| Abstract: | There exposures in an outer end moraine ridge at Autre Okstindbredal, north Norway, are described and interpreted. The presence of perennially frozen ground is attributed to the present or very recent climate of the area and suggest the occurence of true sporadic permafrost. Several buried soil horizons including podzols are recognised within the moraine ridge sections. These are considered to be derived. It is thought that their occurance as imbricate stress is best explained by a basal freeze-in mechanism associated with marginal thrusting when the local glacier possessed a sub-polar thermal régime. This freeze-in phase is of late Neoglacial age but not necessarily associated with the widespread eighteenth century advance in Scandinavia. The soils in part date from the postglacial climatic optimum. |
