The characteristics and significance of deep weathering in the Gaick area, Grampian Highlands, Scotland

Auteurs :
HALL, A. M.

Description :
The Gaick area is a landscape of selective linear glacial erosion. Deep weathering of Moine psammites occurs on preglacial slopes but is absent from glacially-overdeepened valleys. The weathering is of gruss type and its thickness, together with the importance of halloysite in the clay fraction, indicates that the weathering predates the middle Quaternary ice sheet glaciations. The weathering demonstrates very limited erosion of the preglacial slopes and owes its preservation in part to the development of an ice dome over the Gaick area during successive glaciations.
