Dear Colleagues,
We encourage you to submit an abstract to our session, 02e: Oxidation State of the Planets at the Goldschmidt 2014 meeting in Sacramento, June 8th-13th. Please, submit your abstract by February 8th at http://goldschmidt.info/2014/abstracts/abstractSubmit
02e: Oxidation State of the Planets
Understanding the redox state of planets and meteorites is necessary to constrain a large range of geologic processes, including the evolution of precursor materials in the early solar system, the generation of planetary cores, the transport of material within planets, the evolution of magmas during degassing and crystallization, and the alteration of material at planetary surfaces. The overall variation in redox conditions in the solar system is at least six orders of magnitude, yet resolving fine-scale variations has become increasingly important to interpreting redox processes within individual planets and asteroids. An overarching challenge in this field has been identifying proxies in rocks that can be used to quantify oxidation state. Recent advances in analytical techniques have added to the ongoing debate about the most accurate tools for constraining oxygen fugacity. Experiments have highlighted the geodynamical significance of understanding how redox-sensitive elements are hosted in planetary interiors, as this may affect depths of melt generation or metal saturation. This session aims to bring together the various communities working on redox processes, from those focused on variations within the Earth, Moon and Mars, to those looking at the redox state of meteorites and their asteroidal parent bodies.
