Morphometric features of pebbles in a polar environment (Northern Victoria Land, Antarctica)

The flatness and dissymmetry index values are the best "markers' for the type of reworking in the polar environment that has produced the current shape of clasts. The shape is determined for the most part by the lithological response to chemical and physical alterations in the cold-dry polar climate. Moreover, the results of morphometric analyses suggest that in raised beaches there might have been a transport of clasts over short distances from the older beaches to the more recent ones. -from Authors
