Paraglacial geomorphology of Quaternary volcanic landscapes in the southern Coast Mountains, British Columbia
An important paradigm in geomorphology is paraglacial sedimentation, a phrase first used almost 40 years ago to describe reworking of glacial sediment by mass wasting and streams during and after continental-scale deglaciation. The concept has been extended to include nonglacial landforms and landscapes conditioned by glaciation. In this paper we apply the paraglacial concept to volcanoes in so...
متن کاملCriteria to discriminate between proglacial and paraglacial environments
the original meaning of “areas peripheral to Pleistocene ice sheets and glaciers” (Lozinski 1909) to one which stresses the distinctive processes of freeze-thaw and permafrost formation. In spite of the comment by Worsley (2004) that the term periglacial has no universally accepted definition, there are really only two options that are in common use: a) an environment of frequent freeze-thaw cy...
متن کاملElsevier Editorial System(tm) for Geomorphology Manuscript Draft Title: Geomorphological Consequences of Glacier Advance across a Paraglacial Rock Avalanche Deposit Highlights (for Review) Geomorphological Consequences of Glacier Advance across a Paraglacial Rock Avalanche Deposit
Glacial reworking of paraglacial rock slope material has been inferred from long-deglaciated terrains to be an important component of glacial sediment transfer. We provide the first description from a contemporary glacial environment of the geomorphological consequences of glacier advance (of the Feegletscher Nord, Switzerland) across a paraglacial rock avalanche deposit. The landform-sediment ...
متن کاملThe Arctic in the Twenty-First Century: Changing Biogeochemical Linkages across a Paraglacial Landscape of Greenland
The Kangerlussuaq area of southwest Greenland encompasses diverse ecological, geomorphic, and climate gradients that function over a range of spatial and temporal scales. Ecosystems range from the microbial communities on the ice sheet and moisture-stressed terrestrial vegetation (and their associated herbivores) to freshwater and oligosaline lakes. These ecosystems are linked by a dynamic glac...
متن کاملRates and magnitudes of paraglacial fan formation in the Garhwal Himalaya: implications for landscape evolution
The development of paraglacial fans, studied in the upper Bhagirathi valley, Garhwal Himalaya, northern India, relates to the retreat of the Gangotri Glacier over the last 200 years. These fans demonstrate the speed by which mass movement and fluvial processes may lead to the modification and readjustment of the Himalayan landscapes during deglaciation. The paraglacial fans in this region grew ...
