摘　　要：该区金矿成矿作用受右江盆地的演化密切控制，北西向的区域断裂是主要的控矿、导矿构造；盆地内穹窿构造的周边是金矿床分布集中区，周边环形（复活）断裂兼具容矿构造特征；低序次断裂构造使矿体就位。隆林新洲背斜及富宁等地为新的成矿远景区。On the basis of field study and synthetic analysis of regional geology and the characteristics of gold deposits, the author places an emphasis on the analysis of ore-controlling structure in the contiguous zone of Yunnan-Guizhou-Guangxi and comes to several new understandings as follows: (1)The gold mineralization related closely to the evolution of Right of Right-River basin; (2) NW-striking regional faults are major important ore-controlling structure (structure as passage-way for ore fluid); (3)The edge of dome within the basin is the centralized zone of gold mineralization, and the sided arrounding reactivity faults also have the characteristics of passage-way for ore fluid and ore-hosting structure; (4)The low classic fault structure locating ore bodies At last, this paper suggests regional ore-finding forecast on the basis of summarization of ore-controlling structure
