Assessing the uncertainty on particle size and shape: implications for ESR and OSL dating of quartz and feldspar grains

Duval, M.; Campaña, I.; Guilarte, V.; Miguens, L.; Iglesias, J.; González Sierra, S.


Grain size and shape are two important parameters in Electron Spin Resonance (ESR) and Optically Stimulated Luminescence (OSL) dating of sediment, since they have a direct impact on several correction factors that are used for evaluating the dose rate. These parameters were evaluated by static image analysis for a wide range of quartz and feldspar grain samples. Our results indicate that there are many factors that may influence the final grain size and shape. Overall, grains are not perfect...[Show more]
