UPDATE AND FINAL REMINDER: Session 1-5 at 2013 IAVCEI General Assembly - “Generation, transport, and emplacement of magma in the continental crust”
From: Shan de Silva <desilvas@xxxxxxxxxxxxxxxxxxx>
****************************************************************************************
Dear Continental magmatism colleagues
As the deadline for IAVCEI approaches, we are delighted to report that Jim Quick (SMU) and George Bergantz (U. Washington) have accepted invited presentation slots at the session. Other "invited" slots will be chosen based on submissions to the session.
We once again encourage you and your post-docs and students to offer a presentation for the session below on your perspectives on continental magmatism. In order to draw a distinction between Session 1-4b, we will feature presentations on processes of origin, mass and thermal balances, and magma transport, crustal-scale architecture and time-scales.
We hope you accept this invitation and look forward to seeing you at IAVCEI.
With best wishes,
Katsuya KANEKO (Kyoto University),
Mitsuhiro NAKAGAWA (Hokkaido University)
Shanaka DE SILVA (Oregon State University)
Abstracts are due January 31, and can be submitted via http://www.iavcei2013.com/abstract_submission/abstract_submission.html
Session description:
Igneous activity in continental crust produces volcanoes and plutonic bodies with various geometries and magmatic compositions that reflect crustal evolution and construction. For example, we see supervolcanoes and batholiths of felsic rock, stratovolcanoes of intermediate composition, and shield volcanoes, flood basalts, and gabbroic plutons of mafic rock. This variety reflects the interplay of mantle derived magmas and continental crust in the context of tectonic environment. In this session, we hope to explore magmatic processes in the continental crust from the generation of magma in the lower crust, its subsequent evolution through the crust leading to the formation of shallow magma storage zones and plutonic bodies and how these processes are reflected by the volcanic record. Specific questions that we hope to address include: What are the physical and petrological processes in the lower crust that lead to the formation, segregation and transport of magmas. At what levels in the crust does magma evolution take place, what transformations take place and how do we detect these? Why does magma stall in shallow reservoirs at pre-eruptive levels and what controls whether a magma erupts or forms a pluton? What determines the type of volcanism that occurs? What are the characteristics rates and material balances that characterize these processes and what are various approaches we use to decipher these? Understanding crustal magmatism remains a major challenge for the community but is critical for a complete understanding of earth's volcanism and associated hazards. Progress requires a multidisciplinary approach and we hope to attract contributions from geological, geochemical, and geophysical and modeling perspectives.
