Record #119700:

The nature and geomorphological relationships of earth hummocks (thufa) in Iceland / John Gerrard.

Title: The nature and geomorphological relationships of earth hummocks (thufa) in Iceland / John Gerrard.
Author(s): Gerrard, John.
Date: 1992.
Abstract: Thufa are classified as special non-sorted forms of patterned ground, and are result of ice action in soil, although precise mode of formation is unclear. Conclusion is that thufa form within limits determined by soil grain size, soil depth, local climate, depth of soil water table and geomorphological environment. They should be seen as part of continuum of processes acting on vegetated Icelandic slopes and not treated in isolation.
