The late Holocene coastal dunefield at Vejers, Denmark: characteristics, sand budget and depositional dynamics

budget of the dunefield and to discuss dunefield dynamics in relation to characteristics of the wind, sediment supply, sea level and human influence. The Vejers dunefield formed on a prograding shoreline supplied with large quantities of sediment from

Quantitative estimates of the effect of climate change on dust storm activity in Australia during the Last Glacial Maximum

of information on LGM climatic change. Dust storm seasons were lengthened and dust paths were modified. Estimates based upon climate alone, without considering the increased supplies of sediment to dust source areas during the LGM, however, probably underestimate

Geomorphology and sediments of sand ramps in the Mojave Desert

relict features and accumulated in periods of higher sediment supply from fluctuating and/or desiccating paleolakes during the late Pleistocene.

Luminescence dating of sand ramps in the Eastern Mojave Desert

Manix, in the west, to the Colorado River, in the east. The periods of accumulation have been identified on the basis of quartz TL dating, and potassium feldspar TL and IRSL dating. The continuity of sand supply to potential deflation areas is seen
