| 摘 要： | 文章阐述了地幔柱和热点活动的基本概念，并划分热点活动为大陆型和大洋型；扼要阐述了热点活动与成矿作用的关系，提出了热点铀成矿作用理论。华南中新生代（220～50Ma）的地质构造作用、岩浆活动、沉积和变质作用、成矿作用与深部地幔柱构造作用有着密切关系。从地质、地球物理和地球化学等方面论证了贵东东部为中生代大陆型热点活动地区及其与铀成矿作用的关系，指出了华南热液型铀矿找矿远景。

| Abstract: | The basic concepts of mantle plume and hotspots are expounded and the hotspots are classified into continental and oceanic types. The relationship between hotspots and metallogenesis are briefly discussed, and a new theory of uranium metallogenesis related to hotspots has been put forward. The geotectonism, magmatism, sedimentation, metamorphism and metallogenesis must be closely associated with deep geodynamics of mantle plume tectonics in Meso-Cenozoic period from 220 Ma to 50 Ma in South China. The eastern part of Guidong granite massif has been proved to be a Mesozoic hotspot from aspects of geological, geophysical and geochemical evidences and its correspondent relationship to uranium metallogenesis is discussed. Finally, the uranium metallogenetic perspect has been pointed out for hydrothermal uranium mineralization in South China from the view point of hotspot uranium metallogenesis. |
