Formation of sorted patterned-grounds - a literature review

Auteur :
DĄBSKI, M.

Description :
The article presents and compares current views on the development of sorted patterned-grounds in the periglacial zone. The theories can be divided into 8 groups, which assume : 1) convection and/or circulation of the ground en masse ; 2) circulation of only fine particles of the ground ; 3) convection of pore water ; 4) heave-settlement pulsation and lateral expansion on the fine domains ; 5) cracking of the ground followed by heave-settlement pulsation and lateral expansion of the centres of polygons ; 6) cracking and filling of the fissures by allochthonous coarse material ; 7) gravitational displacement of coarse material due to melting of underlying glacier ice ; and 8) solifluction, linear erosion and/or helical flow. - (BJ)
