The significance of rock structure, lithology and pre-glacial deep weathering for the shape of intermediate-scale glacial erosional landforms

Authors(s) and Affiliation(s)



To explore the effects of multiple glacial erosion on the rock surfaces, an island with 2 different lithologies and with striae from different directions was selected for a detailed study, focusing on the shape of roches moutonnées. Air-photo interpretation of bedrock lineaments and roches moutonnées combined with detailed field maping and striae measurements are used to interpret the structural and lithological control on the resulting shape. The study reveals a significant difference in shape between roches moutonnées in augen-granite and orthogneiss and that coincidence between ice flow direction and pre-glacially etched structures is most likely to determine the effects of glacial erosion
