The present study aims to unravel more evidences for the megadune formation by testing evidences that exhibit similar mobility with other common dunes. Nature 406:5659, Bristow CS, Duller GAT, Lancaster N (2007) Age and dynamics of linear dunes in the Namib Desert.

The tallest megadunes on the Earth are developed in Chinas Badain Jaran Sand Sea, as a result of which a prolonged curiosity exists with regards to the existence and migration of such large dunes. Formation and Evolution of the Holocene Massive Landslide-Dammed Lakes in the Jishixia Gorges along the Upper Yellow River: No Relation to China's Great Flood and the Xia Dynasty. The longest known parabolic dune has a trailing arm 12 kilometers long. The crest length ages indicate that the modern active dune field began to form at about 2075 ka BP, the dunes in the southeast and northeast are older than those in the western. 251, 106737. doi:10.1016/j.quascirev.2020.106737, Wilson, I.

Details of the experimental processes are described in Supplementary InformationS4. Hence, commonly implemented monitoring methods such as topographic survey and comparison of remote-sensing images fail to reveal the movement of these megadunes.

History and mechanisms for the expansion of the Badain Jaran Desert The Gobi Desert, Badain Jaran Desert (BJD), and the Chinese Loess Plateau (CLP, Fig. The annual dose rate of cosmic ray was calculated based on the parameters and equations proposed by Prescott and Hutton (1994). This research was funded by the Fundamental Research Funds for the Central Universities (GK202103144). The Badain Jaran Desert (BJD) and surrounding deserts are the main sources of sand and dust storms in Asia. These layered sandstone mountains in China look like they are made of pressed crayons. The primordial underlying landforms of gobi deserts are alluvial fans, playas, and wadis, and the dominant sediment sources are the adjacent Gobi Altai Mountains, the Heihe River, and the highlands of southern Mongolia, which are transported by intermittent floods from the upper Pleistocene to the early Holocene21,22. Consequently, it is hypothesized that the relationship between movement rate and dune height should be exponential rather than linear (Sarnthein and Walger, 1974). Long, J. T., and Sharp, R. P. (1964). ), with the knowledge of the age of BJD (Supplementary InformationS11), the experimental and statistical results showed that under the modern wind regime the Gobi Desert could provide nearly all sand sources for the BJD formation. The reversed slipface partly offsets megadune advancement, though it cannot alter the general advancement as it consumes energy for the prevailing northwestern wind to adjust the slipface. Der olische Sandstrom aus der W-Sahara zur Atlantikkste. ADS Sun, Y. et al. However, little is known regarding the movement of megadunes. the best experience, we recommend you use a more up to date browser (or turn off compatibility mode in Observed local air circulation that radiates from the interdune lakes (based on the unpublished data collected from wind towers). TABLE 1. Geol. Paris, France: Bulletin: Institut Franaise de l'Afrique Noire. Like Atlas Obscura and get our latest and greatest stories in your Facebook feed. Recent observations reveal that the megadune-lake system exists as a unique local air circulation with radiation of wind from lake throughout the year (Figure 3, unpublished data), resulting climbing sands on the slipfaces, retarding advancement, and heightening of megadunes.

We selected 90125m quartz grains by wet sieving as the target measuring particles. It is assumed that the similarity between megadunes and dunes should be implied in various aspects besides morphology. (London: Hodder and Stoughton 1943).

The Badain Jaran desert in western Inner Mongolia in China has a unique landscape that contains 72 lakes, with a total water surface area of 23 km 2, and the world's highest stationary sand. Quaternary dust source variation across the Chinese Loess Plateau. Because most datasets started after 1960, only the wind records from 1960 to 2015 were used to evaluate the temporal variation in the aeolian transport potentials. Science Press, Beijing, Wang ZT, Tao SC, Xie YW, Dong GH (2007) Barchans of Minqin: Morphometry. Earth-Science Rev. Aeolian geomorphology has always attempted to understand the formation mechanism of aeolian bedforms that are organized into a hierarchical system consisting of ripples, dunes, and megadunes (i.e., large bedforms with a spacing exceeding 500m and a height reaching 200 or 300m and may occur as linear, crescentic, or star forms) (Wilson, 1972; Goudie, 2004; Livingstone and Warren, 2019). They are a geographical anomaly that has been fascinating visitors for years. (2009). doi:10.1038/432459a. Previous observations in Figure 5 only represented dunes lower than 100m. It is suggested that larger dunes seem to reach a plateau in their rate of movement beyond which the size has no role. These dunes typically have major and minor slipfaces oriented in opposite directions. The European Physical Journal E 42:42, Parteli E, Kroy K, Tsoar H, Andrade J, Pschel T (2014) Morphodynamic modeling of aeolian dunes: Review and future plans. It is therefore deduced that wind is predominantly responsible for the development of megadunes in the Badain Jaran Sand Sea. Hua Zhao Sand dunes up to 400 m high are common in the Badain Jaran Desert in China, but how and why mega-dunes grow remains unclear. Front.

Equivalent dose of quartz originating from ceramics was obtained by OSL single aliquot regenerative dose (SAR) method, measured at 260C of preheat and 220C of cutheat. Shantou University Abstract The coexistence of megadunes and interdune lakes is a unique landscape in the Badain Jaran Desert. Many sand belts with an orientation of NW-SE, which is similar to that of the prevailing sand-transporting winds, connect the BJD with the TD and UBD, forming .

Genetic linkage between the Yellow River, the Mu Us desert and the Chinese Loess Plateau. The Late Holocene dune reaction stage in the arid regions of China (Yang, 2001), and the factors that influence megadune advancement can be considered relatively stable so that dune advancement rate did not vary widely with time (Figure 4). PubMed Central The large size of megadunes and the wind regime are largely responsible for the slow advancement rate of the megadunes in the Badain Jaran Sand Sea. (1980). Nature 432, 459460. Meas.

Formation and evolution of the Badain Jaran Desert, North China, as More research is being conducted to verify the source of the water, as well as their rate of evaporation, or in some cases, disappearance. Despite this presence of groundwater, however, most of the lakes have a high level of salinity. Want to Visit? However, this deduction regarding the formation of megadune requires further evidences.

Other researchers point to factors such as precipitation and snow-melt in certain areas, given that Inner Mongolia Autonomous Prefecture faces intense winters. Lou, T. (1962). Two necessary. doi:10.3969/j.issn.10017410.2009.04.16. About half of that area gives rise to megadunes that tower between 200 to 300 meters (660 to 980 feet) tall. Stavrianos, L. S. A Global History (Ed. Dong, Z., Qian, G., Luo, W., Zhang, Z., Xiao, S., and Zhao, A. It is suggested that megadunes experience similar advancement as the commonly observed sand dunes; the rate of advancement of megadunes fits the rate-height relationship. Introduction The Badain Jaran Desert, part of the Alashan Desert, is the second largest dunefield in China. OSL dating Pattern of mega-dune growth 1.

Badain Jaran DesertTowers of Sand and Lakes Geophys. (2009). Their primary slipfaces are oriented towards the southeast in response to the dominant northwestern wind, and secondary slipfaces are oriented towards the northwest in response to the secondary southeastern wind (Dong et al., 2004). New views on the role of bedform interactions within a set of boundary conditions. Reaching over 1,600 feet tall, they are roughly the same height as the. However, our understanding regarding the mechanism of aeolian bedforms is limited to selected dune types, typically barchan and linear dunes (Rozier et al., 2019; Qian et al., 2021). Secondly, the Nuoritu megadune and Badain Jaran megadune demonstrate similar variation trend in advancement rate for the same period.
