Aeolian processes - Wikipedia
Aeolian processes, also spelled eolian, [1] pertain to wind activity in the study of geology and weather and specifically to the wind's ability to shape the surface of the Earth (or other planets).

Wind-deposited sand bodies occur as sand sheets, ripples, and dunes. Sand sheets are flat, gently undulating sandy plots of sand surfaced by grains that may be too large for saltation. They form approximately 40 percent of eolian depositional surfaces.

Aeolian (Dunes) Landforms - Geology (U.S. National Park Service)
Dec 1, 2022 · Sand dunes (both active and stabilized by vegetation) can be found along beaches, and in arid or semi-arid regions. Dunes are mounds of loose sand created by wind and are the most well known aeolian features.
Aeolian landform - Wikipedia
Aeolian landforms, or Eolian landforms, are produced by either the erosive or depositive action of wind. These features may be built up from sand or snow, [1] or eroded into rock, snow, or ice.
Eolian sediments | U.S. Geological Survey - USGS.gov
Dec 2, 2020 · Eolian sediments consist of windblown sand, loess, and long-range-transported (LRT) dust, in order of decreasing particle size. Eolian sand forms some of the most dramatic landscapes in the world, particularly when these sediments are deposited as dunes in sand seas.
20.1: Eolian Processes - Geosciences LibreTexts
May 24, 2024 · Eolian processes are most effective where surface material is fine, dry and loose. Vegetation imposes a frictional force on the wind to reduce its effectiveness. Thus, an environment devoid of vegetation is best. These conditions are met in deserts found on every continent of the world.
Eolian sand bodies of the world | U.S. Geological Survey - USGS.gov
This chapter examines the eolian sand bodies of the world. Analyses regarding grain size and sorting distribution at Great Sand Dunes indicate that the higher dunes contain much more fine-grained sand and much less medium-grained sand than do the lower dunes, and, in addition, they are definitely better sorted.
Surficial eolian sand, previously classified as the Parkland Sand (Wil-liam and Frye 1970, Lineback 1979), consists of geomorphologically distinct dune sand and relatively flat-lying sand sheets in inter-dune areas. Eolian sand is very well sorted, medium to …
Eolian Sediments and Processes - SpringerLink
Eolian sediments consist of wind-blown sand, silt (loess) and fine-grained, long-range-transported (LRT or aerosolic) dust. For paleoclimatologists, eolian sand deposits may indicate periods of relative dryness in a region when vegetation cover is minimal.
