Description: This short course is designed for researchers, professionals, and
students interested in applying luminescence in their research. We will review the scientific basis for
luminescence dating, outline sample collection, talk about “dose rates,” describe a broad range of
suitable applications, and have practical demonstration during a field trip (if possible). This course
will feature luminescence researchers and laboratory directors from Utah State University, the U.S.
Geological Survey, Kansas State University, and from our newest lab in the U.S., University of Texas at
Arlington. Topics of discussion will include hands-on methods for sample collection and applications of
luminescence dating to geological, paleontological, and archaeological settings as well as rock surface
dating features. The course will also provide a primer on how the technique works, the nuts and bolts
behind how the equivalent dose and dose rate are calculated (the two components of the age equation),
and new advances like the portable OSL and rock surface dating. Class will likely be in a place where we
can easily attend a happy hour to discuss our new-found knowledge. If possible, we will show a
demonstration of sample collection in the field, perhaps while filming. Or maybe we will just show the
film as a science comedy.
- History and physics of luminescence dating
- The wonder of the equivalent dose
- The often-forgotten dose rate
- Sampling strategies (current to geology, paleontology, and archeology)
- Future sampling strategies and research directions
There will be short (10–15 minute) breaks between modules. Lunch will be provided. Class will be
limited to 35 participants.
