Preservation of relict weathering remnants, as a result of ineffective glacial erosion
during the Quaternary glaciations, has occurred in, for example, Fennoscandia (Kaitanen 1969; Sodermann et al.
Here, intense glacial erosion
has not only carved the surface of the mountain range, but has also elicited a structural response from deep within the mountain.
In August he attended the AAAS meeting in Cleveland, Ohio and delivered papers on the inadequacy of glacial erosion
, which were disputed by N.
Sheet structures in granites: Its origin and use as a measure of glacial erosion
in New England.
Based on the above reports, general conclusions can only be drawn: (1) bedrock topography has formed as a result of long-lasting pre-Quaternary continental denudation, (2) deep incisions result from the erosion of ancient rivers, and (3) small undulations in bedrock topography originate mainly from glacial erosion
Cotton (1942) referred to glaciation as a 'climatic accident' and Pauly (1957) referred to 'world-wide abnormal climates" Such events were regarded as being superimposed on static continents where deep glacial erosion
and deposition of coarse bouldery sediments such as tills simply interrupted an otherwise orderly Davisian cycle of landscape and sediment evolution from youth to maturity.
2, 8, 9), which implies that the till matrix is not composed of material derived only from glacial erosion
of underlying bedrock.
Unfortunately, glacial erosion
has removed interglacial or interstadial deposits from the major part of the drumlin field.
This suggests that glacial erosion
of these pipes has been minimal and that most of the pipes' original dimensions have been preserved.
Different reasons have been set forth for the formation of these palaeoincisions: (1) preglacial or interglacial river erosion, (2) glacial erosion
of the Pleistocene glaciers, (3) glacial and glaciofluvial erosion during repeated advances and retreats of the Pleistocene glaciers.
