| Abstract: | Based on field landscape investigations, thermoluminescence (TL), magnetostratigraphy and loess-paleosol sequence, we found
that there are at least four Yellow River terraces, whose ages are 0.86 Ma, 0.62 Ma, 0.13 Ma and 0.05 Ma, in Yuxi Fault-Uplift
(from Sanmen Gorge to Mengjin) and at least three Yellow River terraces, whose ages are 1.24 Ma, 0.25 Ma and 0.05 Ma, in Huabei
Fault Depression (from Mengjin to Kouma). All the terraces have a similar structure that several meters of paleosols directly
develop on the top of fluvial silt. It shows that the Yellow River incised and consequently abandoned floodplain converted
to terrace during the interglacial period. Therefore, there may be a link between the formation of terraces and glacial-interglacial
climatic cycles. However, the differences in the Yellow River terrace sequences and ages between Yuxi Fault-Uplift and Huabei
Fault Depression indicate that the surface uplift should play an important role in the formation of these terraces.
