%X 诸广山复式岩体地处湘赣粤三省交界，为我国重要的铀多金属成矿岩体、成矿带，内含著名的鹿井铀矿田。岩体内产出的铀矿床均属花岗岩中低温热液型铀矿床，铀矿床成因和空间上均与花岗岩体有着密切的关系。诸广山复式岩体规模巨大，为多期次、多阶段的复式岩基，热液活动十分强烈。铀成矿作用主要与印支-燕山期岩浆岩活动有关。铀矿床属于地幔流体成矿作用范畴。与铀矿化有关的热液活动大体可分矿前期、成矿期、矿后期。成矿流体中的铀主要来源于地幔流体在上升过程中与地壳岩石相互作用过程中的浸取。铀矿田均处于区域深大断裂交汇区，铀矿床定位于主干构造交汇处，铀矿体多赋存于次级构造产状的变异部位。在总结该区铀矿床产出的地质背景、铀成矿基本特征和主要控矿因素的基础上，总结了区内铀矿成矿模式，指出了区内主要的铀矿找矿标志和找矿方向，为区内下一步铀矿勘查工作提供借鉴。<br />
Zhuguangshan composite rock mass is located at the junction of Hunan, Jiangxi and Guangdong provinces. It is an important uranium polymetallic metallogenic rock mass and metallogenic belt in China, containing the famous Lujing uranium ore field. The uranium deposits in the rock mass belong to granite medium-low temperature hydrothermal type uranium deposits. The genesis and space of uranium deposits are closely related to granite bodies. Zhuguangshan complex rock mass is a large-scale, multi-stage, multi-stage complex rock base, hydrothermal activity is very strong. Uranium mineralization is mainly related to Indosinian-Yanshanian magmatic activities. The uranium deposit belongs to the category of mantle fluid mineralization. Hydrothermal activities related to uranium mineralization can be roughly divided into pre-mineralization, mineralization and post-mineralization. Uranium in ore-forming fluids mainly comes from the leaching of mantle fluids in the process of interaction with crustal rocks during the ascending process. Uranium ore fields are located in the intersection area of regional deep faults. Uranium ore deposits are located at the intersection of main structures, and uranium ore bodies are mostly located in the variation part of secondary structural occurrence. On the basis of summarizing the geological background, basic characteristics of uranium mineralization and main ore-controlling factors of uranium deposits in the area, the uranium metallogenic model in the area is summarized, and the main prospecting indicators and prospecting directions of uranium deposits in the area are pointed out, which provides reference for the next uranium exploration work in the area.
