Abstract

Abstract

The interaction of fluvial geomorphology evolution and special geological environment in horizontal formation in Wanzhou district resulted in its unique stepladder geomorphic feature. Based on a systematic field investigation, exploration and data collection, combining with the drilling at Shanwan pond in 2008, we conducted a comprehensive study of its sediment for the first time, systematically collecting sediment samples, doing analysis to determine its age and composition. It shows the consistency of Shanwan cliff collapse and the regional tectonism. The sediment profile of Shanwan landslide collapse deposit at each stage is presented and it is divided into 10 cycles of failure. Combining with the sediment dating, the deposition rate of Shanwan landslide sediment is researched, and the recession rate of Shanwan cliff is proposed as 0.31-0.37 m/ka.
