Most of the dust carried by dust storms is in the form of silt-size particles. Deposits of this windblown silt are known as loess. The thickest known deposit of loess, up to 350 meters (1,150 ft), is on the Loess Plateau in China. [33] This very same Asian dust is blown for thousands of miles, forming deep beds in places as far away as Hawaii. [34]
Angular rocks and sand grains that have been left behind during the gradual removal of finer particles by aeolian processes. Lag deposits can also form due to removal of finer particles by water. Yardangs: A protruding rock that results from a streamlined carving from consolidated material by wind abrasion by dust and sand, and deflation.
Eolianite or aeolianite is any rock formed by the lithification of sediment deposited by aeolian processes; that is, the wind. In common use, however, the term refers specifically to the most common form of eolianite: coastal limestone consisting of carbonate sediment of shallow marine biogenic origin, formed into coastal dunes by the wind, and ...
Aeolian or eolian (depending on the parsing of æ) is the term for sediment transport by wind. This process results in the formation of ripples and sand dunes . Typically, the size of the transported sediment is fine sand (<1 mm) and smaller, because air is a fluid with low density and viscosity , and can therefore not exert very much shear on ...
Changes in hydrological cycle and vegetative cover impact these patterns and have a large impact on global dust production, with dust deposition estimates ranging between 1000 and 2000 Tg/year. [2] Aeolian dust is a critical part of the iron cycle by transporting iron particulates from the Earth's land via the atmosphere to the ocean. [23]
Rain dust, also known as sediment precipitation – Form of precipitation containing visible dust; Regolith – A layer of loose, heterogeneous superficial deposits covering solid rock; Sand – Granular material composed of finely divided rock and mineral particles; Sedimentology – Study of natural sediments and their formation processes

A loess (US: / ˈ l ɛ s, ˈ l ʌ s, ˈ l oʊ. ə s /, UK: / ˈ l oʊ. ə s, ˈ l ɜː s /; from German: Löss) is a clastic, predominantly silt-sized sediment that is formed by the accumulation of wind-blown dust. [1] Ten percent of Earth's land area is covered by loesses or similar deposits. [2]
