The researchers studied the sediment types in the Nanpu No. 3 area to help with oil and gas exploration. They looked at core samples, seismic data, and more to understand how different sediment systems developed over time. They found that the materials came from the southwest, and fan deltas and shallow lakes formed during certain time periods. The sediment systems changed over time, with multiple layers forming on top of each other. The shape of the lake basin and other factors influenced how the sediments were deposited. This study created a model to show how sediment filled the area, considering things like tectonic activity and water depths.
