“…During this incision phase of the cold-warm transition and the subsequent warm interglacial, the abandoned terrace was invaded only at high stages of the river, and recorded flood deposits of different lithologies due to different flood intensities. Such a succession seems to be analogous to other terraces in the Hanzhong Basin and Huanghe (Yellow River) catchment (Pan et al, 2011; Vandenberghe et al, 2011; Wang et al, 2015; Gao et al, 2020). The style of alluvial architecture (overall dominant, vertical fine-grained accretion with small bars, small-scale cut-and-fill channels, distinct channel migration, and bank erosion) shows many similarities with the active meandering Rio Bermejo in Argentina described by Smith et al (2016).…”

This paper describes an assemblage of diverse floodplain facies of reworked loess (facies b, c) in a Middle Pleistocene monsoonal setting of the Hanzhong Basin, central China. The vertical and lateral sedimentary sequences show changing energy conditions. Apart from the highest energy in the channel facies (facies a), a relatively high energy floodplain environment (facies b) prevailed in waterlogged conditions, with small, laterally migrating (sub)channels. Facies b generally interfingers with aggrading horizontal sheets of overbank deposits in alluvial pools and swamps in a floodplain with much lower energy (facies c), in which phases of stability (soil formation) occasionally interrupted overbank deposition. Reworked loess forms the main part of the floodplain deposits. The paleosols are considered to have been formed under low hydrodynamic conditions in an interglacial environment. These interglacial conditions follow the commonly assumed glacial conditions of channel facies a. The sedimentary successions in the floodplain show a recurrent composition and cyclicity between wet and dry floodplain sedimentation terminated by stability with soil formation. The cyclic rhythm of stacked high- and low-energy floodplain sediments is attributed to varied intensity of different hydrodynamic flooding events that may have been due to changing monsoonal rainfall or simple intrinsic fluvial behavior.

“…The burial age of the basal gravel layers has not yet been constrained for terraces T4 and T3. However, recent studies indicate that the incision was a rapid process (Gao et al, 2020), and therefore the age of terraces T5 and T4 can be used to constrain the timing of the start of aggradation. The aggradation of the deposits of terrace T4 may have continued from late MIS 6 to the middle of MIS 5 (Figure 5), corresponding to the late penultimate glaciation (Zhou et al, 2002), and to a subsequent wetter interval (Sun et al, 2019).…”

“…Previous results have demonstrated the usefulness of fluvial terraces for deconvolving the effects of climate and tectonics on incision (Bridgland, 2000;Pan et al, 2009). However, the role of climate and tectonics on the spatial and temporal distribution of terrace deposits remains unclear (Gao et al, 2020;Holbrook & Schumm, 1999;Scharer et al, 2006;Vandenberghe, 2015). The greatest challenge for resolving these issues arises from the difficulty in interpreting terrace records from regions where climate changes are superimposed on spatial and temporal variations in tectonically driven rock uplift (Pan et al, 2009).…”

The relationships between tectonics, climate and sedimentation are important for understanding landscape evolution. In order to elucidate these relationships, we conducted a detailed survey of the thickness of terrace deposits and the altitude of terrace surfaces along the Liyuan River valley, in the Northeast (NE) Tibetan Plateau. We have dated the formation ages of terraces T3 and T4 to 42 ± 3.2 and 93.7 ± 7.5 ka, respectively, using optically stimulated luminescence (OSL) method. By compiling the deposit thickness of terraces, palaeoclimate records and local tectonism, we found that variations in precipitation account for the temporal differences in thickness/ rates of sediment deposition in terraces T4 and T3. However, the spatial distribution of terrace deposit thickness was determined by tectonism, including faulting and folding, which changed the local base level. In order to maintain a foreland-warddipping gradient, the Liyuan River adjusts its sedimentary processes via spatially differentiated aggradation.
