Dear Colleagues,

We encourage you to submit an abstract to 
session 1-5, “Generation, transport, and emplacement of magma in the 
continental crust” at the 2013 IAVCEI General Assembly, to be held in 
Kagoshima, Japan, July 20-24.

The goal of the session is 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.  We wish to 
bring together a diverse group of researchers (geophysicists, 
geologists, and geochemists), who investigate crustal magmatism from 
different perspective in different tectonic environments.  It is hoped 
that this session will foster further multidisciplinary projects in the 
characterization of magma generation and magmatic systems in the 
continental crust.

Abstracts are due January 31, and can be submitted viahttp://www.iavcei2013.com/abstract_submission/abstract_submission.html

All the best for the New Year

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.
