摘　　要：华南红层与铀矿化具有密切的时空关系,它们形成于白垩纪—古近纪的拉张构造背景,红盆受后生断裂构造(新构造)控制,是构造残留盆地。产于红盆附近的矿床(田)曾被红层覆盖,红层附近和红层深部是有利于矿化保存的区域,是找矿方向之所在。The uranium mineralization in South China is closely associated with red beds in time and space, which occurs in tensile tectonic setting in Cretaceous and Eogene. The red basins are tectonic remnant controlled by late faults （new structure）. The uranium deposits （field） near red basins were ever covered with the red beds. The vicinity and deep part of red beds are advantageous for uranium ore conservation hence it is where the exploring target lies.
