چکیده انگلیسی
Glaciohydraulic supercooling has been observed at many modern glaciers and has been shown to generate thick zones of debris-laden basal ice which, when exposed to melting, can produce debris-flow and melt-out till deposits, as well as hummocky terrain. Glaciohydraulic supercooling probably occurred in former continental ice sheets, especially where ice flowed out of deep basins, or up steep slopes. Evidence to support glaciohydraulic supercooling in former ice sheets, however, is limited but may include sedimentary sequences of melt-out till and debris-flow deposits and hummocky terrain along the distal rim of overdeepenings and crests of adverse bed slopes.
