Description :
Glacier fluctuations in the Strait of Magellan tell of the climatic changes that affected southern latitudes at 53-55°S during the Last Glacial Maximum (LGM) and Late-glacial/Holocene transition. The AA. present a revised chronology based 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 (A to E)
