Structural Systems of Fankou Lead-Zinc Orefield in Renhua County, Guangdong Province, China

Orefield structures of Fankou lead-zinc deposit in Guangdong province is complex and have been argued about for years. On the basis of the theory and method of the geomechanics, the mechanics features of structural planes of the structures of Fankou lead-zinc orefield have been identified. Its indicated that its structure is divided into three types of systems, that is, the northwest trending structural belt which origin from the Caledonian stage to the Hercynian stage, the Lambda-type structure which origin from the Indo-Chinese stage to the Yanshan stage and the eastweat trending structural belt which origin the Himalayan stage. The lambda-type structure made of major fault of F203 of strike northwest and branch fault of F3, F4 of strike northnortheast is identified as the structural system of mineralization.
