The Dayangshu Basin located in eastern Inner Mongolia, is one of the key areas for oil and gas exploration in the periphery of Songliao Basin. So far, this basin has been poorly explored, and the basic geological research is still weak, due to the lack of high-quality paleontologic and stratigraphic data. The previous oil and gas investigations were mainly focused on the Early Cretaceous strata. However, the Late Cretaceous Nenjiang Formation in the basin also has hydrocarbon potential according to the latest research. In recent oil and gas geological survey, palynological fossils have been discovered from the Nenjiang Formation in the Dayangshu Basin, providing new evidence for biostratigraphic division and correlation.
