  • geomorphological basis for the interpretation of radiocarbon, cosmogenic isotope and amino acid dates for the timing of deglaciation. The mapping shows that it is possible to make a clear weathering and morphological distinction between last glaciation and older
  • on cosmogenic isotope analysis, C 14 assays, amino acid racemisation and tephrochronology. They unpick the effect of bedrock-derived lignite which has affected many C 14 dates in the past and synthesise new and revised dates that constrain 5 glacier advances
