Short course description

Over the last decade, petrochronology has emerged as a burgeoning new field in Solid Earth Geosciences. It greatly enhances the impact of isotopic studies by combining geochronology with petrology and geochemistry. The Mineralogical Society of America (MSA) decided to dedicate a volume of its RiMG (Reviews in Mineralogy and Geochronology) Series to Petrochronology. Editors are M.J. Kohn (Boise State, USA), M. Engi and P. Lanari (both University of Bern, Switzerland).

Petrochronology basically uses geochemistry, textures, and thermodynamics or other modeling to integrate ages in a petrogenetic context of individual crystals or crystal domains. Examples in metamorphic systems include the use of crystal domain-specific trace element patterns or thermometers in minerals like zircon, monazite, etc. to link an age to an overall Pressure-Temperature-time evolution. Although primarily founded in metamorphic studies, petrochronology has numerous other applications to igneous and detrital mineral studies. Our goal in the short course is to review petrochronologic methods, both conceptual and analytical, to illustrate how (mostly accessory) minerals may be used to understand igneous and metamorphic processes and the provenance of detrital grains. This workshop will provide an important foundation accessible to high-level undergraduate students, graduate students, and junior professional researchers who are interested in the theory and applications of this blossoming new field.

This 1 1/2 – day short course on Friday, Oct. 20 and the morning of Saturday, Oct. 21 will involve a series of lectures from leaders in the scientific fields of magmatic and metamorphic petrology and geochronology. One author will present each of the following chapters of the RiMG volume:

  • Petrochronology: Introduction and Overview (Martin Engi, Pierre Lanari and Matthew Kohn)
  • Phase relations and reaction sequences (Chris Yakymchuk, Chris Clark, and Richard White)
  • Bulk composition effects on mineral parageneses (Pierre Lanari and Martin Engi)
  • Diffusion (Matt Kohn and Sarah Penniston-Dorland)
  • Methods 1: Electron microprobe (Mike Williams and Mike Jercinovic)
  • Methods 2: LA-ICP-MS and LA-SS (Andrew Kylander-Clark)
  • Methods 3: TIMS (Blair Schoene and Ethan Baxter)
  • Minerals 1: Detrital zircon – the Hadean (Mark Harrison, Beth Ann Bell, and Patrick Boehnke)
  • Minerals 2: REE minerals: monazite, allanite, xenotime and apatite (Martin Engi)
  • Minerals 3: Titanite (Matt Kohn)
  • Minerals 4: Garnet (Ethan Baxter, Mark Caddick, and Besim Dragovic)

Travel grants for students

Through support from NSF and the Geochemical Society, we will provide for students:

  • Up to $250 to cover hotel costs (maximum of 25 students). No application is necessary: first come, first served.
  • 4 travel grants of $500. Interested students should submit a 1-page (or less) proposal to Matt Kohn at Boise State University (see email link below) explaining financial need, other sources of travel funds, and importance to your research. Please have your advisor attest to your status and funding sources. Please also include a current CV.
  • Travel grant application deadline = August 1.
