Welcome
The Boise State University Isotope Geology Laboratory (IGL) is a state-of-the-art facility for the analysis of radiogenic isotopes in Earth materials, with a focus on high-precision geochronology (U-Pb zircon) and tracer isotope geochemistry. These tools can be applied to a variety of problems in igneous and metamorphic petrology, structural geology and tectonics, paleobiological evolution and paleoclimate change in deep time.
The IGL infrastructure includes a 750 sq. ft. clean laboratory and mass spectrometry facility, along with supporting mineral separations laboratories in the Department of Geosciences at Boise State University. Details of the Laboratory’s construction and facilities can be found on the IGL Infrastructure page. Visit the IGL Personnel page for profiles of our researchers.
The IGL is a node in the EARTHTIME Network for the Calibration of Earth History. In the spirit of teamwork and cooperation fostered by this initiative, please take a look at our developing LABSHARE archive of analytical procedures used in the IGL for isotope geochemistry and geochronology.
Questions regarding the IGL’s capabilities and services can be referred to: Dr. Mark Schmitz (208-426-5907; markschmitz@boisestate.edu) or Dr. James Crowley (208-426-1121; jimcrowley@boisestate.edu)
