“…Given these deserts are located in the northeast part of the studied region (such a positional relationship is discrepant with the prevailing wind direction), and the formation of these deserts was later than the XSZ red clay (Lu et al, ), we deduce that the Ordos deserts are less likely to contribute to the NE TP red clay. Therefore, we infer that the XSZ red clay sediments are mainly derived from the Tarim Basin and Qilian Mountains in the NTP, which is consistent with the zircon U‐Pb ages of red clay in the western CLP (Shang et al, ). Furthermore, the materials of the Tarim basin contributing to XSZ and YJ red clay were mainly derived from the surrounding mountains in the NTP, which indicate the NE TP red clay might be ultimately derived from the NTP.…”

“…Much research attention has been directed to the Chinese Loess Plateau (CLP), and comprehensive investigations have been made of the origin of the red clay and the overlying loess‐paleosol sequence (Bird et al, ; Chen & Li, ; Li et al, , ; Nie et al, ; Shang et al, ; Sun, ; Sun, Tada, et al, ) and their paleoclimatic record (An et al, ; Ding et al, , ; Qiang et al, ; Vandenberghe et al, ; Zan, Fang, Li, et al, ; Zan, Fang, Zhang, et al, ; Zhang et al, ). Several primary conclusions have been drawn: (i) The ultimate source materials of these eolian sediments are the northern TP (NTP) and the Central Asian Orogen (CAO), and shifts in these sources were determined by processes of mountain erosion within the two regions, and by desertification processes in the Asian interior (Chen et al, ; Chen & Li, ; Fan et al, ; Li et al, , , ; Nie et al, ).…”

“…(ii) The winds transporting the red clay were weaker than those associated with the deposition of the loess‐paleosol sequences; in addition, the influence of the paleo‐East Asian Monsoon (EAM) on the CLP from the Miocene to Pliocene was not as strong as that since the Quaternary (An et al, ; Ding et al, ; Li, ; Li et al, ; Li, Fang, et al, ; Qiang et al, ; Vandenberghe et al, ). However, the specific source regions and the variations in these two categories of eolian sediments are controversial (Bird et al, ; Chen & Li, ; Shang et al, ; Sun, ; Wang et al, ). For example, some have claimed that the loess‐paleosol sequences are closely linked with the alluvial sediments of the Yellow River (Bird et al, ; Stevens et al, ), whereas others have regarded the Gobi and sandy deserts as the dominant sources (Chen et al, ; Chen & Li, ; Li et al, , ; Sun, ).…”

The red clay and loess‐paleosol sediments of the Xiaoshuizi and Halagu planation surfaces of the northeastern Tibetan Plateau (TP) provide insights into the response of paleo‐atmospheric circulation and surface processes to TP uplift and global climate changes. We present silicate Sr‐Nd isotope compositions and bulk sediment grain‐size parameters of the red clay and loess‐paleosol sequences, with the aim of reconstructing changes in the transporting wind systems and sediment source regions. The results indicate that the red clay on the planation surface was transported mainly by the westerlies from the Tarim Basin and the Qilian Mountains, while the loess‐paleosol sediments were transported mainly by the East Asian winter monsoon (EAWM) from the Badain Jaran Desert, Tengger Desert, and Qaidam Basin. These shifts in transport mechanism and source were likely related to major changes in the topography of the TP and the expansion of Northern Hemisphere glaciation since the Middle Pliocene. In addition, we reconstructed the evolution of the paleo‐atmospheric circulation from the Late Miocene to the Middle Pliocene. During the Late Miocene, both the paleo‐EAWM and East Asian summer monsoon (EASM) were weak, and westerly winds dominated the climate of the study area. During the Early Pliocene, both the paleo‐EAWM and EASM exerted an increasing influence on the study area. We ascribe the slight enhancement of the paleo‐EAWM to the gradual growth of the northern TP and the significant enhancement of the paleo‐EASM to global climate changes.

