摘　　要：松树南沟金矿位于红沟-庄浪加里东期陆缘裂谷带的中西段,南与中祁连前武纪隆起带前加里东期大坂-兴隆山陆块毗邻。区域构造背景反映了一个在前寒武纪基底上于晚奥陶世拉张的被动陆缘裂谷环。通过对矿区地质构造特征的系统研究,确定了松树南沟金矿床位于古亚洲构造域中朝板块北祁连板段北祁连山环太平洋型俯冲带(缝合带),并靠近大坂山深大断裂带。构造(接触带构造、片理化带和断裂构造)为矿液运移提供通道和储矿空间。Songshunangou gold deposit is located in the Honggou-Zhuanglang caledonian period in west-middle section of the epi-continental rift zone, in the north of the Qilian pre-caledonian period and pre-cambrian uplift-Xinglong mountain block adjacent. Through the systematic study on the geological structure, we determined the location of the gold ore deposit. The structure provided the channel for fluid migration and storage space.
