*GMPV18 The Role of Accessory Minerals in Metamorphic and Igneous Processes
*From: Daniel E. Harlov <dharlov@xxxxxxxxxxxxxx>
**********************************
Hi Folks,
Considering the large attendance and subsequent degree of
participation at last years Accessory Minerals session at the 2006 EGU,
especially the excellent poster session, an Accessory Minerals session
is once again being planned for the 2007 European Geosciences Union
(EGU) General Assembly in Vienna, Austria, April 15 - 20, 2007.
*GMPV18 The Role of Accessory Minerals in Metamorphic and Igneous
Processes*
Silicate, phosphate, oxide, and sulphide accessory minerals play an
important role in helping to decipher the chemical evolution of rocks
over time. They can act both as indicators of chemical states such
fugacity or activity as well as allowing for the dating of metasomatic
events. In addition they also act as repositories for various element
groups such as the (Y+REE) and the actinides. The goal of this session
is to bring together geochemists, petrologists, and mineralogists to
discuss the most recent advances with regard accessory mineral research
as well as relate this research to current general questions in geology
such as how subducting slabs evolve and dehydrate as a function of P-T,
the chemical and physical nature of the lithospheric mantle beneath the
continents, the role of fluids during metamorphism and mineral
equilibration, and the role of fluids in mass transfer in both the lower
crust and upper mantle.
Invited speakers to this session include Mike Williams, University of
Massachusetts-Amherst, who will speak on EMP dating of monazite; Guy
Hovis, Lafayette College, Easton, Pennsylvania, who will speak on
solution calorimetry of synthetic apatites along the F-Cl join; as well
as Mark Harrison, University of California-Los Angeles and Steve
Mojzsis, University of Colorado-Boulder who will both speak on various
aspects of their research concerning Hadean zircons from the Jack Hills
area, Australia.
One of the basic themes of this years session will be to explore how
accessory minerals (e.g. rutile, titanite, monazite, xenotime, apatite,
and zircon) can be used to investigate metasomatic processes in both
metamorphic and igneous rocks in the crust and upper mantle. This theme
includes (and is not limited to) subducting oceanic plates and
subsequent enriched mantle wedges, the role of fluids during high-mid
grade metamorphism, and ore deposition.

*The on-line abstract submission deadline is January 15, 2007.*
Information on the abstract submission process is available at:
http://meetings.copernicus.org/egu2007/how_to_submit_an_abstract.html
East European, Middle Eastern, and African mineralogists,
petrologists, and geochemists are especially encouraged to submit
abstracts. Should any questions arise as to the suitability of the
topic for an abstract to the session, please feel free to contact either
of us (email addresses are given below).
It would be great if you could join us for what will hopefully
prove to be a very diverse and wide ranging session on accessory
minerals in historic as well as ever charming Vienna (
http://www.wien.gv.at/english/ ). We hope to see you there.
best regards,
