“…0.5 Ma (see also Kukla and An 1989), implying stronger summer monsoons during interglacial maxima. Based on analytical results from a drill core retrieved from the central Tengger Desert, Li et al (2014) reported a significant deposition of eolian dust that started at 2.6 Ma with the initial formation of the Tengger Desert at 0.9 Ma and a prevalence of eolian sand deposition similar to the present started at 0.68 Ma. Pollen and organic carbon isotope records from the CLP Wu et al 2007) also suggest a shift to a drier climate at ca.…”

Uplift of the Himalaya and Tibetan Plateau (HTP) and its linkage with the evolution of the Asian monsoon has been regarded as a typical example of a tectonic-climate linkage. Although this linkage remains unproven because of insufficient data, our understanding has greatly advanced in the past decade. It is thus timely to summarize our knowledge of the uplift history of the HTP, the results of relevant climate simulations, and spatiotemporal changes in the Indian and East Asian monsoons since the late Eocene. Three major pulses of the HTP uplift have become evident: (1) uplift of the southern and central Tibetan Plateau (TP) at ca. 40-35 Ma, (2) uplift of the northern TP at ca. 25-20 Ma, and (3) uplift of the northeastern to eastern TP at ca. 15-10 Ma. Modeling predictions suggest that (i) uplift of the southern and central TP should have intensified the Indian summer monsoon (ISM) and the Somali Jet at 40-35 Ma; (ii) uplift of the northern TP should have intensified the East Asian summer monsoon (EASM) and East Asian winter monsoon (EAWM), as well as the desertification of inland Asia at 25-20 Ma; and (iii) uplift of the northeastern and eastern TP should have further intensified the EASM and EAWM at 15-10 Ma.We tested these predictions by comparing them with paleoclimate data for the time intervals of interest. There are insufficient paleoclimate data to test whether the ISM and Somali Jet intensified with the uplift of the southern and central TP at 40-35 Ma, but it is possible that such uplift enhanced erosion and weathering that drew down atmospheric CO 2 and resulted in global cooling. There is good evidence that the EASM and EAWM intensified, and desertification started in inland Asia at 25-20 Ma in association with the uplift of the northern TP. The impact of the uplift of the northeastern and eastern TP on the Asian monsoon at 15-10 Ma is difficult to evaluate because that interval was also a time of global cooling and Antarctic glaciation that might also have influenced the intensity of the Asian monsoon.

“…Based on geological evidence, the Taklimakan Desert was probably formed during the late Miocene to early Pliocene (Sun and Liu, 2006;Sun et al, 2009;Liu et al, 2014); however the northern Chinese deserts were formed during the Quaternary, e.g., the Tengger Desert formed at $0.9 Ma (Li et al, 2014) and the Badain Juran Desert formed at 1.1 Ma (Wang et al, 2015). In addition to these deserts, the progressive drying-up of rivers and lakes probably played an important role in contributing dust to the Chinese Loess Plateau (Stevens et al, 2013;.…”

“…Quaternary sediments that surround the desert (Li et al . ) are the source material for dune formation. Sedimentary analysis indicates that the initial formation the desert started by ∼0.9 Ma, and the domination of aeolian sand in strata with similar characteristics of the modern desert appeared by ∼0.68 Ma (Li et al .…”

Grain‐size characteristics of dune networks in the Tengger Desert of northwestern China were investigated. Grain‐size parameters (mean, standard deviation, skew, and kurtosis) were determined on dune surfaces at windward toe, stoss, crest and leeward toe locations. Multiple discriminant analyses were applied to distinguish deposition environments. Results indicated that the aeolian sediment is mainly composed of very fine and fine sand in the dune networks of the Tengger Desert. Sorting improves as grain size becomes finer. However, the relationships between mean grain size, skew, and kurtosis vary in space. There is a negative relationship between skew and sorting; similarly, the relationships between sorting and skew, and skew and kurtosis change in space. The sediment deposition environment includes aeolian sediment and lacustrine sediment. The lacustrine sediment provides the source material for dune windward toe and stoss formation and development, but the aeolian sediment provides the source material for dune crest and leeward toe formation and development. According to the log‐probability of grain size distributions, aeolian sediments in dune networks are composed of two distinct saltation populations.
