Geochemistry Research Laboratory Director: Dr. Nancy J. McMillan

The Department of Geological Sciences houses a number of analytical instruments, all of which are available for use by our undergraduate researchers.  To analyze the atomic structure of crystalline substances, we have an X-ray diffractometer.  The chemical composition of rocks is analyzed by our X-ray fluorescence spectrometer, and micro-analysis (approximately 100 microns diameter) of solids, liquids, and gases is accomplished with our nanosecond and picosecond laser-induced breakdown spectrometers.  The heavy isotopic composition of samples can be determined using our thermal ionization mass spectrometer.  Sample preparation equipment is available to support research on these instruments.  In addition, mineral separation equipment including a jaw crusher, Gemini shaker table, Franz magnetic separator, and heavy liquids, is available for geochronologic or other mineralogic research projects.
