The aim of this study is to characterise quartzite landforms on different scales in cold environments, focusing mainly on slopes, and using mountains in Northern Ireland, Scotland and Norway as field of study. Theses fields range in latitude from the 55th to the 62nd parallel, in altitude from 500 m to 2 300 m, and are situated near the Atlantic seaboard.

The approach is based on a double comparison : firstly, between rocks : specifying the position of quartzite in scales of resistance according to different periods, thus considering the structural parameters secondly, between mountain environments, defining the place of quartzitic landforms according to environments, present or past, and determining the rate of evolution, therefore considering morphogenetic and paleogeographical variables, such as zonation and glacierization.

Quartzite can be distinguished by dominant mountains which date from Pre-Quaternary times, during which they were the more resistant of rocks. They can be recognised also by the considerable frequency of scree and blockfields this is the result of their susceptibility to the glacial and periglacial processes, which are consequence of their extreme properties : siliceous composition, recrystallization, hardness, brittleness, splitting, low porosity, high resistance to chemical weathering.
