This cross-bedding is wind-induced and plate-like with a length of about 30m and a height of about 10m. It appeared in the late Pleistocene of the Quaternary period about 126,000 to 11,000 years ago. The cross-bedding is large, and the thickness up to 2.5m. The inclination of the fine layer is relatively large which is generally 22 to 25°and up to 30°. The tendency of the fine layer changes greatly, indicating the different ancient wind directions. The “paint” of sand grains can be observed under the microscope, indicating that the cross-bedding was caused by wind instead of flowing water. The sand layer is covered with a river alluvium about 20cm thick. Clear ripples were seen between the layers. The wave is 15cm long and 2cm high, indicating that the sand dunes were submerged by current in the later period. The Aeolian Cross-bedding reveals the local palaeoclimatic changes between the glacial-interglacial periods in the area.
