库布苏金矿床位于新疆准噶尔褶皱系东准噶尔褶皱带中部，野马泉地块南缘晚古生代火山岩浆弧带，产于一大型韧-脆性剪切变形带---库布苏强应变构造带中。区内构造极为发育，以N WW向断裂为主，并已发生强烈挤压片理化和糜棱岩化；区内出露含金背景值较高的志留系库布苏群海相火山碎屑岩系；岩浆活动频繁，主要为超浅成侵入的脉岩，岩性为闪长玢岩、石英闪长斑岩和霏细斑岩等。金矿床受岩脉内韧-脆性剪切形成的构造扩容、糜棱岩化带控制，构成赋矿围岩。矿床类型为破碎蚀变岩型，矿体的形成经历了2个期次脉岩（闪长玢岩、石英闪长斑岩）侵入造成的成矿元素迁移富集阶段，矿化富集程度与脉岩内构造扩容、变形及蚀变糜棱岩化程度密切相关。通过对其地质背景与成矿特征的论述，分析了矿床的成矿规律、成矿期次及区内大量脉岩与金成矿的物质成分与空间联系，初步建立了矿床综合找矿模式，以期对深部找矿提供裨益。

Kubusu gold deposit is located in the East Junggar fold belt of Junggar fold systems,and the Late Paleozoic volcano magma ore belt in the southern margin of the Yemaquan crustal block it lies to the Kubusu strong strained tectonic zone which is a large ductile-brittle shear deformation belt.There are strong tectonic activity in the area especially development NWW strike regional fracture,and have strong deformation of squeezing,schistosity and mylonitization.The stratum are mainly the marine volcanic clastic rocks which have higher gold abundance in Kubusu Group of Silurian system.There are frequent magmatic activity in this area that the lithology is mainly super-hypabyssal intrusive rocks of diorite porphyrite,quartz diorite porphyry,felsophyre, etc.The gold deposits are controlled by the tectonic expansion and mylonitize belt,whose formation by process of ductile-brittle shear in the vein rocks,and that constitute the ore rocks.The gold deposit is the crushing alteration type,and the orebody formation has experienced two stages of ore-forming elements enrichment which caused by the intrusion of vein rocks(diotite porphyrite, quartz diorite porphyry) in the two period of time. The mineralization enrichment degree is closely related to the tectonic expansion,development of the deformation and mylonitization.We analyzed the metallogenic law and phase,and the relationship between material composition and interspace massive vein rocks and gold ore-forming by discussing the geological background and metallogenic characteristics.The comprehensive prospecting model of the deposit was built in order to provide helpful for deep prospecting.
