摘　　要：赖子山背斜位于黔西南卡林型金矿矿集区中部,成矿条件优越。通过对赖子山背斜区内成矿结构面特征的归纳总结,对区内卡林型金矿的控矿作用进行剖析。结果表明:研究区主要发育原生成矿结构面和次生成矿结构面,成矿结构面对金矿的控制作用表现在对金矿体产出、规模、形态、厚度和品位的控制,并指出赖子山背斜区卡林型金矿成矿主要受次生成矿结构面控制。The Laizishan anticline is located in the central part of the Carlin-type gold deposit concentration area in southwestern Guizhou,with superior metallogenic conditions.By summarizing the characteristics of metallogenic structural planes in the Laizishan anticline area,the ore-controlling effect of Carlin-type gold deposits in the area is analyzed.The results show that the primary ore structural plane and the secondary ore structural plane are mainly developed in the study area.The control effect of the ore-forming structural plane on the gold deposit is manifested in the control of the output,scale,shape,thickness and grade of the gold ore body.It is pointed out that the mineralization of the Carlin-type gold deposit in the Laizishan anticline area is mainly controlled by the secondary ore structural plane.
