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. The word "Gelisol" comes from the Latin gelare meaning "to freeze", a reference to the process of cryoturbation that occurs from the alternating thawing and freezing ...
USDA soil taxonomy (ST) developed by the United States Department of Agriculture and the National Cooperative Soil Survey provides an elaborate classification of soil types according to several parameters (most commonly their properties) and in several levels: Order, Suborder, Great Group, Subgroup, Family, and Series.
In the US, Gelisols occur only in parts of Alaska; they are characterized by having permafrost within 100 cm of the surface. Histosols are organic soils lacking permafrost within 100 cm of the surface; they are characteristically formed on wet sites, e.g. bogs, some fens and some muskeg areas. Some Histosols have been drained, especially to ...
In the World Reference Base for Soil Resources (WRB), [5] soils with redox processes due to ascending groundwater belong to the Reference Soil Group Gleysols. Soils with redox processes due to stagnant water are Stagnosols and Planosols.
Thus, Histosols are very important ecologically because they, and Gelisols, store large quantities of organic carbon. If accumulation continues for a long enough period, coal forms. Most Histosols occur in Canada, Scandinavia, the West Siberian Plain, Sumatra, Borneo and New Guinea.

Unweatherable parent materials – sand, iron oxide, aluminium oxide, kaolinite clay. Erosion – common on shoulder slopes; other kinds also important.; Deposition – continuous, repeated deposition of new parent materials by flood as diluvium, aeolian processes which means by wind, slope processes as colluvium, mudflows, other means.
If the tephras are more basic or the climate is dry, amorphous colloidal materials, including allophane and imogolite develop, and the Andosols are given the Silandic qualifier. [5] In both cases, they contain many ferrihydrite and have a bulk density ≤ 0.9 kg/dm 3 . [ 6 ]
