摘要
The metallotectonical types in Dayaoshan can be divided into two types: fluid-type metallotectonics and tecto-type metallotectonics. The fluid-type metallotectonics include fluid-vein type, fluid-breccia type and fine fluid-vein type. The tecto-type metallotectonics include structural altered rock type and structural vein type. The structural analysis shows the ore-controlling structures in Taohua gold deposit to be an extensional brittle-ductile shear zone, mainly including eanly fluid-vein type metallotectonics, and structural altered rock type metallotectonics. Based on the divisions to the metallotectonical types and studies to ore-controlling structure types, this paper makes an assessment of the mineralization prospect of major gold deposits in Dayaoshan area in Guangxi.
