EVIDENCE FOR A GISP CORRELATIVE 16KA BP STILL STAND DURING THE SCOTTISH LGIT

Cosmogenic surface exposure dating of boulders in the western Cairngorm mountains, Scotland, has ascertained moraine limit ages, formed during deglaciation of both the main Scottish Ice Sheet and the local Cairngorm Ice Cap at around 16ka BP. Geomorphological and sedimentological evidence indicates a still stand period associated with these moraines, which lasted 1ka, and is among several such stages that affected the eastern margins of the Scottish Ice Sheet during the LGIT. Cosmogenic 10Berylium ages are constrained by both 14C and tephrochronology. This key stage in the retreat of British land based ice sheet systems can be directly correlated to climate signals from the Greenland ice cores.
