Characteristics of ore-forming structural plane and their ore-controlling effect on Carlin-type gold deposits in Laizishan anticline area,southwestern Guizhou
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 de-posits 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 ar-ea is mainly controlled by the secondary ore structural plane.
