T026:
Multidisciplinary advances in the study of the Northern Cordillera of North America





Session ID#: 25691

Session Description:
The Northern Cordillera is a complex and enigmatic tectonic mosaic. We propose to bring together geoscientists engaged in multidisciplinary studies of slab window dynamics, insipient ridge subduction, ocean-continent transform faulting, and the collision of an oceanic plateau (Yakutat) into a continental margin. The session seeks to facilitate future investigations by examining results from diverse approaches that seek to understand stress transfer deep into continental interiors and how it produces distributed deformation across a zone >500 km wide. An increase in induced seismicity in the Cordilleran foreland, combined with natural seismicity, poses a significant hazard to infrastructure and highlights the need to better know its origins. Multi-scale integration of surficial processes with deeper lithospheric and mantle structures for understanding cordilleran dynamics will be of particular interest in this session. We seek contributions from broad sub-disciplines of geoscience focused on the Northern Cordillera, including surficial geology, geochronology, tectonics, geophysics, petrology, and geochemistry.
