Slab‐plume interaction beneath the Pacific Northwest

  title={Slab‐plume interaction beneath the Pacific Northwest},
  author={Mathias Obrebski and Richard M Allen and Mei Xue and G C Shu and Huei Hung},
[1] The Pacific Northwest has undergone complex plate reorganization and intense tectono‐volcanic activity to the east during the Cenozoic (last 65 Ma). Here we show new high‐resolution tomographic images obtained using shear and compressional data from the ongoing USArray deployment that demonstrate first that there is a continuous, whole‐ mantle plume beneath the Yellowstone Snake River Plain (YSRP) and second, that the subducting Juan de Fuca (JdF) slab is fragmented and even absent beneath… CONTINUE READING
