摘　　要：富饶阶曾经被当做我国陆相白垩系最顶部的一个年代地层单位,在其典型剖面黑龙江嘉荫县乌云地区除见到少许大植物化石外,富含孢粉化石,经过近年不断深入研究,发现它可以和松辽盆地明水组明二段或苏北—南黄海盆地泰州组泰二段的孢粉组合面貌进行对比,其时代为早古新世而不是晚白垩世马斯特里赫特期。The Furaoan Stage was used as the uppermost chronostratigraphic unit of non-marine Cretaceous in China. It is rich in sporo-pollen fossils at its type section in the Wuyan area near the Heilongiiang （A- tour） River. In recent years, through systematic investigation of the Furaoan strata, a rich assemblage of sporo-pollen fossils has been described. This sporo-pollen assemblage allows a correlation with upper member of the Mingshui Formation in the Songliao Basin and upper member of the Taizhou Formation in the South Yellow Sea-North Jiangsu Basin. It suggests an Early Paleocene age, rather than a latest Cretaceous Maastrichtian age.
