ASIF Seminar – C. Bataille: “The strontium isotope “nose”: tasting rocks, water and bones”
December 12 @ 3:30 PM - 4:30 PM
Associated with the installation of the new MC-ICPMS at UAF, the Alaska Stable Isotope Facility has organized a special seminar related to applications of this new facility.
“The strontium isotope “nose”: tasting rocks, water and bones” by Dr. Clement Bataille, Department of Earth and Environmental Sciences, University of Ottawa.
Abstract: Strontium isotope ratio (87Sr/86Sr) has a strong potential to complement other isotope markers (e.g hydrogen or oxygen isotope systems) in provenance studies because strontium (Sr) in Earth surface reservoirs is sourced from local bedrock. As such, 87Sr/86Sr variations are discrete and differ drastically from the large scale smoothed variations of atmospherically-derived stable isotopes. Among the most successful recent applications, 87Sr/86Sr has been used to interpret provenance of individuals in archeology, and to reconstruct animal or material movement pathways. A prerequisite to apply the 87Sr/86Sr geolocation tool is to generate robust spatial 87Sr/86Sr predictions on the Earth’s surface (also called “isoscape”). In this presentation I will review and present new advances to generate Sr isoscapes in terrestrial and fresh-water environments and show how they can be used for exciting environmental applications.
