Luminescence dating is a technique used to date Quaternary sediments and for determining when ancient materials such as pottery, ceramics, bricks or tiles were last heated. The technique can be applied to material from about to several hundred thousand years old. It is primarily a research facility for the School and for collaborators in New Zealand. One room serves as preparation laboratory, where all incoming samples are unpacked and chemically treated to purify the sample and extract the desired minerals in the right grain size.

Optically stimulated luminescence
High-wave events result in significant beach erosion and retreat. While understanding of the extent and frequency of extreme beach retreat is critical for conservation of coastal property, modern beach observation is generally too short for the infrequent nature of such events. Here we show a geological assessment of extreme beach retreat in Bengello Beach at Moruya, southeastern Australia, based on the high-resolution quartz optically-stimulated luminescence OSL dating coupled with the Bayesian outlier modeling, and ground-penetrating radar GPR survey.
