Directed by Professor Mark Bateman. The Sheffield Luminescence Dating Facility specialises in the measurement of quartz and feldspar-rich sands from sedimentary sequences, which can be absolutely dated within a range of 10 to 300,000+ years. Samples from all around the world have been dated, including archaeological sediments from the USA and South Africa, relict cold-climate desert sands from Arctic Canada, dune sands from Zambia, Zimbabwe, The Netherlands and UK and lake sediments from Mexico.
