True and anomalous TL dates from Late Pleistocene loess-palaeosol deposits at the Kolodiiv site (East Carpathian Foreland, Ukraine)

Abstract

Twenty-five samples were selected from the Kolodiiv site (7 profiles) for total-bleach thermoluminescence dating. Only about 50% of the TL ages corresponded well to the age expected on the basis of geological interpretation. The rest of the TL dates are overestimates. The discrepancies between the TL age and the geological age of the deposits probably resulted from the presence of an admixture of poorly bleached material, of local origin, transported over a very short distance.
