摘　　要：本文依据岩性、岩相特征 ,按岩石地层单位的含义和划分准则 ,新创立了龙溪段。龙溪段是泰和盆地晚白垩世晚期形成的一套以洪积相粗—细碎屑岩为主的岩石地层单位 。In light of the definition and classification criteria of lithostratigraphic unit, and based on lithologic and lithofacies characteristics, the authors have newly established a lithostratigraphic unit Longxi Member, which is a suite of rocks dominated by pluvial coarse-fine clastic rocks formed in late Late Cretaceous in the Taihe Basin. Its establishment has provided some important information for the study of the Taihe Basin.
