ABSTRACT
Basic rocks are closely related to gold mineralization. This article starts with the geological characteristics of the Zhesang gold deposit, and describes in detail the geological characteristics of the deposit, the alteration and mineralization of the surrounding rocks of the ore body, etc., and based on the age determination of the Zhesang gold deposit and the tectonic evolution history in South China. The relationship between basic rocks and gold deposits is explained in terms of chronology and regional tectonics, and on this basis, a dynamic model of Indosinian metallogenesis is proposed, that is: the closure of the Paleo-Tethys Ocean led to the Indosinian plate and the Yangtze Plate collisions and strong regional tectonic events provided a driving force for mineralization, forming the Carlin-type gold deposits in the Yunnan, Guizhou, and Guizhou regions.
