The Isotope Geology Laboratory at Boise State University is a node in the EARTHTIME Network for the Calibration of Earth History. In the spirit of teamwork and cooperation fostered by the EARTHTIME Initiative, please take a look at our developing archive of analytical procedures used in the BSU IGL for isotope geochemistry and geochronology*.
