Prof. Ilya Bindeman, University of Oregon, USA


The 2-day short course will cover the topics of low and high temperature stable isotope geochemistry with the following format: 2 h each day of advanced introductory lecture, a mid-day short exercise, a lecture on an advanced topic, and a research talk at the end of the day that could be open to other members of the Department.

The low-T stable isotope topic will include traditional (mass-dependent), mass independent O, C, S, H isotope geochemistry of sedimentary record pertinent to: Great oxidation event, maturation of the crust, Snowball earth glaciations, evolution of the chemistry of the oceans, and isotopic box modelling of fluxes affecting lithosphere, hydrosphere, atmosphere and biosphere and related controversies currently discussed in papers and conferences. Novel techniques such as clumped isotope methods will also be discussed. The research lecture may cover the evolution of the continental crust as provided by the technique of triple oxygen isotopes.

The high-T isotope geochemistry topic will deal with magma genesis in the crust and the mantle as viewed from a stable isotopic perspective. The course will touch on hydrothermal processes and magmatic hydrothermal transitions. It will employ recent topics of stable and radiogenic isotope geochemistry of zircon, and its use to unravel magma genesis. Precise triple oxygen isotopic evolution of hydrothermal rocks and water-rock interaction will be discussed. The research lecture may include the discussion of the magmatic evolution of hot spot volcanoes, including Yellowstone.
