Short Course GSA 2013


Simultaneous isotopic (e.g., U/Th-Pb) and elemental analysis of minerals by laser ablation split-stream ICP mass spectrometry (LASS) is the latest tool for addressing tectonic & petrologic questions. This course will introduce the types of isotopic and elemental analyses that are possible and show how in situ analyses of accessory minerals in thin section can be applied to quantify igneous, metamorphic, and sedimentary processes. This practical course is aimed at faculty members, researchers, graduate students, and undergraduate students who are interested in learning more about the state-of-the-art in petrochronologic research.
