Upper-plate response to ridge subduction and oceanic plateau accretion, Washington Cascades and surrounding region; implications for plate tectonic evolution of the Pacific Northwest (USA and southwestern Canada) in the Paleogene

The interaction between subduction zones and oceanic spreading centers is a common tectonic process, and yet our understanding of how it is manifested in the geologic record is limited to a few well-constrained modern and ancient examples. In the Paleogene, at least one oceanic spreading center inte...
