Gelisols are an order in USDA soil taxonomy. They are soils of very cold climates which are defined as containing permafrost within two meters (6 ft 7 in) of the soil surface.

Gelisols are perennially frozen soils of the Arctic and Antarctic regions, but they are also found at extremely high elevations in the lower latitudes. They are fragile, easily eroded soils, and their location near the polar ice caps makes them important indicators of the …

Gelisols are soils that have permafrost near the soil surface and/or have evidence of cryoturbation (frost churning) and/or ice segregation.

Gelisols (from Latin gelare, "to freeze") are soils of very cold climates that contain permafrost within two meters of the surface. These soils are limited geographically to the high-latitude polar regions and localized areas at high mountain elevations.

Gelisols are soils with permafrost within 2 meters of the surface. These soils generally have limited profile development. Most of the soil forming processes in these soils occur near the surface, sometimes resulting in significant accumulation of organic matter.

Gelisols are soils of very cold climates that contain permafrost within 2 meters of the surface. These soils are limited geographically to the high-latitude polar regions and localized areas at high mountain elevations.

Jul 2, 2013 · Gelisols, most notably those with ice-cemented permafrost, have unique morphological properties caused by patterned ground formation, cryoturbation, and cryostructures caused by freeze–thaw cycles.

Jan 1, 2014 · Gelic materials are mineral or organic soil materials that have evidence of cryoturbation (frost churning), ice segregation in the active layer, or the upper part of the permafrost. Low soil temperatures cause soil-forming processes such as decomposition of organic materials to proceed very slowly.

May 8, 2013 · Gelisols are soils affected by permafrost. It was the 12th order added to Soil Taxonomy, the U.S. soil classification system. They are classified as Cryosols in both of the World Reference Base and the Canadian System of Soil Classification, and Cryozem in the Russian soil classification system.
