| Description | Feldspar luminescence dating methods are widely used in Quaternary geology, especially for sediments where quartz OSL dating is not possible.
For equivalent dose estimation, the single-aliquot regenerative (SAR) dose method is normally used. However, recent research has shown that sensitivity correction in feldspar luminescence dating is not as straightforward as in quartz. In this research, you will investigate to what extent light exposure prior to deposition and burial affects apparent luminescence sensitivity during the laboratory measurements. You will gather information from literature, design and carry out experiments in the laboratory of the Netherlands Centre for Luminescence dating, and analyse the data. Based on this you will come gain insight in the validity of presently used dating methods, and you will suggest improvements to methods to increase accuracy of results. |
