Optical luminescence dating laboratory
We recommend using steel cylinders to collect sediment samples as they are easy to use and transport and protect samples from ambient light. Sedimentology of a debris-rich, perhumid valley glacier margin in the Rakaia Valley, South Island, New Zealand.
The steel cylinders used by our laboratory have a diameter of 60mm and are 100 mm in length, with a sharp edge on one side.
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.
Our luminescence dating service is available for researchers in New Zealand and overseas.
We will also advise you about sampling and help with the interpretation of results.
Turnaround time is dependent on the workload of the lab, so please enquire about the status when submitting samples.
Identify a suitable sediment outcrop – ideally a sandy/silty consistency2.
Cut back the surface of the outcrop by about 20 cm to expose fresh material3. Slip Rate on the Wellington Fault, New Zealand, during the Late Quaternary: Evidence for Variable Slip during the Holocene.
