The Character and Possible Origins of the Aeolian Sediments of the Wahiba Sand Sea, Oman

Discovery and significance of Quaternary aqueously deposited aeolian sandstones in the Sanhu area, Qaidam Basin, China

“…These sedimentary characteristics overlap with those found in modern aeolian sands from Mingsha Mountain ( Fig. 4c) and suffice to discriminate them from lakeshore facies (Goudie 1987;Hu et al 2001;Russell 2004, 2009;Zhang et al 2011;Bertran et al 2011Bertran et al , 2016. Aeolian horizons of the Qigequan Formation also contain some clay and mica particles apparently transported by the wind and deposited under lacustrine conditions.…”

Source provenance of carbonate grains in the Wahiba Sand Sea, Oman, using a new LIBS method

“…The Wahiba Sand Sea is made up of two major physiographic zones; the Northern and Southern Wahiba, also known as the Upper and Lower sands (Goudie et al, 1987). The Northern Wahiba is a large north-south trending megaridge system (Goudie et al, 1987;Jones et al, 1988;Warren, 1988) whereas the Southern Wahiba, which includes an area called the southwest peripheral sand (Goudie et al, 1987;Jones et al, 1988), consists of a mix of active linear and transverse dunes, nabkha fields, and sand ridges. The Southern Wahiba is thought to represent more recent periods of aeolian activity than the more stabilized megaridges (Warren, 1988;Radies et al, 2004;Robinson et al, 2007).…”

“…The Wahiba Sand Sea in the Sultanate of Oman is an example of a complex provenance setting with potential sand sources including fluvial systems around the dunes, the coastal system, and older, poorly lithified aeolian units underlying the present dunes (Pease and Tchakerian, 2002;Robinson et al, 2007). Despite morphologic and age differences between the northern and southern regions of the dunes (Goudie et al, 1987), the historical view has been that the sand in the dune field was derived primarily from the coast with minor inputs from other sources (Goudie et al, 1987;Allison, 1988;Glennie and Singhvi, 2002). Those arguments have been based on a ubiquitous presence of carbonate grains throughout the dunes, believed to be blown north from the coast by the Southwest Monsoon.…”

Sedimentological, modal analysis and geochemical studies of desert and coastal dunes, Altar Desert, NW Mexico

“…The grain-size parameter hierarchical dendrogram shows a separation of the Pinacate desert dune sands from the rest of the dune sand groups (Figure 9(A)), implying that the El Pinacate group is significantly different from the rest of the dune sands in terms of grain-size parameters. According to Goudie et al (1987), dune sands with longer transport history (far away from the source sediments) may generate dunes with fine-grained sands. Lancaster (1995) reported a fining in the grain size distributions from the northwest to the southeast in the Altar Desert sands.…”
