| Abstract | The role of ground ice as an initiator of landforms in permafrost regions implies also the formation of landforms which result from the melting of ground ice. Many landforms in permafrost regions owe their origin to the build-up of ice in the ground. Several types of prominent features are formed by the aggradation of permafrost and the accompanying formation of large masses of ground ice, many metres in size. Such landforms include pingos, palsas and peat plateaux, ice wedge polygons and rock glaciers. A second group of landforms associated with the degradation of permafrost and melting of ground ice includes thermokarst depressions and hollows, thaw lakes, thaw slumps, cemetery mounds and beaded streams. The Mackay classification of ground ice has systematized to a considerable degree the relationship between these landforms and forms of ground ice in permafrost regions. |
