Analytical Capabilities of the IGL

The Isotope Geology Laboratory is a comprehensive radiogenic isotope and U-Pb geochronological facility directed by Dr. Mark Schmitz and managed by Dr. James Crowley, including mineral separation, clean lab analytical chemistry, and high-precision isotopic analysis by isotope dilution thermal ionization mass spectrometry (ID-TIMS). The menu at left contains links to the tracer isotope systems we routinely analyze for high-precision isotope ratios, including the use of enriched isotopic spikes for isotope dilution analysis.

Our primary expertise in the Isotope Geology Laboratory is U-Pb geochronology of accessory minerals including zircon, baddeleyite, monazite, xenotime, titanite, rutile and apatite, using both high-precision isotope dilution thermal ionization mass spectrometry (ID-TIMS) and in situ high-throughput laser ablation inductively coupled mass spectrometry (LA-ICPMS). Follow the links at left for analytical details of both methods.

We offer a unique set of age analysis services using both of these techniques, either separately or in tandem where applicable. Potential users are encouraged to contact Dr. Mark Schmitz or Dr. James Crowley for costs, sample requirements, and turn-around times for these services. Student research and training opportunities in both of these techniques are also available.
