This chapter defines and describes the global distribution of sand seas and large dunefields. Factors controlling their distribution and size are discussed, including climate, topography, the distribution of large sand sources, and regional-scale sand transport pathways. The response of sand seas and ...

A Study of the Formation of Sand Dunes and Paleosols in the Würm Glacial Age, North Kyushu The break between a paleosol and overlying dune sand of the succeeding deposits is associated with discontinuous gravel and peat. It would appear that the upper part of the solum of the paleosols had...
There are about 100 km\+2 of aeolian landforms consisting of gobi and sand dunes on the piedmont surface of rock stream slope at west side of Puruogangri icefield in the center of the Qinghai\|Tibet Plateau. This is one of the world s rare proglacial desert deposits and also the first...
200 cal bp, when agricultural activities intensified and Pinus and Eucalyptus were planted to stabilize the sand dunes. Pervasive prehistoric land-use activities since at least the Bronze Age Nuraghi period included the cultivation of Prunus, Olea europaea and Juglans regia after 3,500–3,300 cal ...
