| Abstract: | Using the sequence stratigraphic theory and methods, an analysis of the sedimentary environment, sedimentary facies and terrestrial facies of sedimentary system tract of the sedimentary formations of the Cretaceous terresterial strata in the northeastern Hefei Basin is made. According to the filling succession of sediments and basic sequence of red bed basin, the filling depositional succession in the Cretaceous fault basin is divided into four sequences. Based on the sequence stratigraphic analysis and temporal and spatial distribution characteristics of lithostratigraphic units and sedimentary system, the stratigraphic framework of the red basin is roughly set up. |
