摘　　要：本文沿用263地质队资料,将南雄红层底部出现的第Ⅰ沉积旋回划为松山组;重新厘定了南雄群的含义,阐明其间各岩石地层单位顶、底界线标志;沿用罗佛寨群;指出不必用丹霞群(组)表示南雄盆地边缘相的粗碎屑岩层,并认为丹霞盆地的丹霞组相当于南雄盆地的园圃组下段,建议南雄盆地弃用丹霞群(组)一名。在此基础上提出,粤北地区白垩系—古近系岩石地层序列是由松山组,南雄群(园圃组、主田组、浈水组),罗佛寨群(上湖组、浓山组、古城村组)组成。In the present paper, the sedimentary cycle Ⅰ at the bottom of the Nanxiong Red Bed has been classified as the Songshan Formation, and the Luofozhai Group has been redefined according to the data provided by the No. 263 Geological Party. The limits of Nanxiong Group have been revised through the classification of the boundaries of various formations in it. The Danxia Group （Formation） cannot be used to define the coarse clastics along the margin of the Nanxiong Basin. The Danxia Formation in the Danxia Basin is correlatable with the Lower Member of Yuanpu Formation in the Nanxiong Basin. The Danxia Group （Formation） therefore cannot be used in the Nanxiong Basin. The Cretaceous-Paleogene lithostratigraphic sequence in northern Guangdong Province is composed of Songshan Formation, Nanxiong Group （Yuanpu Formation, Zhutian Formation, Zhenshui Formation） and I.uofozhai Group （Shanghu Formation, Nongshan Formation, Gucheng Formation）.
