OSL dating can be used to determine the time since naturally occurring minerals, such as quartz and feldspar, were last exposed to light within the last few hundreds of thousands of years. It is one of the main methods used to establish the timing of key events in archaeology and human evolution, landscape and climate change, and palaeobiology.
The key importance of luminescence dating within Scottish Archaeology lies in the nature of the events represented by the various dating materials. In this respect, and in extending the range of dating materials and questions available, there have significant developments in .
Optically Stimulated Luminescence (OSL) as well as Thermoluminescence (TL) can be applied to heated objects made from clay. Sediment dating When sediments cover an archaeological site they are exposed to light and the mineral grains are bleached.
