Form and size characteristics of clasts on stone-banked solifluction lobes, Okstindan, North Norway

Abstract

Subtle yet systematic differences in clast form and size in riser and tread zones on two stone-banked solifluction lobes in Okstindan, North Norway are observed. Clasts located within risers arc larger and tend to be ‘blockier’ (more equidimensional) than those found upon tread surfaces. Such large clasts may act as ‘braking blocks’; retard soil movement in the frontal zone and hence initiate the lobate form.
