Cenozoic plate motions and the volcano-tectonic evolution of western Oregon and Washington Cenozoic plate motions and the volcano-tectonic evolution of western Oregon and Washington
A refined northeast Pacific plate-motion model provides a framework for analysis of the Tertiary volcanic and tectonic history of western Oregon and Washington. We examine three possible models for the origin of the allochthonous Paleocene and Eocene oceanic basalt basement of the Coast Range: (1) accretion to the continent of hot spot generated linear seamount chains; (2) accretion of...

Shimada Seamount: An example of recent mid-plate volcanism Shimada Seamount: An example of recent mid-plate volcanism
Shimada Seamount is an isolated volcanic feature located between the Clipperton and Clarion Fracture Zones ∼1,150 km west of the East Pacific Rise and ∼600 km west of the inactive spreading center represented by the Mathematician Seamounts. It rises ∼3,900 m above the surrounding sea floor to within 50 m of present-day sea level. The area of Shimada Seamount should be volcanically...
