Record #112409:

Scanning electron microscopy of quartz grains in supraglacial debris, Adishy glacier, Caucasus mountains, USSR / William C. Mahaney, Rein Vaykmaye, Kai Vares.

Title: Scanning electron microscopy of quartz grains in supraglacial debris, Adishy glacier, Caucasus mountains, USSR / William C. Mahaney, Rein Vaykmaye, Kai Vares.
Author(s): Mahaney, William C.
Vaykmaye, Rein.
Vares, Kai.
Vaikmae, Rein.
Date: 1991.
In: Boreas. (1991.), Vol. 20(4) (1991)
Abstract: Tests assumption that mechanical weathering of source rocks before glacial entrainment may impart some fracture features observed on quartz grains present in glacial deposits. Clasts in transport on surface of glacier originate from cirque headwall by weathering and mass-wasting processes. Results show that mechanical weathering is only likely to produce grains with pronounced fracture faces that lack subparallel and conchoidal fracture features. No fresh glacial-crushing type features were observed.
