Dear Colleagues,
We would like to draw your attention to a session at the upcoming Goldschmidt
2015 conference (Prague, August 16th-21st) on sulfur in magmatic processes, particularly those
relating to redox and degassing. Many exciting advances in microXANES,
melt inclusion studies, sulfur isotope analyses by ion microprobe and
laboratory experiments make this an ideal time for facilitating a
conversation amongst workers dealing with this complex and important
topic. We hope you and your students will consider participating by
submitting an abstract to this session (abstract submission deadline is April 2nd).
Sincerely,
Rita Economos, Marc-Antoine Longpré, Marie Edmonds and Roberto Moretti
17e: Sulfur: Trace but Mighty in Redox, Degassing, Magmatic Processes, and Mineralization
The last 5 years have seen significant advances in understanding of the behavior of sulfur as a trace element in magmatic systems at the macro- and micro-scales. First-order models and thought-provoking results inform sulfur cycling in systems as large as magmatic arcs and on timescales of mantle recycling. These systems are being approached from mass-balance and novel isotopic perspectives. The complex relationship between sulfur and redox is being explored empirically at the global level and in experimental and equilibrium modeling environments. In addition, sulfur solubility in silicate melts and the saturation behavior of sulfur-bearing phases are enlightened by the application of micro-XANES analyses to experimental and natural samples. This session will bring together researchers working on sulfur and its role in global and local redox, degassing, magmatic processes, and mineralization.
