The many surface expressions of mantle dynamics

J Braun - Nature Geoscience, 2010 - nature.com
Plate tectonic theory suggests that present-day topography can be explained by the
repeated interactions between the tectonic plates moving along Earth's surface. However …

The ups and downs of North America: Evaluating the role of mantle dynamic topography since the Mesozoic

L Liu - Reviews of Geophysics, 2015 - Wiley Online Library
The driving force for transient vertical motions of Earth's surface remains an outstanding
question. A main difficulty lies in the uncertain role of the underlying mantle, especially …

Complex subduction and small-scale convection revealed by body-wave tomography of the western United States upper mantle

Mantle provinces under North America from multifrequency P wave tomography

K Sigloch - Geochemistry, Geophysics, Geosystems, 2011 - Wiley Online Library
This is a survey of mantle provinces (large‐scale seismic anomalies) under North America,
from the surface down to 1500–1800 km depth. The underlying P velocity model was …

Lithosphere–asthenosphere interaction beneath the western United States from the joint inversion of body-wave traveltimes and surface-wave phase velocities

American plate and the processes in the mantle is still not fully documented and understood …

Slab‐plume interaction beneath the Pacific Northwest

M Obrebski, RM Allen, M Xue… - Geophysical Research …, 2010 - Wiley Online Library
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 …

Origin of Columbia River flood basalt controlled by propagating rupture of the Farallon slab

L Liu, DR Stegman - Nature, 2012 - nature.com
The origin of the Steens–Columbia River (SCR) flood basalts, which is presumed to be the
onset of Yellowstone volcanism, has remained controversial, with the proposed conceptual …

Seismically imaged relict slab from the 55 Ma Siletzia accretion to the northwest United States

Teleseismic tomography images a large high-velocity “curtain” extending vertically beneath
the ca. 50 Ma Challis magmatic trend to maximum depths of 230–600 km. We interpret this …

3-D shear wave radially and azimuthally anisotropic velocity model of the North American upper mantle

H Yuan, B Romanowicz, KM Fischer… - Geophysical Journal …, 2011 - academic.oup.com
Using a combination of long period seismic waveforms and SKS splitting measurements, we
