Relationship between the distribution of periglacial landforms and glaciation history, Fildes Peninsula, King George Island, Antarctica

Abstract

Three kinds of profile assemblage features show that periglacial landforms have an internal relationship in genesis. For example, where there is a rich weathering debris, the dominant landforms are talus, black slopes, mass movement features, and mega-grained sorted forms. Where the debris material is silty, fine-grained periglacial forms (for example, gelifluction steps and striated soils) dominate. Where the debris source is limited, talus only appears at the south-east side of periglacial tors and hilltops; the major periglacial forms are striated soils and muddy sorted circles. In general, periglacial landforms show a difference between stoss and leeward slopes.
