Genetic Types of Granite Controlled the Mineralization in Qimantage Area, Eastern Kunlun

Qimantage area discovering abundant mineral resources lies in the western sector of eastern Kunlun orogenic belt,and neutral-acid granite magmatic intrusion happened frequently,moreover fault structures were well-developed.Most of the deposits in study area are controlled directly or indirectly by granite magmatism in each period.According to the research on granite genetic types,the author has briefly introduced the genetic types of granite rocks controlled the mineralization,for example,several important deposits are respectively related to the Caledonian stage or the late Indo-Chinese stage.The results showed that the granite bodies of the different granite genetic types in the same period were formed into the different deposit,whereas the granite bodies of the same granite genetic types in the different period were formed the similar deposit.In the Caledonian stage,the A or (A+S)-type granitoid formed the Baiganhu-Jialesai large-scale W-Sn deposit,however,the I-type granit oid formed the Ulan Uzhur Cu-Sn deposit.In the Caledonian stage and late Indo-Chinese stage,although metallogenic epoch of two deposits are different,yet the I-type granitoid formed both the Ulan Uzhur Cu-Sn deposit and Kaerqueka Cu-Mo deposit.
