摘要
基性岩与金矿成矿关系密切。本文从者桑金矿的地质特征入手,详细描述了矿床地质特征、矿体围岩蚀变及矿化特征等,并依据前人对者桑金矿的年龄测定及华南区域构造演化史,在年代学及区域构造方面阐述基性岩与金矿的关系,并在此基础上提出一种印支期成矿的动力学模型,即:古特提斯洋的封闭导致了印支板块与扬子板块的碰撞,强大的区域构造事件为矿化提供了驱动力,形成了滇黔桂地区的卡林型金矿床。
Basic rocks are closely related to gold mineralization. This article starts with the geological cha-racteristics 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.
