Abstract
Spatial and temporal variations in the development of periglacial wedge structures in south-central Ulster. Northern Ireland can be related to climatic change during the earlier part of the late Glacial period. Ice wedges formed in the early stages of deglaciation (c.18,000 — 14,000 yrs B.P.) when cold and relatively humid periglacial conditions prevailed. Sand wedges formed during the later stages of deglaciation (c. 14,000 — 13,500 yrs B.P.?) and suggest a change to colder (?) and relatively drier climatic conditions.Keywords
