FIELD NOTES Raman Spectrometer
Fall 2019
The Department of Geosciences continues to grow its analytical capabilities with the addition of a state-of-the-art Raman spectrometer. Our new (pricey) instrument was secured by Dr. Alexis Ault and is managed by Alexis, Dennis Newell, and Kelly Bradbury. It is housed with other researchgrade microscopes in the new Geoscience Microscopy Laboratory -- renovated and repurposed from a windowless, second-floor classroom many of us taught and learned in. The new Raman will be up and running this fall, as we await the arrival of a special anti-vibration table to ensure high quality data.

The Raman spectrometer (a Labram HR Evolution manufactured by Horiba Instruments) analyzes the chemistry of rocks and fluids down to the micron scale. Different wavelength lasers can excite molecules in the material, producing electromagnetic radiation diagnostic of composition (mineralogy) and structural integrity (amorphous vs. crystalline). Our new instrument also includes extra hardware and capabilities for fluid inclusions, so that we can analyze fluids that are trapped in rocks. These methods are rapidly becoming important tools to address questions in petrology, material science, and geochronology – and it especially adds to the capabilities of our faults-andearthquakes research group. Numerous faculty and student researchers here and elsewhere will integrate this exciting new technique in their research!
At Goosenecks State Park, Dr. Katie Potter uses her trusty travel-sized whiteboard to teach her Intro Geology class and several unsuspecting tourists. At the overlook, almost 300 million years of geologic processes are on full display. Teaching geology at the USU Blanding campus offers great opportunities to share the iconic geology of the Colorado Plateau with students.
