Finite Mixture Model News Today

One of the biggest challenges in optically stimulated luminescence (OSL) dating is to deal with sediments that are affected by post-depositional mixing. Equivalent dose (De) distributions of such samples are commonly analysed using the finite mixture model (FMM), which can statistically identify dose components of grains derived from sedimentary layers with different ages. The FMM has been increasingly applied in OSL dating of sediments from key geological and archaeological sites that are criti...

Arid Australia’s landscape and environmental history is unique on a global scale, with the Lake Eyre Basin (LEB) covering one seventh of the Australian continent. The extensive river systems within the LEB are also unique in their morphology. Of these Cooper Creek and the Diamantina River, the two main feeder rivers to Kati-Thanda- Lake Eyre are investigated within this thesis using Optically Stimulated Luminescence (OSL), sedimentological analyses to understand the chrono-stratigraphy and sed...
