T11A:
An Appraisal of Global Continental Crust: Structure and Evolution I Posters


Session ID#: 9107

Session Description:
The availability of broadband geophysical arrays, such as recent deployments of dense networks across North America and Asia, has substantially increased our ability to characterize crustal properties beneath major continents.  The improved data constraints, coupled with numerical simulations, enable an in-depth analysis of the structure, composition, spatial variability and evolution of the continental crust. This session invites contributions that enhance the current understanding of continental crust from disciplines that include, but are not limited to, seismology, geodynamics, gravity, magnetics and geochemistry.
