REGIONAL CLIMATIC VERSUS LOCAL CONTROLS ON PERIGLACIAL SLOPE DEPOSITION : A CASE STUDY FROM WEST CORNWALL
@inproceedings{J2005REGIONALCV, title={REGIONAL CLIMATIC VERSUS LOCAL CONTROLS ON PERIGLACIAL SLOPE DEPOSITION : A CASE STUDY FROM WEST CORNWALL}, author={J. and Knight}, year={2005} }
In contrast with much of the British Isles, south-west England was likely not glaciated during the Quaternary era (last 1.8 Ma) (Stephens, 1970; Bowen et al., 1986; Scourse, 1996; Cullingford, 1998; Clark et al., 2004). Although, therefore, unaffected directly by the sediment generation and erosion processes associated with glacial action, this also meant that it was unaffected by the presence of regional stratigraphic unconformities, formed during ice advance, which have the unfortunate effect…
