Tectono-sedimentary analysis of the Lower Cretaceous succession in the sags of the Ondor Sum uplift, Southern Erlian Basin, NE China

The tectonics of continental rift basins and the accompanying deposition processes are areas of increasing research interest. The Ondor Sum uplift is located in the southern Erlian Basin, NE China. It is a promising site for petroleum exploration. In this study, we used 2D and 3D seismic, well-log and core data to conduct a tectono-sedimentary analysis of the sags of the Ondor Sum uplift.
