Tl dating labs

The School of Geography and the Environment, in association with the RLAHA Luminescence Dating Laboratory, Research Laboratory for Archaeology and the History of Art, houses a state of the art luminescence dating facility: the Oxford Luminescence Dating Laboratory (OLD).Optically Stimulated Luminescence (OSL) dating has emerged within the last 20 years as a key Quaternary absolute dating tool, with a wide range of terrestrial and marine applications.In the space of learning and teaching there have been many successes connected to the faculty, including awards that recognise innovation and creativity in education, and excellence in empowering students in the use of technologies.Today, we received a Laboratory Test Request for composition testing and thermoluminescence (tl) dating of ceramic material.Thermoluminescence dating is used for material where radiocarbon dating cannot be used.This is the case for sediments in the authentication of old ceramic wares.

In addition, it can detect unfired clay and restoration material.quartz, feldspar), which are previously exposed to ionizing radiation, will emit light (luminescence) when they are thermally or optically stimulated.Depending on the type of stimulation source, the phenomenon is termed thermally stimulated luminescence (TL) or optically stimulated luminescence (OSL).If samples are taken from several locations on the piece, TL can also indicate if sections were made from a similar clay.We perform OSL dating research using single aliquot regenerative (SAR) protocol on aeolian, fluvial, colluvial, and lacustrine sand.
