摘　　要：塔拉斯-卡拉塔乌地块主要由马拉卡罗伊地体、郭克焦特地体、乌祖纳哈玛特地体三个构造单元组成。南以塔拉斯-费尔干纳右行走滑断裂、尼古拉耶夫线为界,与中天山相邻;北以苏扎克-伊其格列塔乌-阿拉木苏伊断裂为界,与北天山相隔。3个构造单元沉积建造在不同地质时期各不相同,根据含矿建造及矿床、矿点分布特征可划分为4个多金属成矿带。长期的构造演化和岩浆活动使该区域的成矿作用叠加在一起,但总体上以加里东晚期碰撞挤压岩浆作用成矿为主。Talas-Kalatawu block is composed of Malakaluoyi terrane, Guokejiaote terrane and Wuzunahama＇te terrane. The southern boundary of Talas-Kalatawu block is Taras-Fergana dextral strike-slip fault, and adjacent to Mid-Tianshan; the northern boundary is SuzaqYiqigelietawu-Alamu Zoe fault, and adjacent to North Tianshan. The three tectonic units varies from one another due to their sedimentary formation in different geological periods. According to the mineral-bearing formation and distribution of ore deposits and spots, the Block can be divided to four polymetallic mineralization belts. Long-term tectonic evolution and magmatic activity lead to the mineralization stacking in this field, however, the metallization is mainly formed by collision and extrusion magmatism in the late period of Caledonian orogeny.
