Bookmark or Share- Loess - WikipediaA loess is a periglacial or aeolian (windborne) sediment, defined as an accumulation of 20% or less of clay with a balance of roughly equal parts sand and silt (with a typical grain size from 20 to 50 micrometers), [3][4] often loosely cemented by calcium carbonate.
- Local regression - WikipediaIts most common methods, initially developed for scatterplot smoothing, are LOESS (locally estimated scatterplot smoothing) and LOWESS (locally weighted scatterplot smoothing), both pronounced / ˈloʊɛs / LOH-ess.
- Loess - National Geographic SocietyThis layer of fine, mineral-rich material is called loess. Loess is mostly created by wind, but can also be formed by glaciers. When glaciers grind rocks to a fine powder, loess can form. Streams carry the powder to the end of the glacier. This sediment becomes loess. Loess ranges in thickness from a few centimeters to more than 91 meters (300 ...
- Loess | Wind-Deposited Sediment & Soil Formation | BritannicaLoess is a sedimentary deposit composed largely of silt-size grains that are loosely cemented by calcium carbonate. It is usually homogeneous and highly porous and is traversed by vertical capillaries that permit the sediment to fracture and form vertical bluffs.
- Loess - Age, Origin, Deposits | BritannicaLoess - Age, Origin, Deposits: For more than a century a number of partly conflicting and partly complementary hypotheses have been put forward to explain the origin of the silt fraction of loess.
