Clay pellets and companion sand often build discrete dunes rather than extensive sheets. Two major dune systems form the principal types of aeolian clay dunes in southern Australia: the clay lunettes of relict lakes, and the Mallee dunefield of the Murray Basin. However, aeolian
Aeolian sedimentation and climate variability during the late ...
Aug 11, 2008 · Using the easily distinguished geochemistry of the local quartz sands, we reconstruct the first terrestrial record of both local and far traveled aeolian sedimentation for the Australian region.
Aeolian processes - Wikipedia
Another example of an aeolian system is the arid interior of Australia. With few topographic barriers to sand movement, an anticlockwise wind system is traced by systems of longitudinal dunes. [ 61 ]
Aeolian sands: Characterization, options of improvement and …
Dec 30, 2014 · The author proposed four ways to tackle the problems caused by wind-blown sand: (1) enhancing its deposition, using ditches, fences or tree belts; (2) enhancing its transport, using streamlining techniques, creating a smooth texture over the land surface, or by erecting panels to deflect the air flow; (3) reducing the supply of sand upwind ...
The Botany Sands of southeast Australia: A Quaternary inland …
May 15, 2022 · We identify aeolian terrains flanking glacial-stage shelves subject to onshore winds. A set of legacy particle-size data confirms that the Quaternary Botany Sands of southeast Australia consist of two elements: inland aeolian sands and organic-rich swamp sediments.
Late Neoproterozoic periglacial aeolian sand sheet, Stuart …
May 9, 2007 · The late Neoproterozoic (ca 600 Ma) Whyalla Sandstone covers 25 000 km 2 in outcrop and subcrop on the Stuart Shelf, South Australia, and is coeval with the Marinoan glaciogenic succession in the adjacent Adelaide Fold Belt.
The continental dunefield of Australia - Vignette Collection
Feb 28, 2024 · Dunefields cover a large portion of the Australian continent in areas with favourable topography, climate and sand supply. The main areas of dunes lie in a diagonal band across the continent from the Mallee dunefield in the southeast to the Great Sandy Desert in the northwest (Fig. 1).
Review and direct evidence of transgressive aeolian sand sheet …
May 13, 2022 · The formation and evolution of a new transgressive aeolian sand sheet phase triggered by large-scale shoreline erosion in South Australia is presented. According to the results from historical and satellite images, local shoreline erosion began in the late 1970s and has continued at highly variable rates.
Aeolian landscapes in central Australia: gypsiferous and quartz …
The gypsifierous dunes consist of a surficial gypcrete overlying an aeolian sediment sequence below, a mixture of gypsum sand and quartz sand. No clay pellets have been found in the dune sequence, in significant contrast to the gypsiferous clay dunes in other parts of Australia.
Investigation on the shear strength of compacted aeolian sand …
6 days ago · Aeolian sand widespread in the arid and semi-arid regions has been taken use as the cost-optimal subgrade filling materials. Under the drought climate, the performance of the compacted aeolian sand subgrade is largely dependent on its unsaturated strength. In this work, the shear strength with respect to the matric suction of unsaturated aeolian sand was investigated. A series of triaxial ...
