| 摘 要： | 文章从粤北地区受南雄断裂带控制的南东侧盆地沉积建造组合、构造岩成分特征等入手,探讨南雄断裂带的发生发展、构造动力演化及不同阶段断裂组合形式和铀矿床区域定位规律,提出与南雄断裂带强烈挤压阶段相配套的北西向张性断裂系统是幔源岩浆作用及其深部热流体侵入通道和铀矿体赋存部位的观点。下一步工作重点应针对北西向张性断裂的隐蔽性特点,选择有效的地球物理和地球化学勘查手段,查明北西向断裂地表出露的确切位置、产状变化及其空间展布规律,配合钻探工程揭露验证,不断深化对区域铀成矿规律的认识,扩大找矿效果。

| Abstract: | By studying the sediment formations in the basin to the southeast of Naxiong fracture belt and the lithologic composition of structre rocks,this paper discusses the the origination and development,evolution of structural dynamics,fracture pattern and locating pattern of uranium deposits.It was suggested that the NW striking tensional fractures matched to Nanxiong fracture belt during the intensely compress periond were the intrusive passageway of mantle magmatism and deep hydrothermal fluid,and the store pl... |
