摘要

摘要: 粤北诸广南铀矿聚集区位于南岭诸广山岩体中东部，区内铀矿资源丰富，是中国重要的铀矿产基地。区内以发育花岗岩型铀矿化为主，整体上受中生代区域性岩浆—构造—热液活动"三位一体"联合控制。区域性花岗质岩浆活动对铀矿化有着预富集作用，断裂构造活动为成矿提供了有利空间，热液活动促使了花岗岩中铀的活化迁移和富集成矿。研究区的铀成矿作用具有同时性和多期性特征，形成于华南白垩纪—古近纪岩石圈伸展动力学背景下，统一受制于地壳的强烈拉张作用。由诸广山岩体与南雄盆地组成的盆山体系的白垩纪—古近纪构造演化可能是导致诸广南铀矿聚集区形成的重要因素之一。

Abstract: The southern Zhuguang uranium ore-concentrated district, which is located in central-eastern part of Zhuguangshan complex in Nanling region, China, is an important producer of uranium resource during the past three decades. There is abundant granite related uranium deposits that are generally controlled by the Mesozoic regional magmation, tectonic activity and hydrothermal events in study area, namely "trinity". The Indosinian and Yanshanian magmatism makes uranium preconcentration in crust of Zhuguang area; the tectonic activity provides a favorable location for uranium mineralization; and the hydrothermal activity drives the uranium migration and ore-formation in altered granite and silicified fracture zone. The uranium mineralization in Zhuguang area is characterized by synchronism and multiple stages, and restrained by the crust extension during the Cretaceous Paleogene lithospheric extension in South China. The Cretaceous Paleogene structural evolution of Nanxiong basin and Zhuguangshan complex is possibly responsible for the large scale uranium mineralization in Zhuguang area.
