Grain size characteristics of linear dunes in central australia

, : Grain size characteristics of linear dunes in central australia. Journal of Arid Environments 16(1): 23-28

Sands from the crests of the central Australian linear dunes are twice as well sorted as those from the swales, and sorting improves uniformly from swale to dune crest. Mean grain size, skewness, and kurtosis, however, do not show significant topographic variation. The proportion of fines, i.e. particles < 0.063 mm in diameter, decreases uniformly from around 4% in the swales, and 3% on the lower dune flanks, to < 0.5% on the dune crests. Topographic variation in the proportion of fines does not appear to have been described previously for linear dunes. Regional variation in grain-size characteristics within the linear dunefields of central Australia is slight. The sands of the central Australian linear dunefields are closely comparable with those of linear dunes in the Kalahari, save that the swale sands in the Kalahari are generally finer than those in central Australia.
