Abstract: The dispersal of human populations out of Africa into Arabia was most likely linked to episodes of climatic amelioration, when increased monsoon rainfall led to the activation of drainage systems, improved freshwater availability, and the development of regional vegetation. Here we present the first dated terrestrial record from southeast Arabia that provides evidence for increased rainfall and the expansion of vegetation during both glacial and interglacial periods. Findings from extensive alluvial fan deposi… Show more

“…At a smaller scale, more localized alluvial fans have formed around the bases of steepsided jebels and dykes, from which intermittent streams flowed during wet phases (e.g. Parton et al, 2015b;Jennings et al, 2015b). It has been suggested that most of the trans-Arabian wadi systems were incised in their current configurations by the early Quaternary, based on relationships between basal gravel deposits and dated lava flows (Al-Sayari and Zötl, 1978;Anton, 1984).…”

“…The formation of large lakes suggests at least episodic activation of local fluvial systems. Evidence for this is provided by fluvial and alluvial fan deposits in southern Arabia dated to various humid phases (Blechschmidt et al, 2009;Mclaren et al, 2009;Parton et al, 2010;Rose et al, 2011;Atkinson et al, 2013;Parton et al, 2015a) and by incised relict drainage networks overlying Pliocene and Quaternary deposits across the peninsula (see Holm, 1960;Anton, 1984;Edgell, 2006;Blechschmidt et al, 2009).…”

“…However, in light of the unreliability of some early radiocarbon dating highlighted by recent studies (Rosenberg et al, 2011(Rosenberg et al, , 2013, and the identification of Pleistocene terraces in more minor drainage elsewhere re-evaluation of some of these dates may be needed, and further Pleistocene terraces, if identifiable, could provide valuable data. There are now a series of optically stimulated luminescence (OSL) and UraniumeThorium (U/Th) dates indicating that varying levels of fluvial activity have occurred in south-central Arabia during wetter intervals of the midelate Pleistocene (Maizels, 1987;Blechschmidt et al, 2009;Mclaren et al, 2009;Parton et al, 2010Parton et al, , 2013Rose et al, 2011;Sitzia et al, 2012;Atkinson et al, 2013;Parton et al, 2015a), and these provide valuable data on local catchment activity. Information from northern Arabia however, remains limited, and only one of the studies mentioned above is situated in a major trans-Arabian wadi.…”
