A study of global sand seas

TL;DR: In this article, the authors presented a study on human impact in the Australian semi-arid and arid zone and the sources and types of dune sands are examined, from the earliest evidence of aeolian activity.

TL;DR: A new map based on interpretation of satellite imagery reveals both the complexity of Australia'sdunefieldsandtheirrelationshipswithtopography, climate and vegetation structure.

TL;DR: Palaeowind directions of the early Permian Upper Rotliegendes were predicted from the orientations of dune bedding as mentioned in this paper, which is seen in both outcrop and core and derived from the continuous dip-meter logs of many North Sea wells by plotting the poles to the bedding attitudes on polar nets.

TL;DR: In this article, three types of sand dunes exist in the Taklimakan Desert, namely compound/complex crescent dunes and crescent chains, compound dome dunes, and compound linear dunes.

TL;DR: In this paper, a bar on the Brazos River near Calvert, Texas, has been analyzed in order to determine the geologic meaning of certain grain size parameters and to study the behavior of the size fractions with transport.

TL;DR: In this article, a detailed mapping of the sedimentary geology of Saudi Arabia by the Arabian-American Oil Co. (Aramco) began in 1933, and by 1959, exploration parties of one type or another had surveyed more than 1.3 million square kilometers (500,000 square miles).

TL;DR: In this article, the third moment (skewness) of a normal curve is used to distinguish between dune, beach, and river sand, and the difference between the two types of sand types can be numerically stated by computing the third moments of the distribution curve.
