The age is obtained by measuring the radiation dose received by the sample since it was last bleached by sunlight, and dividing this estimate by the dose rate from environmental sources of ionising radiation.

The OSL dating laboratory is located in the School of Earth & Environmental Sciences and is headed by Bert Roberts and Zenobia Jacobs.

Turnaround time is dependent on the workload of the lab, so please enquire about the status when submitting samples.

Unfortunately routine sample analysis can take up to five months, but can be longer for unusual materials or if any unexpected problems arise during processing.

The technique can be applied to material from about 100 to several hundred thousand years old.

The Luminescence Dating Facility at Victoria University is the only one of its kind in New Zealand and is led by Prof Rewi Newnham and Ningsheng Wang.

Our luminescence dating service is available for researchers in New Zealand and overseas.

We use optically stimulated luminescence (OSL) to date aeolian, fluvial, lacustrine and shallow water marine sediments, as well as most quartz or feldspar-bearing objects, which have seen sunlight or intense heat during deposition. Two of the Risø instruments used for OSL dating in the UOW laboratory (top left).Grains of quartz or feldspar are mounted on stainless steel or aluminium discs and loaded into the instrument.We therefore welcome projects where low-level radioactivity is expected such as sediments from New Zealand and the Pacific Islands. Standard rate for routine work with priority processing: NZ00 GST per sample. Dating the Kawakawa/Oruanui eruption: comment on optical luminescence dating of a loess section containing a critical tephra marker horizon, SW North Island of New Zealand by R. This price includes all irradiation and luminescence measurements required to obtain the equivalent dose, and high resolution laboratory gamma-spectrometry for dose rate determination. Up to 48 discs can be measured in a single automated sequence.
