Anda Formation in the northern Songliao basin and its spore-pollen assemblage |

| Abstract: | A part of the"Dengluoku Formation" in the Songliao basin is separated and renamed the Anda Formation by this paper. The newly established formation is complete in sequence and sedimentary cycles and contains abundant Spores and pollen grains. Its top and base are clearly limited because it yields Cicatricosisporites-Appendicisporites-Gleicheniidiies-Clavatipol-lenites Assemblage. The Anda Formation is comparable with the Mulin Formation in Jixi, the Yingcheng Formation in southern Songliao basin and the Fuxin Formation in western Li-aoning and attributed to the Barremian (Early Cretaceous). |
