摘要: 粤北下庄铀矿田发育五组近似等间距展布的北西西向辉绿岩脉，其与铀成矿关系密切.为查明辉绿岩成因及其与铀成矿关系，通过辉绿岩岩石地球化学、磷灰石U-Pb年代学及成矿期石英H-O同位素分析，结合区域构造背景，系统研究了辉绿岩的成岩时代、成因及其对铀成矿的控制机制.结果表明：（1）辉绿岩形成于两期岩浆活动（200~180 Ma和150~ 140 Ma），分别对应早侏罗世和晚侏罗世；（2）辉绿岩富集大离子亲石元素和强不相容元素；稀土元素球粒陨石标准化配分曲线呈右倾型，无明显Eu、Ce负异常，具有板内玄武岩属性，源于地幔部分熔融并受俯冲流体交代；（3）早期辉绿岩（200~180 Ma）可作为有利的赋矿围岩，与其侵位相关的深大断裂为成矿流体提供通道，断裂与辉绿岩交切部位易于形成交点型铀矿化，其成矿流体具壳幔混合来源特征；晚期辉绿岩（150~140 Ma）不仅继承了早期辉绿岩的作用，还为138~122 Ma阶段的铀成矿提供了地幔流体和矿化剂ΣCO2，促进了碎裂蚀变岩型铀矿化的形成，其成矿流体主要来源于地幔流体.Abstract: The Xiazhuang uranium ore field in North Guangdong is characterized by five sets of approximately equidistant NWW-trending diabase dikes, which are closely related to uranium mineralization. To determine the genesis of diabase and its relationship with uranium mineralization. This study systematically investigates the diagenetic age, genesis of diabase, and its controlling mechanisms on uranium mineralization through geochemical analysis of diabase, apatite U-Pb geochronology, and H-O isotopic analysis of ore-forming quartz, combined with regional tectonic background. Results indicate that: (1) The diabase was formed during two magmatic events (200-180 Ma and 150-140 Ma), corresponding to the Early Jurassic and Late Jurassic, respectively. (2) The diabase is enriched in large-ion lithophile elements (LILEs) and highly incompatible elements. The chondrite-normalized rare earth element (REE) patterns exhibit right-leaning trends and no significant Eu or Ce anomalies, indicating an intraplate basalt affinity derived from partial mantle melting with metasomatism by subduction-related fluids. (3) The early-stage diabase (200-180 Ma) served as favorable host rocks for uranium mineralization. The deep-seated faults associated with diabase emplacement provided pathways for ore-forming fluids, and the intersections between faults and diabase facilitated the formation of vein-type uranium deposits with crust-mantle hybrid fluids. The late-stage diabase (150-140 Ma) not only inherited the role of the early-stage diabase but also contributed mantle-derived fluids and mineralizing agents (ΣCO₂) during the 138-122 Ma uranium mineralization stage, promoting the formation of fractured alteration-type uranium deposits dominated by mantle-derived fluids.
