Evidence for Neoglacial Solifluction
ABSTRACT. A section excavated through two adjacent turf-banked solifluction lobes has revealed buried soils beneath each solifluction sheet. Five radiocarbon dates are reported from the buried soils and these reveal evidence of soil movement which probably extends over nearly 3,000 years until the p...
