The morphology is related to the structures of Mesozoic substratum modified by denudation, glacial erosion and glaciotectonics (Maksiak et al.
Considerable discussion regarded the evaluation of glacial erosion in a region covered by polythermal ice, and the subsequent sediment flux to the ocean (an extension of the international "source-to-sink" research but with an emphasis on the role of glacial dynamics).
Such a chronology infers that the weathering pits, seen today, only are remnants of larger pits subdued by glacial erosion.
The Cuillins formed 60 million years ago and the distinctive jagged outline of the main ridge is the result of glacial erosion.
Formed 60 million years ago, the distinctive jagged outline of the main ridge is the result of post-Ice Age glacial erosion.
Valleys are usually very wide and shallower, with more gentle slopes, the result of glacial erosion or meandering rivers.
However, by studying sediments recovered from a deep channel off the southwestern coast of Norway, where mud accumulated at rates some 100- to 500-times greater than the ocean average (due to glacial erosion on the adjacent continent), we have recently been able to read the record of the shifting conveyor.
The deposit is interpreted to have been formed by the concentration of uranium minerals leached from nearby highly radioactive intrusive rocks and deposited in an old riverbed channel, which was preserved from glacial erosion by a cover of younger volcanic rocks.
The festival explores raw materials from their origins inside the earth; their extraction, and their transformation through art, industry and manufacturing; taking in Neolithic rock art, glacial erosion, remnants of the coal mining and minerals industries, and today's concerns over exploitation of resources around the world.
Most of the depressions probably resulted from increased glacial erosion and formed at the same time with the drumlins, as they are also elongated in the direction of ice movement.
The model then suggested that it was glacial erosion that was keeping the mountains' height in check.
