摘　　要：新疆西天山下石炭统大哈拉军山组地层中产有众多的金矿体。通过对昭苏水磨沟铜金矿床矿化特征的研究 ,总结出这类矿床的成矿规律是 :下石炭统大哈拉军山组中酸性火山岩是矿源层 ;区域性大断裂是矿质运移通道 ,其中的低级别、低序次构造为容矿空间 ;华力西期钾长花岗岩是形成铜金矿的能量来源 ;绿片岩相以下的动力变质作用是矿化富集的条件。There are many gold deposits occurring in the Dahalajunshan Group of Carboniferous in western Tianshan, Xinjiang, China. Based on the investigations of geological characteristics of the gold and copper deposit in Shuimogou, the metallogenic law of such a deposit can be summarized as follows. Intermediate acid lava in the Dahalajunshan Formation of Carboniferous is the resource bed; Regional faults are the routes of carrying metallogenic elements, in which the little faults are the interspace of containing minerals ; Granite is the energy resource; Dynamical metamorphism under greenschist facies is the condition of mineralizing enrichment. The genesis of the gold deposits of the fragmented altered rock type.
