Dear all, Please consider submitting an abstract to the following session at the forthcoming AGU Fall Meeting in San Francisco (15th-19th December 2008). The abstract submission deadline is 10th September 2008, 2359 UT (Universal Time). GP02: Mapping the Internal Architecture of Igneous Systems: Applications of Geophysical and Structural Techniques This session will focus on recent advances in the application of geophysical and structural techniques to visualise the geometry and internal architecture of igneous systems. We invite contributions that have made significant insights into the physical emplacement processes involved in the construction of igneous and volcanic bodies through the application of techniques including anisotropy of magnetic susceptibility (AMS), paleomagnetism, rock magnetism, 2D-3D seismic analysis, gravity-magnetic modelling, remote sensing or tectonic/structural analysis. We are particularly interested in how physical emplacement models can reveal links between igneous systems at various scales from the crustal plutonic-volcanic link to the sub volcanic plumbing of large igneous provinces and individual centres. The use of AMS as a fabric analysis technique is a notable example where very subtle igneous fabrics can be constrained, revealing information about magma flow, accommodation related deformation, source area recognition for extrusive deposits, and the pulsed nature of magma emplacement. This session should provide a common forum for structural geologists, geophysicists, volcanologists and igneous petrologists to discuss the issues related to the physical nature and evolution of igneous systems. It is hoped that through bringing together this diverse mix of geoscientists to discuss physical emplacement models of igneous rocks, there will be a greater appreciation of the importance of physical/structural techniques in understanding igneous systems.
