Geophysical imaging of a tilted mantle plume extending at least 500 km beneath the
Yellowstone caldera provides compelling support for a plume origin of the entire …

Integration of geophysical and geological data show that the Yellowstone hotspot resulted
from a mantle plume interacting with the overriding North America plate, a process that has …

We present a review of seismological constraints on deep crustal structures underlying large
igneous provinces (LIPs), largely from wide‐angle seismic refraction surveys. The main …

Fundamental features of the geology and tectonic setting of the northeast-propagating
Yellowstone hotspot are not explained by a simple deep-mantle plume hypothesis and …

The timing and duration of surface uplift associated with large igneous provinces provide
important constraints on mantle convection processes. Here we review geological indicators …

The relation between the complex geological history of the western margin of the North
American plate and the processes in the mantle is still not fully documented and understood …

The Columbia Plateau, Oregon Plateau, Snake River Plain, and Northern Nevada Rift
compose a single magmatic system containing all the essential characteristics ascribed to a …

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 …

The High Lava Plains province (HLP) is a late Cenozoic bimodal volcanic field at the
northern margin of the Basin and Range province in southeastern Oregon that hosts a …

A new category of large-scale volcanism, here termed Snake River (SR)-type volcanism, is
defined with reference to a distinctive volcanic facies association displayed by Miocene …
