Brit.

/ˈdʒɛlᵻsɒl/, U.S.

/ˈdʒɛləˌsɔl/,

/ˈdʒɛləˌsɑl/

Origin: A borrowing from German. Etymon: German Gelisol.

Etymology: In sense 1 < German Gelisol (C. Troll 1948, in Erdkunde 2 6/2), shortened < Pergelisol pergelisol n. In sense 2 directly < classical Latin gelāre to freeze (see geal v.) + -i- connective + -sol comb. form. Compare earlier pergelisol n.

Soil Science.

1. Soil, or a soil, which is affected by regular or permanent freezing. Cf. pergelisol n. rare.

ΚΠ

1949 Jrnl. Geol. (Chicago) 57 621/1 Troll..states that active annual gelisol is present in the Scandinavian mountains, active diurnal gelisol in many mountains of low and middle latitudes.

1974 Meteorol. & Geoastrophysical Abstr. 25 i. 160 There are indices for the fact that the sandy-silty cover was superimposed by a younger gelisol.

2. Usually with capital initial. A soil of an order comprising soils which rest on or contain permafrost.

Agric.) 33/1 A new order, the Gelisols, should be established to recognize the unique morphologies of soils and soil-forming processes at the high latitudes and altitudes.

1998 Geoderma 81 283 Gelisols have one or more of the following: (1) permafrost within 100 cm of the soil surface; or (2) gelic materials within 100 cm of the soil surface and permafrost within 200 cm of the soil surface.

2006 C.-L. Ping et al. in F. S. Chapin et al. Alaska's Changing Boreal Forest iii. 32 Soils on north-facing slopes and bottomlands have permafrost tables within 1 m and are thus classified in the Gelisol order (permafrost-affected soils).
