| Abstract: |
| Based on the principle of sequence stratigraphy and seismic geomorphology, an analysis of seismic geomorphology is successfully applied in reconstructing the depositional system of the Upper Permian Changxing marine carbonate rock at some study area in the northeast part of Sichuan Basin. Base on regional geological information and synthetic seismogram, a seismic paleogeomorphic map is acquired by means of determining the time-equivalent sequence framework and surfaces, flattening layers and extracting the strata slices along the time-equivalent top boundaries of Changxing Formation. After transformation of seismic facies to depositional facies, the characterization of Changxing depositional plane distribution is depicted. |
