Joanne contrasted the luminescence properties of rock slices placed directly on the carousel, and those placed into a sample cup. The latter had more reproducible luminescence properties.

Joanne’s latest work on reducing variation in OSL rock surface dating profiles is to be published in Quaternary Geochronology! Through numerous experiments, her paper explores the influence of various measurement parameters on scatter observed in OSL-depth profiles measured from rock surfaces exposed in Zermatt, Switzerland. The results of the study highlight the potential impact of thermal lag, and concludes by suggesting that future OSL rock surface dating studies place samples in metal cups, reduce heating rates and increase preheating and holding times to minimise this effect.
