| 摘 要： | 本文扼要地阐述了地幔柱构造的研究历史和现状，指出地幔柱构造作用是地质构造作用、火山岩浆活动、沉积变质作用、成矿作用体系的原动力；论述了华南中、新生代地幔柱构造的存在、作用特点及其与华南铀矿化的关系。华南４大类型的铀矿化应是在统一的地幔柱构造作用和影响下的产物。地幔柱构造不仅为铀的活化、迁移和富集提供热动力，而且还可能提供成矿物质来源，对进一步深入认识我国华南铀矿区域成矿规律，扩大老矿区，探索寻找成矿新区和新类型铀矿化具有积极的意义。

| Abstract: | This paper briefly introduces the research history and trends on mantle plume tectonics, which is considered to be primary origins of geotectonics-volcanism/magmatism-sedimentation-metamorphism and metallogenesis system. The activities of the Meso Cenozoic mantle plume tectonics, its features and relationship to uranium mineralization in South China are discussed. The classified four main types of uranium deposits in South China must be formed under direct or indirect influence of the mantle plume tectonics, which provides not only dynamic energy for processes of uranium migration, mobilization and enrichment, but also ore sources for mineralization. Those considerations are of important significance to more deeply understanding uranium regional metallogenetic regularity, enlarging resources of the known ore fields and searching for new uranium mineralized areas and mineralization types as well. |
