Eras Epochs. Owen, L. Other important factors that need to be considered when calculating the radiation dose rate are the water content of the sediment and how much sediment is on top of the sample site. We have to be very careful not to expose the sediments to sunlight when we do this! A status review".
Recent advances in OSL dating techniques for feldspar 23 may result in this becoming the preferred mineral for OSL dating of glacial sediments, although feldspars are often more severely affected by partial bleaching than quartz.
Optically stimulated luminescence thermochronometry
Road cut through glacial outwash sediments, Patagonia. During detrapping of these electrons, luminescence is produced. Lee et al. As time goes on, the ionizing radiation field around the material causes the trapped electrons to accumulate Figure 2. If we assume that the radiation dose rate of the sediment has remained constant over time, then if we measure that dose rate, we can calculate the sample age.
