摘要
Based on the observation,measurement and analysis of two loess-paleosol sequences and fault dislocation in Gaojiagou,Bailuyuan,we obtain stratigraphic division of loess-paleosol sequences and some parameters of fault activity since Middle Pleistocene.The results show that the stratum of S2 and S3 both consist of two layers of paleosol with one layer of loess between them,and the stratum of L7 consist of two layers of loess with one layer of not development paleosol between them in Gaojiagou.Fault activities with spatial difference are always exist in Bailuyuan since Middle Pleistocene.
