Activation history of the Hutchinson dunes in east-central Kansas, USA during the past 2200years

Climate-driven changes to dune activity during the Last Glacial Maximum and deglaciation in the Mu Us dune field, north-central China

“…Older sands are more likely to have been reworked by later aeolian activity or other processes, such as bioturbation (Halfen et al, 2012). Such effects must almost always decrease the amount of sand per unit area preserved from older episodes of dune activity, wherever there has been substantial later activation.…”

“…The top of these wedges is quite flat, and occurs near the present-day ground surface, or is covered by aeolian sands of one to several meters. Several typical characteristics of their sedimentary structures indicate that these are sand wedges, that is, periglacial thermal-contraction cracks with a primary filling of sand (Harry and Gozdzik, 1988;Murton et al, 2000). The sandstone strata adjacent to the wedges are upturned (Fig.…”

Interpretations and common challenges of aeolian records from North American dune fields

“…In all instances, chronometric information has been placed in a stratigraphic context in relation to the modern surface, buried soil horizons, and changes in sedimentology. In addition, some studies have focused on relatively shallow coring or excavations to obtain knowledge of the most recent episodes of aeolian activity (Wolfe et al, 2001(Wolfe et al, , 2004(Wolfe et al, , 2013Halfen, 2012;Halfen et al, 2012).…”

Synthesis on Quaternary aeolian research in the unglaciated eastern United States

“…Numerous studies have focused on Pleistocene and Holocene inland aeolian deposits, and associated paleosols, in non-desert unglaciated regions of the country. Examples include loess studies in the northwestern USA (Busacca, 1991;McDonald and Busacca, 1992;Busacca and McDonald, 1994;Busacca et al, 2004;Sweeney et al 2004); studies of sand and finer-grained aeolian sediment in the High Plains of the west-central USA (Muhs, 1985;Holliday, 1989Holliday, , 2001Muhs et al, 1999a;Muhs et al, 1999b;Arbogast and Muhs, 2000;Muhs and Holliday, 2001;Forman et al, 2001Forman et al, , 2008Forman et al, , 2009Rawling et al, 2003;Miao et al, 2007;Muhs et al, 2008;Halfen et al, 2010Halfen et al, , 2012, and loess studies in the eastern midcontinent (Fig. 1a) (Ruhe 1969(Ruhe , 1983Barnhisel et al, 1971;Leigh and Knox, 1994;Follmer et al, 1986;Forman et al, 1992;Follmer, 1996;Grimley et al, 1998Grimley et al, , 2003Grimley, 2000;Hall and Anderson, 2000;Muhs and Bettis, 2000;Bettis et al, 2003a,b;Karathanasis and MacNeal, 2004).…”
