“…Non-confined sheet-like flood flows are typical, especially in the immediate aftermath of rainstorms. High-magnitude rainfall events, catchment area and relief, the low infiltration capacity of the substrate, the short run-off length from catchment to receiving basin the lack of appreciable relief on the basin plain, and the general absence of dense vegetation cover that might otherwise act to subdue run off, are all factors that contribute to sheet-like floods over large areas (Blair and McPherson, 1994;Blair, 1999;Arzani, 2005;Goudie, 2013). Such non-confined flows typically pass into dune fields penecontemporaneously along multiple open interdune corridors with access gained from multiple points along the dune-field margin.…”

“…The Taklamakan Desert (Figure ) is an important source of global dust (Williams, ) and hosts the largest sand sea (~330,000 km 2 in area) in the midlatitudes (Goudie, ). Thus, sediment provenance of the desert is a key issue in understanding its aeolian system.…”

Sediment provenance is a key issue in understanding the aeolian system of the Taklamakan Desert, an important source of global dust and the largest sand sea in the midlatitudes worldwide. In provenance research, it may be a mistake to assume that the sand and dust fractions of desert sediments have the same source, which has been the case in previous studies of the Taklamakan Desert. The aims of the present study were to identify the provenance of the sand and dust fractions of the sediments of the Taklamakan Desert, to determine the contemporary sediment supply mechanisms of the desert, and to assess the relative importance of silt‐producing mechanisms for the desert dust. We analyzed the grain size of desert sediment samples and measured the content of major, trace, and rare earth elements within the bulk samples, sand fractions (>63 μm), and dust fractions (<63 μm). Our grain size and geochemical data sets suggest that the Kunlun Mountains are the main source of the sand fraction, whereas both the Kunlun and Tian Shan Mountains are the main sources of the dust fraction. Our interpretation is supported by the elevation gradient within the Taklamakan Desert and by wind data.

“…Desert pavements are typical geomorphological features in arid environments (Goudie, 2013). They are composed of a monolayer of clasts at the surface, associated with an underlying unit of eolian fines (sandy silt), which exhibits a several centimeter thick foamy pore structure directly beneath the clasts, the vesicular horizon (Springer, 1958;McFadden et al, 1998;Anderson et al, 2002;.…”

Desert pavements are widespread landforms of arid environments. They consist of a monolayer of clasts at the surface, associated with an underlying unit of eolian fines. In some situations, buried desert pavements can be observed, which is interpreted as a change in the environmental conditions. Therefore, it is believed that desert pavements represent important paleoenvironmental sediment archives, especially for arid environments, where natural archives of past environments are rare. To better understand the formation process of desert pavements and to enable the paleoenvironmental interpretation of these valuable sediment archives, reliable chronologies are of crucial importance. Thus, OSL dating was applied to samples from well-developed desert pavements in two different study areas, the Cima Volcanic Field, eastern Mojave Desert, USA, and the desert of northeastern Badia, Jordan.To test the suitability of the sediments for OSL dating, the luminescence characteristics of the fine-and coarse-grain quartz fraction are described and compared. Finally, first OSL ages are presented.2
