Abstract: The Honggucheng Formation lies in the Upper Lower Cretaceous in the Minghe basin, which is like multistory type and cyclic sequences resulting from multiple flood processing deposition. It is characterized by the interchange of structure underwater and exposure structure. The scales of early and later flooding exist difference,which shows that they were formed in depositional environments of shore lake and depression on banks.Combined with the analysis of environment-facies and process-facies, the features of deposition and tectonic background of the Honggucheng Formation are studied deeply,which illustrates that Hongguchenng Formation is the result of the basin's accelerated shrinking period during basin evolution. The environment facies and process-facies are two important contents of the nonmarine basin analysis.
