The authors studied the source direction of the Upper 4th Member of Shahejie Formation in Shengtuo area in such aspects as palaeo-geomorphologic analysis, lithic fragment type of sediments, proportion of sandstone and characteristic element type, and distribution studies from seismic, logging and geochemical data. According to the result, the authors point out that the source of the Upper 4th Member of Shahejie Formation was derived from the uplifted side directly.
