Abstract (Swedish)
Today there is an increased interest in achieving a greater understanding of coastal dynamics as well as ways to determine the provenance of these coastal sediments. Here it is investigated whether the relatively new method of utilising optically stimulated luminescence (OSL), proposed by Gray et al. (2019), is a viable method on Scanian coastal sediments, as the bedrock is highly diverse in comparison to the rest of Scandinavia. Specifically Linear Modulated OSL (LM-OSL), with additionally, a series of sub-recent beach ridges at Sandhammaren present an opportunity to determine if the provenance of Quaternary deposits at the location have changed over time. No distinction in their OSL signature was found based on age, and when comparing to... (More)
Today there is an increased interest in achieving a greater understanding of coastal dynamics as well as ways to determine the provenance of these coastal sediments. Here it is investigated whether the relatively new method of utilising optically stimulated luminescence (OSL), proposed by Gray et al.

Specifically Linear Modulated OSL (LM-OSL), with additionally, a series of sub-recent beach ridges at Sandhammaren present an opportunity to determine if the provenance of Quaternary deposits at the location have changed over time. No distinction in their OSL signature was found based on age, and when comparing to other localities across Scania there were not any particularly identifiable features which could differentiate them from each other or from data of prior studies performed in Scandinavia.
The quartz OSL signals, based upon the photo-ionization cross-section of the samples and indicating the detrapping probability, were characterised by a commonly present fast component, a rarely present medium component, and a most often dominant slow component. The beach ridges at Sandhammaren were dated between 8.5 ± 0.7 ka to 4.3 ± 0.4 ka, indicating that they formed during the Littorina Sea transgression and confirming prior estimates. Similarly to the rest of Scania, quartz from Sandhammaren could not be differentiated regarding to component characteristics based on their luminescence, regardless of age. An alternative approach, using single-grain aliquots during analysis is proposed as a potential solution to the pitfalls of the multi-grain aliquot approach used in the study. (Less)
