interested and being eligible for financial support (for requirements
please visit: http://www.egu2015.eu/support_and_distinction.html) - your abstract must be submitted before 28th November,
2014.
For all the other
scientists, the
abstract submission deadline is the 7th of January, 2015
(for abstract submistion and more information about the session

Phosphorus as a geochemical tracer of
petrogenetic processes (co-organized)

Abstract
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 parent-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.
