Dear
Colleagues,
We would like to encourage you
to submit a contribution to our session in the next EGU General Assembly to be
held in Vienna, April 22 – 27, 2012 (for details: http://meetings.copernicus.org/egu2012):
GMPV4.11 “Spatio-temporal
evolution of volcanic systems: the importance of
geochronology”
Invited
Speakers:
Andrew Calvert, USGS, USA
Martine Paterne, LSCE, France
Please note the abstract submission deadline of January 17th
2012.
Please pass this information on to
colleagues and students working in this field.
Age determinations are
critical to understand the evolution in space and time of a given volcano, in
that they contribute to constrain the timing of eruptive events. By linking
geochronology and geochemistry, we can gain an improved understanding of the
processes operating all along the history of a given volcano, from source to
surface. Integration of ages with geomorphology allow to identify any possible
periodicity of volcanic episodes and estimate volcanic output rates and erosion
rates, which are important factors to take into account for hazard assessment.
This session aims at bringing
together state-of-the-art dating methods (radiogenic isotopes, paleomagnetism,
stratigraphy …), spanning scales from mineral to outcrop, to constrain the
history of volcanic systems. We invite presentations targeting theory,
methodology, recent improvements, range of effectiveness (time, scale),
quantitative and qualitative studies, statistics, field and laboratory
investigations, new approaches and applications to volcanology (mapping, hazard
assessment…).
Kind regards,
Aurélie Germa, Ralf Gertisser and Xavier
Quidelleur.
