本文将南雄红层底部第Ⅰ沉积旋回划分为松山组，根据第263地质队提供的资料，重新划分了罗佛寨群，通过对南雄群各建造界线的划分，重新厘定了南雄群的界线，丹霞群（组）不能用来划分南雄盆地边缘沿着的粗碎屑岩，丹霞盆地丹霞组与南雄盆地袁铺组下段是可划分的，丹霞群广东北方地区古近系岩石地层层序由松山组、南雄群（袁浦组、竹田组、镇水组）和罗佛寨群（上湖组、弄山组、古城组）组成。
In the present paper,the sedimentary cycleⅠat the bottom of the Nanxiong Red Bed has been classified as the Songshan Formation,and the Luofozhai Group has been redegined 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 Luofozhai Group(Shanghu Formation,Nongshan Formation,Gucheng Formation).
