Abstract
An SEM-study of the glossy surfaces occurring on quartzitic glacial be ds from Scotland has shown that they are related to two coating-types. The first one is mainly composed of silica and the second one may be nearly pure TiO2 confirmed by EDS chemical analysis and Raman spectrom etry. The origin of these coatings may be interpreted in terms of stre ss-dependent solution and melting processes intervening during stick-s lip movement of the glacier.
