Solifluction is a collective name for gradual processes in which a mass moves down a slope ("mass wasting") related to freeze-thaw activity. This is the standard modern meaning of solifluction, which differs from the original meaning given to it by Johan Gunnar Andersson in 1906. In slow periglacial solifluction there are not clear gliding planes, and therefore skinflows and active layer detachments are not included in the concept.

  • Gelifluction
  • Plug-like flow

Slow solifluction acts much slower than some geochemical fluxes or than other erosion processes. In contrast, solifluction sheet sediments move more or less uniformly downslope, thus being a less selective form of erosion than solifluction lobes.

Extraterrestrial solifluction

It has been suggested that solifluction might be active on Mars, even relatively recently (within the last few million years), as observed Martian lobates bear many similarities with solifluction lobes known from Svalbard.
