Landforms resulting from the slow downslope flow of saturated unfrozen earth materials (van Everdingen et al. 1998/2005). The term is commonly applied to processes operating in both seasonal frost and permafrost areas.
Mud-debris tongue (not recommended)
Description of Subtypes
Solifluction lobe: an isolated, tongue-shaped feature on Earth up to 25 m wide and >150 m long. It commonly has a steep (15–60°) front (riser) and a relatively smooth upper surface (thread) (van Everdingen et al. 1998/2005) (Fig. 2).
Turf-banked lobes are vegetated lobes. They are non-sorted, displaying arcuate bands of tongue-like shaped fronts (Benedict 1970).
Stone-banked lobes are sorted solifluction lobes (Benedict 1970) ( sorted patterned ground: sorted step). Stone-banked lobes are “lobate mass of rocky debris underlain by relatively stone-free fine-textured, moving soil” (Ridefelt 2004).
