| 摘 要： | 文章应用地幔柱构造理论,对华南多金属成矿省铀、钨等矿种的成矿作用与地幔柱构造的内在联系进行了分析与探讨,提出华南的核心地段存在以桂东幔凹大型构造网结-浆源活动中心的同位套环（内环Ⅰ、中环Ⅱ、外环Ⅲ）的亚地幔柱构造。初步厘定准幔柱（热点）构造20余处,总体上它们控制了华南核心地带的钨、铀等金属矿种的空间展布。指出应以华南亚幔柱内环为重点,兼顾中环和外环准幔枝（热点）构造成矿有利地段进行深部探索的择靶方向。

| Abstract: | The relationship between metallogenesis of uranium, tungsten, etc. and the structure of mantle plume in South China multi-metal metallogenic province is discussed and analyzed with the mantle plume theory. A sub-mantle plume of embedded rings (inner ringⅠ, middle ringⅡand outer ringⅢ) representing the centre of a large mantle concave-magmatic activiation was proposed in the kenel of East Guangxi area in South China. Over 20 hotspots were primarily recognized, and their control to the central metallogenic area for uranium, tungsten,etc. was also summarized. The metallogenic prospecting should focus on the inner ring area and attention should be payed to the middle and outer ring area. |
