Dear
all,
Please
consider submitting an abstract to the following session at the forthcoming
AGU Fall Meeting in
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.

We
hope to attract a diverse mix of igneous emplacement related studies. Please don't hesitate to contact one of the convenors if you have
any questions about this session.
