摘要:石角围花岗岩型铀矿床位于粤北下庄铀矿田东部,沥青铀矿是矿床的主要矿石矿物,也是厘定成矿年龄的理想对象。前人采用同位素稀释法(ID-TIMS)和电子探针U-Th-totalPb化学定年法获得的成矿年龄为138~38Ma,但前人年龄变化范围大,可靠性有待考究,难以有效约束矿床的成矿时代。本文利用LA-ICP-MS原位微区分析技术,对石角围矿床矿石中沥青铀矿开展了原位U-Pb定年。研究表明:沥青铀矿的206Pb/238U年龄为52.5~56.9Ma,加权平均年龄为54.7±0.5Ma(MSWD=1.19,n=19)。本次沥青铀矿原位U-Pb定年与前人相比更好地避免了矿物包裹体、后期次生变化、显微裂隙等因素的影响,获得的沥青铀矿原位U-Pb同位素年龄代表矿床的成矿年龄。本研究获得的石角围矿床成矿年龄(~55Ma)与华南花岗岩型铀矿床主成矿期(~50Ma)相一致,指示石角围矿床铀成矿作用与华南岩石圈局部伸展作用下的断裂构造活动密切相关。
