Dear colleagues,
We would like to draw your attention to the following session for
Goldschmidt 2012, 24-29 June, in Montréal.
6c. Crystals and glasses as archives of volcanic processes
(co-hosted by Themes 6 and 3)
Co-convenors:
Marc-Antoine Longpré (GEOTOP & McGill University) - m-a.longpre@xxxxxxxxx
Valentin Troll (Uppsala Universitet) - valentin.troll@xxxxxxxxx
John Stix (GEOTOP & McGill University) - john.stix@xxxxxxxxx
Steffen Kutterolf (IFM-GEOMAR) - skutterolf@xxxxxxxxxxxxx
Volcanic eruptions are the consequence of processes that occur in
subterranean magma plumbing systems. The study of quenched melt
(matrix glass and glass inclusions) and crystals erupted at the
Earth’s surface provides a powerful means of reconstructing these
sub-volcanic processes. Coupled with advances in thermodynamic
modelling and experimental petrology, this approach also allows better
estimates of the physico-chemical conditions prevailing in magmatic
systems. This session aims to bring together researchers who use the
composition of crystals and glasses (major, trace and volatile
elements, as well as isotopes) to unravel pre- and syn-eruptive
magmatic processes, magma chamber conditions, and the evolution of
volcanic systems. We are particularly interested in contributions that
investigate eruption trigger mechanisms using petrological and
geochemical data.
Keynote speakers:
Jon Blundy (University of Bristol)
Fidel Costa (Earth Observatory of Singapore)
Please consider submitting an abstract! Deadline February 1st.
