摘要
Coversand deposits, thought to be of Lateglacial age are found in Britain in North Lincolnshire, South-West Lancashire and Central East Anglia. A comprehensive dating study of them, using thermoluminescence (TL) techniques, is currently underway in an attempt to link the British coversand deposits to the European coversand chronology. Initial results from four of the British coversand sites sampled are presented. The 26 TL dates from 14 samples show that in Lincolnshire aeolian deposition took place from 12.5 ka to 11 ka. Cessation of the initial sand deposition was synchronous with this in Lancashire, but sand deposition occurred significantly earlier in East Anglia. The upper layers of aeolian sand in Lancashire are much younger and are attributed to Holocene reworking. On the basis of these dates, Lincolnshire and Lancashire coversand deposition occurred at a similar time to the Younger Coversand II, whilst East Anglian coversand deposition coincided with the Younger Coversand I phase in the European coversand chronology.
