摘要
China Cretaceous Continental Scientific Drilling (CCSD) in the Songliao Basin, called SK1 project, collected 295.53 m of the lower members 1&2 of Nenjiang Formation which correspond to the late Santonian to early Campanian. The authors described the sedimentary sequence, lithology, lithofacies and cyclic stratigraphy at the drilling spot in cm-scale. Twelve litho-types were recognized in the section. The new found evidences are very important to interpret basin evolution features such as lake anoxic, source rock development and the potential linkage between lake and adjacent sea.
