Reciet periglacial structures. Occurrences, age and development in different matrices on a coastal plain of southwestern Sweden

Auteur :
SVENSSON, H.

Description :
Ice-wedge formation and wedge characteristics in a broad range of matrices (glaciofluvium, glaciomarine sediments, till and eolian deposits) are analyzed. The distribution of ice wedges according to the upheaval of the area in Late Weichselian is considered and the chronology of polygon formation discussed by means of shore-line spectra and radiocarbon dating. The past arctic environment (the Dryas cold phases) is elucidated by comparison with present periglacial processes in areas of West Spitsbergen with an analogous geographical character (isostatically raised coastal plain with loose deposits).
