The study of marginal areas of Tibetan Plateau, especially gravels, can help to understand and constrain the evolution and mechanism of the uplift of the plateau. In this study, the Cenozoic gravels in the Xiaohonggou section, which is located in the piedmont of Xiangshan, northeast of Tibetan Plateau, has been chosen to conduct gravel counting. Based on the counting data, gravels in the upper segment of Sikouzi Formation, lower and upper segments of Hongliugou Formation, Quaternary and present riverbed, appear to be mainly sandstone and quartz sandstone, which is similar to the lithology in Xiangshan Mountain, indicating that they came from Xiangshan area. It is indicates that there has been a relatively high relief in the Xiangshan, northeast of Tibetan Plateau before the Sikouzi Formation deposited (Eocene).
