********************************************************************************** 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. Please feel free to contact us with questions!
