eolian
|
Term describing the process of wind erosion, transport, and deposition, and wind-created deposits and structure such as sand dune.
|
|
|
eolian deposits
|
Sedimentary deposits consisting of windblown dust.
|
|
|
sandblasting
|
A physical weathering process in which rock is eroded by the impact of sand grain carried by the wind, frequently leading to ventifact formation of pebble and cobble.
|
|
|
blowout
|
A shallow circular or elliptical depression in sand or dry soil formed by wind erosion.
|
|
|
deflation
|
The removal of clay and dust from dry soil by strong winds.
|
|
|
ventifact
|
A rock that exhibits the effects of sand-blasting or snowblasting on its surfaces, which become fiat with sharp edges in between.
|
|
|
pavement
|
A bare rock urface that provides a protective rock cover over the material beneath it.
|
|
|
desert pavement
|
A residual deposit produced by continued deflation, which removes the fine grain of a soil and leaves a surface covered with closely packed cobble.
|
|
|
dune
|
An elongated mound of sand formed by wind or water.
|
|
|
barchan dune
|
A crescent-shaped sand dune moving across a clean surface with its convex face upwind and its concave slip face downwind.
|
|
|
longitudinal dune
|
A long dune parallel to the direction of the prevailing wind.
|
|
|
yardangs
|
Streamlined hill oriented parallel to the prevailing winds and produced by wind erosion of rock or soft sediment.
|
|
|
seif dune
|
A longitudanal dune having one side rounded, the other side being a steep slip face, and a long sharp edge on the top.
|
|
|
transverse dune
|
A dune that has its axis transverse to the prevailing winds or to a current. The upwind or upcurrent side has a gentle slope, and the downwind side lies at the angle of repose.
|
|
|
parabolic dune
|
A dune in the shape of a parabola. The ends of the dune point in the direction from which the wind was blowing. They are found where thick grass or plants cover the sand. The sand is blown away from an area without plants forming the parabolic dune.
|
|
|
loess
|
A buff-colored, wind-blown deposit of fine silt, which is frequently exposed in bluffs with steep faces. The thickness can range from 6 to 30 m. The loess of the United States and Europe is thought to be the fine materials first transported and deposited by the waters of melting ice sheet during the glacial period. It was later blown considerable distances with in some cases deposition in lakes. The origin of Asiatic loess however is apparently wind-blown dust from central Asian deserts.
