Welcome to the Isotope Geology Laboratory!

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 in situ and 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 class 10 clean laboratory, thermal ionization mass spectrometry facility, and laser ablation inductively coupled plasma mass spectrometry laboratory, along with supporting rock preparation, mineral separations, and optical & electron beam imaging 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 the recipient of an NSF Instrumentation & Facilities Laboratory Technician Support grant, and Dr. Corey Wall serves in this capacity with a key role in experimental design, training, and implementation of geochronological projects with NSF-funded researchers. The IGL is also 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 (markschmitz@boisestate.edu), Dr. James Crowley (jimcrowley@boisestate.edu), or Dr. Corey Wall (coreywall@boisestate.edu).

Samples can be shipped c/o Dr. Schmitz to the address in the footer of this page.  Before shipping samples to the IGL, please complete the sample template and forward to iglinfo@boisestate.edu.
