Periglaciation

[6] According to Alfred Jahn, his introduction of his work at the 1910 International Geological Congress held in Stockholm caused significant discussion.

[8] The 'zonal' concept of physical geography has its roots in the work of the German geomorphologist Carl Troll within the general idea of climatic geomorphology.

[9][10] In 1935, Melik discovered that frost weathering had been a very successful geomorphic process in non-glaciated regions of the Slovenian Alps throughout the Pleistocene.

The word "periglacial" was not well-known at the time so he merely emphasized enhanced transit of scree down the slopes in relation to mass movement processes.

In 1963, Melik introduced the term "periglacial" in the second version of the general section of his Slovenia book, where he also provided a more thorough description of the dominant geomorphic processes on the slopes.

Hugh M. French's classification recognizes six climate types existing in the present:[12] Periglaciation results in a variety of ground conditions but especially those involving irregular, mixed deposits created by ice wedges, solifluction, gelifluction, frost creep and rockfalls.