“…In addition, work on the origin of the Loess Plateau has revealed that a genetic link exists between the Yellow River and associated fluvial systems and the formation of the loess deposits on the Loess Plateau (Stevens et al, 2013;Bird et al, 2015;Shang et al, 2016;Licht et al, 2016). Additionally, a recent study revealed that the sediments of the western Mu Us Desert and the Loess Plateau originate from Yellow River alluvium that was deposited in the Yinchuan-Hetao Graben, and was subsequently redistributed by winter monsoon winds after 3.6 Ma (Nie et al, 2015).…”

Reconstructing the Cenozoic environmental history of Hetao Basin, in the northern part of the Ordos Plateau in North China, is important not only for revealing the evolution of the Yellow River, but also for understanding the formation of the Hobq Desert. Here we present the stratigraphic framework of drill core DR01 with length of 2503.18 m, and the results of magnetostratigraphic and ESR dating and multi-proxy analyses of drill core WEDP05 with length of 274.60 m, from the Hetao Basin. The magnetostratigraphic and ESR results indicate that core WEDP05 spans the last ~1.68 Ma. Stratigraphic sequence of core DR01 indicates that the Hetao area was uplifted and eroded during the early Cenozoic, before subsiding to form a sedimentary basin. Subsequently, the basin was a fluvio-lacustrine environment during the Pliocene and then experienced alternating desert and fluvio-lacustrine conditions during the Quaternary. Sedimentary facies and multi environmental-proxy analyses of core WEDP05 indicate that the basin was occupied by a fluvio-lacustrine system during the following intervals: ~1.47-~1.30 Ma, ~1.17-~1.07 Ma, ~0.68-~0.60 Ma and from ~0.47 Ma to the last interglacial; and that a desert environment developed during the lake regression phases of ~1.30-~1.17 Ma, ~1.07-~0.68 Ma and ~0.60-~0.47 Ma. The presence of aeolian sand at the base of core WEDP05 suggests that the origin of the Hobq Desert can be traced back to the early Pleistocene, and resulted from the erosion and transportation of exposed fluvio-lacustrine sediments by near-surface winds associated with the Asian winter monsoon. A large river channel in the Hetao Basin may have existed as early as the Pliocene, which was 3 occupied by the Yellow River when its upper reaches formed by at least ~1.6 Ma. Subsequently, at least since ~1.2 Ma, the Yellow River formed its drainage system around the Hetao Basin and controlled the paleoenvironment evolution of the basin.

End-member modeling of the grain-size record of Sikouzi fine sediments in Ningxia (China) and implications for temperature control of Neogene evolution of East Asian winter monsoon

The Late Cenozoic East Asian winter monsoon (EAWM) enhancement has been attributed to several factors, such as uplift of the Tibetan Plateau, retreat of the Paratethys Sea, and global cooling related to polar ice volume increment. However, the fundamental forcing factors remain enigmatic due to the absence of long and continuous climate records and sensitive indicators. Here we reanalyzed the published grain-size record of Sikouzi fine sediments in the western Chinese Loess Plateau through end-member (EM) modeling. The results indicate that EM 2 with grain-size peaks between 10–100 μm decreased in content from 20.1 to 17 Ma and stepwise increased from 17 to 0.07 Ma during the following six stages (17–15 Ma, 15–12 Ma, 12–8 Ma, 8–6 Ma, 6–4 Ma and 4–0 Ma). Such varying trends can be successively correlated in seven stages with the integrated benthic δ18O record, implying that global warming weakened the EAWM from 20.1 to 17 Ma and global cooling has stepwise strengthened the EAWM since 17 Ma. Therefore, we conclude that global temperature change played a major role on the evolution of EAWM during the Neogene period. By contrast, Late Cenozoic palaeogeographic reorganization caused by uplift of the Tibetan Plateau and retreat of the Paratethys Sea contributed less to the evolutionary evolution of EAWM. Spectral analysis of the EM 2 data first provided direct evidence of orbitally influenced deposition in the study area and thus the EAWM variations during the Neogene period. The 100-kyr period became weak since ~10 Ma, possibly due to the decrease in sensitivity of a more stable, continental-scale ice sheet in Antarctica to local insolation forcing, deserving further investigation.
