On the glacial relief classification

Abstract

Taking into consideration mechanisms of the glacial relief formation (as they are known at present) the classification of such a relief based on its genesis distinguishes two principal categories: glacial destructional relief and glacial constructional one. The former includes sub-categories of glacio-erosional and glacio-extrusive relief; to the latter belong sub-categories of glacio-erosional, glacio-protrusive, glaciodynamic texturogenic, and glaciotectonic and glaciokarst relief. Along with the listed categories many element-landforms and form assemblages of complex (mixed) origin are widespread in the areas glaciated at present or in the past; such are marginal glacial formations of constructional-glaciotectonic type.
