Caledonia Glacigenic Group
The Caledonia Glacigenic Group is a Quaternary lithostratigraphic group (a sequence of rock strata or other definable geological units) present across the whole of Great Britain to the north and west of the furthest limit of Devensian glaciation i.e. throughout Scotland, Wales and northern England. It consists of a wide range of deposits deriving from the Devensian glaciation of glacial, glaciofluvial, glaciolacustrine and glaciomarine origin. It was previously known as the South Britain Glacigenic Group. Its upper boundary is the present day ground surface or an unconformable contact with the Britannia Catchments Group or the British Coastal Deposits Group.
