The core of the theory of resolution sequence stratigraphy refers to the redistribution of the sediment volume in the same sedimentary system domain due to the change in the ratio of the volume of the sediment to the recharge flux of the sediment (ais) during the change of the base level cycle , Resulting in changes in sediment stacking style, facies type and phase sequence, rock structure, and preservation degree. The Xingouzu Formation in the central and southern Jiangling Depression is the research object, using high-resolution sequence stratigraphy theory and methods to study the deposition of the area Based on the background, combined with core, logging and seismic data, the Xingouzu Formation formations are finely compared and divided

The theoretical core of the determination of stratospheric stratigraphy refers to the redistribution of sediment volume in the same sediment system domain due to the change of sediment capacity space and sediment resupply flux ratio (ais) in the process of rotation change of the surface, resulting in changes in sediment build-up style, phase type and phase sequence, rock structure, preservation degree, and the new trench group in the south-central part of Jiangling depression, using the high-resolution stratospheric formation theory and method, based on the study area, To make fine comparison and division of the formations of the new ditch tsui group

The theoretical core of resolution sequence stratigraphy is that in the process of base level cycle change, due to the change of the ratio of sediment accommodation space to sediment supply flux (AIS), the redistribution of sediment volume in the same sedimentary system tract results in the change of sediment stacking style, facies type, facies sequence, rock structure and preservation degree. Xingouzui Formation in the south central part of Jiangling depression is under research Based on the sedimentary background of the study area, combined with core, logging and seismic data, the strata of Xingouzui Formation are finely correlated and divided by using the theory and method of high-resolution sequence stratigraphy<br>
