Frequency of relic frost-fissure structures and prediction of polygon pattern. A quantitative approach

Auteur :
MAIZELS, J. K.

Description :
The paper aims to demonstrate that the distribution of fissure structures present along linear sections and exposures may be a valuable tool in the prediction of the likely size, density and pattern of associated paleo-polygonal networks and hence in the interpretation of paleoenvironmental conditions. Comparison with Northern Alaska and Arctic Canada suggests that during Younger Dryas times permafrost was probably extensive and mean annual temperatures were up to 16 oC lower in eastern Scotland than at present.
