Reminder: Goldschmidt 2013 session 11g: Mt. Etna from Source to Surface
From: Wendy Bohrson <bohrson@xxxxxxxxxxxxxxx>
****************************************************************************************
Dear colleagues, We hope that you will consider submitting an abstract to our Goldschmidt 2013 session "Mt. Etna from Source to Surface: Deciphering How a Complex Basaltic Magma Storage and Transport System Works". The full session description is below. Our goal for this theme session is to bring together scientists who work on all aspects of the geology of Etna, including volcanological, geochemical, petrological, and geophysical studies. The enormous data set that exists on Etna means that we know so much about this volcano, but interesting and controversial questions remain. We hope to bring together researchers who are interested in examining these questions from a multi-disciplinary perspective, so that we can build on the important work that has already been done. We are pleased to report that Dr. Patrick Allard will be the keynote for this session. In order to have a dynamic session that represents all aspects of the magmatic system at Etna, we hope that you will submit an abstract. Reminders: Abstract deadline April 12, 2013. Meeting dates August 25-30, 2013. The Goldschmidt 2013 website is http://goldschmidt.info/2013/index.

Etna from Source to Surface: Deciphering How a Complex Basaltic Magma Storage and Transport System Works Conveners: Marco Viccaro, Wendy Bohrson, Antonio Paonita, Giuseppe Puglisi Keynote: Patrick Allard (IPGP, Paris) The petrological and geochemical diversity manifested in eruptive products from Mt. Etna, as well as the geochemical features of the outgassed volcanic fluids, reflect the complex array of processes that occurs as magma ascends from its mantle source region to Earth’s surface. Documenting the relative contributions of mantle vs. crustal components, including fluids, will address the ongoing controversy about the source of geochemical signatures in the basalts as well elucidate the relative roles that mantle plume and subduction zone magmatism play. Quantifying the contributions of mantle and crustal components relies on a full understanding of the nature and extent of magma storage and transport regions, and thus, developing an image of the structure and extent of Etna’s subvolcanic magma system and documenting related physio-chemical constraints are priorities. Decades of intensive field, petrological, geochemical, and geophysical work on Mt. Etna afford an opportunity to tackle critical questions about the origin and evolution of magmas, their storage and ascent paths, and their relationships to geodynamic processes at both regional and local scales. We invite contributions that focus on unraveling the complex geochemical fingerprints observed in Etnean eruptive products and that document characteristics of the associated magma storage zones. Volcanological, geochemical and geophysical investigations as well as macro-scale to micro-scale petrologic studies that contribute toward a broader understanding of how the Mt. Etna volcano system works are particularly welcome.
