摘要
现代金成矿地球动力学的研究，揭示了矿床及其组合与构造变动、岩浆活动一样，是地壳变革的一个事件，因此从成矿环境地质方面可反演矿床及其组合的形成史，正确划分出与区域地壳演化阶段相适应的矿化类型；滇黔桂卡林型金矿的形成与右江幔隆的发生、发展息息相关，本文借用金成矿地球动力学的一些思想，用地幔隆起的观点分析了本区卡林型金矿的形成。
Modern geodynamic studies of gold metallogenesis has revealed that the ore deposits and their assemblages, like tectonic changes and magmatic activities, are a kind of geological events during the evolution of the Earth. Therefore,the geological environment of metallogenesis can reflect the history of formation of ore deposits and their assemblages. On this basis, the mineralization types corresponding to the evolution stages of a regional crust can be correctly distinguished.The Carlin-type gold deposits in the Yunnan-Guizhou-Guangxi area are closely genetically connected with the generation and development of the Youjiang mantle uplift. This paper analyses the mechanism of formation of the Carlin-type gold deposits in this area in terms of the modern geodynamic data on gold metallogenesis and from the view of point of mantle uplift.
