Ice marginal ramps : an indicator of semi-arid piedmont glaciations

Auteur :
KUHLE, M.

Description :
Under semi-arid environmental conditions, the syngenetic contribution of two agents of transport (glacial, glaciofluvial) in forming one accumulation complex produces stratigraphic and phenotypical features that are rare in the glacial morphology of the temperate/humid zones. For this reason, they are often misinterpreted. Being indicator of ice margins, ice marginal ramps permit the accurate reconstruction of extensive piedmont glaciations in the semi-arid highlands of subtropical latitudes. Because of their high variation values these play a key part in the global energy balance and thus, in the origin and the evolution of ice ages.
