Catena8, p. The OSL (optically stimulated luminescence) dating method exploits dosimetric properties of grains of minerals naturally occurring in sediments and man-made materials. In archaeology the OSL method is used to date pottery and other heated materials (e.g., bricks, stones, earth) or. However, the discrepancy between certain dates and some hypotheses based on the geomorphologic data related to Middle Pleistocene deposits shows the necessity to carry on with these kind of studies in order to resolve the contradiction of the currently available results.
