Welton-le-Wold, Lincolnshire: Optically stimulated luminescence (OSL) dating of Pleistocene glacial tills and interglacial gravels

Author(s): John Aram, Joanne Hambly, James Rackham, Jean-Luc Schwenninger, Jim Williams

A series of ten samples were collected for optically stimulated luminescence (OSL) dating from exposed faces and boreholes at a disused quarry near the village of Welton-le-Wold in Lincolnshire. The reinstated former sand and gravel pit is a designated geological Site of Special Scientific Interest (SSSI) due to the presence of an extensive sequence of glacial tills overlying thick deposits of silts, sand, and gravel containing Palaeolithic artefacts and faunal remains. The site is recognized as being of national interest to our understanding of Middle/Lower Palaeolithic human occupation of the region and of critical importance for establishing the glacial history of Eastern England. Much controversy has surrounded the dating of this Pleistocene sequence, and the recent re-exposure of key quarry faces provided an opportunity to reassess the stratigraphic record and apply novel sampling methods and dating techniques.
