  • Hands-on activities

September 10th–13th:
  • Field-trip in the Dolomites, Italian Alps
Lectures and discussions:

Session 1: Oxygen fugacity of rocks and magmas: concepts, thermodynamics and experimental modelling
  • P. Sossi, H. O’Neill - Oxygen fugacity of rocks and magmas: geological and thermodynamic concepts
  • E.C.R. Green - The meaning of fO2 in thermodynamic modelling of petrogenetic processes
  • J. Blundy - The control and monitoring of fO2 in experimental petrology

Session 2: Redox-sensitive elements and state-of-the-art analytical techniques
  • C. McCammon - The oxidation state of Fe through Mössbauer spectroscopy
  • A. Berry - The oxidation state of Fe through XANES
  • Paolo Sossi - Stable isotope redox proxies (Fe, V, Cr)

Session 3: The redox states of Earth’s reservoirs and their relevance for the cycle of elements and atmosphere/biosphere evolution
  • D. Giovannelli - How is the biosphere affected by magmatic processes?
  • A. Aiuppa - Volcanic gas release to the atmosphere
  • R. Moretti - The connection between gas release and composition to the oxidation state of magmas
  • D. Baker - The role of fO2 and S in magmas and volcanic degassing and the links to mass extinction events
  • E. Cottrell - The oxidation state of magmas at mid ocean ridges and subduction zones
  • J. Blundy - Redox processes in magmas and the formation of ore deposits
  • K. Evans - Key redox processes above subducting slabs
  • G. Yaxley - Redox processes during mantle melting and mantle metasomatism
  • D. Frost - Oxidation state of the Earth from the core to the mantle transition zone


Goals of the School:
  • to provide a multidisciplinary outlook on the meaning of oxygen fugacity in planetary reservoirs and processes
  • to review the state-of-the-art knowledge on the oxidation state of the different reservoirs in the Earth and other planetary bodies, and what is the expected speciation of redox-sensitive elements in these reservoirs
  • to pinpoint which are thought to be the major redox-controlling processes in the Earth
  • to provide hands-on activities on Mössbauer and XANES data processing and on computer programs used to model the pressure, temperature and oxygen fugacity of geological systems
  • to provide the participants the opportunity to show and discuss their own case study with some of the major experts in the field
