2010 GSA Session: T106  Explosive volcanism across the Solar System
From: "Nicholas Lang" <nlang@xxxxxxxxxxxxxx>

Dear Terrestrial and Planetary Volcano Folks-

We would like to draw your attention to the following session at the
2010 GSA meeting in Denver, CO:

T106.  Explosive volcanism across the Solar System: Insights from
qualitative, quantitative, and geochemical approaches.

Co-sponsored by the Planetary Geology Division and the Mineralogy,
Geochemistry, Petrology, and Volcanology Division.

This is a broad session meant to outline our current knowledge of
explosive volcanism on any planetary body as gained through
qualitative, quantitative, and geochemical approaches in order to
highlight outstanding questions regarding this process.

Invited speakers include Yang Liu (University of Tennessee) and Rosaly
Lopes (JPL)

Rationale:  Volcanism is a dominant process operating on planetary
surfaces and perhaps the most captivating type of volcanism is the
explosive variety.  Although most volcanism that has occurred across
the solar system is believed to be effusive in nature, evidence for
explosive volcanism exists on the surfaces on many planetary bodies.
Aside from Earth, explosive volcanism is interpreted to have occurred
on Mars, the Moon, Venus, Mercury and some outer satellites.  In fact,
the Voyager spacecraft took pictures of a volcanic plume on Io, which
suggests that explosive volcanism may be common there.  On Earth, most
explosive volcanism (or at least prolonged explosive cycles) is
associated with convergent plate boundaries and the absence of obvious
evidence for plate tectonics on other planetary bodies challenges some
of our basic perceptions as to how and why explosive volcanism occurs.
 Specifically, if plate tectonics does not operate outside of Earth,
what triggers, or triggered, explosive volcanism on these other solar
system bodies?  The purpose of this session is to bring together
terrestrial and planetary volcanologists who have studied explosive
volcanism using qualitative, quantitative, and geochemical techniques
in order to outline our current state of knowledge of explosive
volcanism as it has occurred (or is currently occurring) across the
solar system as a means of highlighting some possible ways of using
our limited data of extraterrestrial volcanism to understand volcanic
systems as a whole on other planets.  Both terrestrial and
extraterrestrial volcanologists are encouraged to submit to this
session.  Students conducting research in this area are especially
encouraged to submit.

Abstract deadline is August 10th and the conference runs from October
31st to November 3rd, 2010.
