Two GSA annual meeting sessions examine the advances in understanding of North American Cordillera tectonic evolution, with an emphasis on the nature of ongoing geological phenomena that are influenced by the lithospheric architecture inherited from past geological events. We invite your participation and encourage you to submit abstracts to this theme, drawing upon structural, petrological, isotopic, and sedimentological research that illuminates plate tectonic processes and lithospheric modifications from Neoproterozoic to Present. We welcome contributions that use geophysical methods and interdisciplinary approaches for accurate characterization of mantle and delimitation of seismic anisotropy to reveal the 3D crustal to deep lithospheric structure of Cordilleran lithosphere.
Abstract submission and conference registration are at: http://community.geosociety.org/2013AnnualMeeting/Home/ .
The abstract deadline is August 6, via https://gsa.confex.com/gsa/2013AM/cfp.epl.
Session descriptions are as follows. We look forward to your abstract submission via and seeing you in the Cordilleran sessions, at the outset of the GSA anniversary meeting in October!
Good wishes,

T111. The Structure and Evolution of the North American Lithosphere: An Integrated Perspective
Geophysical methods have been instrumental in our understanding of the evolution of the North American lithosphere. This session will present examples of integrated investigations of the structure and evolution of the North American lithosphere.
Session Chairs: Kevin Mickus, Missouri State University and G. Randy Keller, University of Oklahoma.
Emails: [log in to unmask]; [log in to unmask]
Sponsors: GSA Geophysics Division; GSA Structural Geology and Tectonics Division; GSA Mineralogy, Geochemistry, Petrology, and Volcanology Division.
P5. Evolution of the North American Cordilleran Lithosphere
Keynote session focused on the geodynamic evolution of the North American Cordillera. Its goal is to integrate the entire tectonic history of the region on the crustal to lithospheric scale, emphasizing the relationship of ongoing geological phenomena to the lithospheric architecture inherited from past geological events.
Sponsors: GSA Structural Geology and Tectonics Division; Geochemical Society; GSA Geophysics Division.
Session Chairs:
Anne F. Sheehan , University of Colorado; Christine Siddoway , Colorado College; and Basil Tikoff , University of Wisconsin.
