Glacial stages and radiocarbon dates in Scotland

Synopsis New radiocarbon dates and previously published ones related to Scottish glacial events are discussed. Dormer’s conclusion that the Loch Lomond and Menteith end-moraine complexes were produced at the limit of the Zone III Readvance is confirmed. It is suggested that the Perth Readvance maximum occurred between 13 500 and 13 000 years ago, that the Aberdeen-Lammermuir Readvance post-dates a long interstadial, that an ice-movement during which shelly drift was deposited near Berwick pre-dates it, and that during the interstadial the British Isles were largely or entirely free of ice.
