Luminescence dates for the palaeolithic site of Piekary IIa (Poland): comparison between TL of burnt flints and OSL of a loess-like deposit
Résumé
We report the thermoluminescence age-estimates for burnt flints excavated at the palaeolithic site of Piekary IIa and discuss attempts to date quartz grains extracted from the embedding deposit using the OSL technique with the SAR protocol. The results indicate that this loess-like deposit contains a mixture of grains, well bleached at different periods in the past, and that the study of small aliquots seems to be the only way to discriminate between the different fractions.
