Luminescence dating laboratory

One room is dedicated to chemical, and another to the mechanical, sample preparation.

The latter houses a manual hydraulic press (Wassermann WW33), a water cooled diamond rock saw (Isomet 1000) and a dry/wet sieving machine (Fritsch Analysette 3).

It was purpose built and comprises rooms for sample preparation and measurement.

Thank you for visting the Utah State University Luminescence Laboratory homepage! We currently have two RISO TL/OSL Readers and one with a single-grain attachment.

As the OSL of a sediment is quickly lost when exposed to sunlight (tens of seconds) many sediments are bleached (lack an OSL signal) when deposited and buried.

After deposition these sediments accumulate luminescence which can be measured allowing the age of burial to be determined.

There is now convincing evidence that many glacial, fluvial, aeolian, and even shallow marine sediments can be dated by OSL techniques.

This research involves the collection of sediment samples in locations as diverse as Arctic Canada, BC's central coast, Australia, and Patagonia.

These samples are then dated, and the age information is used to help understand the nature of long term environmental change.

The Luminescence Dating Laboratory exists since 2003 and is a key research facility of the ‘Environmental Change’ research group.
