Mantle dynamics beneath the Pacific Northwest and the generation of voluminous back‐arc volcanism

Mantle dynamics beneath the Pacific Northwest and the generation of voluminous back‐arc volcanism

The Pacific Northwest (PNW) has a complex tectonic history and over the past ∼17 Ma has played host to several major episodes of intraplate volcanism. These events include the Steens/Columbia River flood basalts (CRB) and the striking spatiotemporal trends of the Yellowstone/Snake River Plain (Y/SRP...
