Dear All Young Scientists, As you know better, 28th is the submission deadline to get financed during the forthcoming EGU. Here are the infomation related with the financial support: http://www.egu2015.eu/support_and_distinction.html Therefore, I invite you to submit your abstract to the session GMPV1.3/SSS5.6 "Phosphorus as a geochemical tracer of petrogenetic processes (co-organized)". For abstract submission and more information about the session - please visit: http://meetingorganizer.copernicus.org/EGU2015/session/17954 On behalf of the conveners of the GMPV1.3/SSS5.6 session, Ioannis Baziotis ---------------------------------------------------------------------- Ioannis Baziotis [log in to unmask] Lecturer Professor of Mineralogy and Petrology Agricultural University of Athens Laboratory of Mineralogy and Geology Athens, 11855 Greece (+30)210-529-4156 GMPV1.3/SSS5.6 Phosphorus as a geochemical tracer of petrogenetic processes (co-organized) Convener: Ioannis Baziotis Co-Conveners: Guil Mallmann , Michael Toplis , Fabrice Brunet The composition of igneous and metamorphic rocks as well as their constituent minerals provide critical information on the geologic history of the Earth and other planetary bodies, including the durations and rates of chemical and thermal events. There has been widespread interest recently in the use of phosphorus (P) — a moderately incompatible and very slowly diffusing element — to constrain the history of mineral growth and timescales of petrogenetic processes. P-rich mineral phases have been identified in many terrestrial and extraterrestrial rocks. However, the processes influencing the formation of P-rich silicates are varied, including among others, non-equilibrium incorporation, melt composition, temperature, oxygen fugacity, and apatite saturation. Additionally, the presence of phosphorus may be critical during partial melting, with high concentrations of P acting to lower the silica content of primary liquids in diverse contexts relevant to planetary or meteorite p arent-body magmatism. In this session we welcome experimental, natural, and computational studies of terrestrial and extra-terrestrial materials focused on, but not restricted to, kinetics, temperature-time estimates, crystal growth rates, melt effects and partitioning of phosphorus.
