is due to magmatic and (later) hydrothermal mineralization.
