Optically Stimulated Luminescence (Osl) Dating Of Perenially Frozen Deposits In North-Central Siberia: Osl Characteristics Of Quartz Grains And Methodological Considerations Regarding Their Suitability For Dating, Lee Arnold, Richard Roberts
Richard G Roberts
Optically stimulated luminescence (OSL) dating of coarse-grained quartz is increasingly being used as the main chronological tool in late Quaternary palaeoenvironmental reconstructions of Siberia. However, relatively little information has been published on the suitability of OSL dating for the various types of perennially frozen sediments found in this region. Here we provide a systematic examination of the quartz luminescence characteristics of 21 perennially frozen samples from the Taimyr Peninsula and adjacent coastal lowlands of north-central Siberia, and discuss their implications for the reliability of single-grain and multi-grain OSL chronologies in such contexts. The results of this study suggest that the …
