Its lower limit lies at about 2500 m in the north and 3800 m in the south. Solifluction processes produce a variety of landforms ranging from large (sheets, streams, terraces) to small (stripes, turf-banked steps) forms. Movement rates vary from 1–2 mm/a to 300 mm/a. Three mechanisms of movement are distinguished according to the predominance of frost creep, flow or massive sliding. Present-day, Holocene and Pleistocene solifluction features are recognized.

Sa limite inférieure se trouve à environ 2500 m dans le nord et 3800 m dans le sud. La solifluxion produit des grandes forme (nappes, coulées, terrasses) et des formes plus petites (stries, banquettes contrôlées par la végétation). Les vitesses des mouvements varient de 1 à 2 mm jusqu'à 300 m par an. Trois mécanismes responsables des mouvements sont distingués à savoir le frost creep, le fluage et les glissements de masse. Des formes dues à la solifluxion actuelle, holocène et pleistocène ont été reconnues. Copyright © 1999 John Wiley & Sons, Ltd. REFERENCES Egginton, P. A. and French, H. M. (1985).
