Mechanical and chemical weathering of periglacial and non-periglacial forms on the eastern Fosheim Peninsula, Ellesmere Island (Northwest Territories)
The purpose of this study is to examine the differences in the mechanical and chemical weathering of different periglacial and non-periglacial forms on the eastern Fosheim Peninsula. Forms studied include: solifluction lobes, non-sorted stripes, polygons, mudboils, wetted sloped, dry ridge and wet m...
