T51B:
Geologic and Geodynamic Evolution of the Arctic Region II Posters


Session ID#: 8222

Session Description:
Over the last quarter century, scientific and entrepreneurial agendas for the Arctic have expanded greatly as climate change, international politics and technological innovations have diminished logistical barriers and opened a modern frontier for scientific and resource exploration. Despite years of study, much of the framework geologic history of the Arctic Ocean and its surrounding landmasses is insufficiently constrained by existing data and is thus controversial.  Elucidating the multiphase plate tectonic history of the oceanic and surrounding continental realms through robust plate reconstructions and regional tectonic syntheses is a fundamental challenge. We seek research that addresses the challenging geology of the Arctic, especially submissions that integrate understanding of (1) age, lithology, structure, and/or paleo-(bio)geography of circum-Arctic lithosphere, (2) tectonic and geodynamic processes of lithosphere generation and modification, and (3) geologic and geophysical correlations across the oceanic realm and into better-studied regions of Eurasia, Laurentia and elsewhere.
