摘　　要：根据最新的地质调查成果,按岩石地层单位的命名原则,对江西信丰大塘盆地上白垩统进行了重新划分,建立了盆地相应的岩石地层单位。本文阐述该地层序列中段长岗群及其横坑里组、窑前组、新仓下组的建群、建组理由,描述其正层型剖面及含义特征,并对其时代进行讨论。Based on the most recent results of geological survey and on the principle in naming lithostrati graphic units,the Late Cretaceous strata of the Datang basin in Xinfeng,Jiangxi have been re-classified and the correspondent lithostratigraphic units have been established.The authors give reasons for establishment of the HengKengli Formation,the Yaoqian Formation,the Xincangxia Formation and the Changgang Group for the mid-dle section of this Stratigraphic sequence,describe the meaning and characteristics of the holostratotype cross section and supplementary cross section,and finally discuss their ages.
