Seismic evidence for convection-driven motion of the North American plate

  author={David W. Eaton and Andrew W. Frederiksen},
Since the discovery of plate tectonics, the relative importance of driving forces of plate motion has been debated. Resolution of this issue has been hindered by uncertainties in estimates of basal traction, which controls the coupling between lithospheric plates and underlying mantle convection. Hotspot tracks preserve records of past plate motion and provide markers with which the relative motion between a plate’s surface and underlying mantle regions may be examined. Here we show that the… 
Driving forces of plate motion and continental drift: Revisited
The establishment of the theory of plate tectonics at the end of the 1960s provoked quantitative discussions regarding the forces acting on lithospheric plates. Subsequent studies during the earlyto
Seismic evidence for a recently formed mantle upwelling beneath New England
Lateral changes in seismic velocity 100–300 km beneath the Appalachian orogen (eastern North America) do not follow the pattern of its major terranes, suggesting that more recent, and possibly
Absolute plate motions constrained by shear wave splitting orientations with implications for hot spot motions and mantle flow
[1] Here, I present a new absolute plate motion model of the Earth's surface, determined from the alignment of present-day surface motions with 474 published shear wave (i.e., SKS) splitting
Variability and origin of seismic anisotropy across eastern Canada: Evidence from shear wave splitting measurements
Measurements of seismic anisotropy in continental regions are frequently interpreted with respect to past tectonic processes, preserved in the lithosphere as “fossil” fabrics. Models of the
P and S wave tomography of the mantle beneath the United States
Mantle seismic structure beneath the United States spanning from the active western plate margin to the passive eastern margin was imaged with teleseismic P and S wave traveltime tomography including
Modification of continental lithosphere by tectonic processes: A tomographic image of central North America
The assembly of Laurentia by Precambrian accretion is also believed to have formed the underlying lithosphere. Accretionary signatures are detectable by seismic observations but subject to
Seismic anisotropy of Precambrian lithosphere: Insights from Rayleigh wave tomography of the eastern Superior Craton
The thick, seismically fast lithospheric keels underlying continental cores (cratons) are thought to have formed in the Precambrian and resisted subsequent tectonic destruction. A consensus is


Convection‐driven motion of the North American craton: Evidence from P‐wave anisotropy
SUMMARY We study the effect of anisotropy on P-wave traveltimes and generalize Backus (1965) well-known expression of azimuthal velocity dependence to the sphere. The variation of P-wave
The continental tectosphere
Studies of free oscillations and body wave travel times have established that the one-way vertical S wave travel times through the upper mantle average about 5 s greater for oceans than for stable
Shear stress at the base of shield lithosphere
One of the basic unresolved issues regarding plate tectonics is the degree of coupling between surface plates and convecting mantle below. Are the plates effectively decoupled from the mantle flow
Large-scale motion between Pacific and Atlantic hotspots
STUDIES of true polar wander (TPW), the rotation of the solid Earth with respect to the spin axis1, have suggested that there has been 10–15° of relative motion over the past 130 Myr (refs 2–4). In
The Mantle Flow Field Beneath Western North America
This work combines observations of surface deformation and upper mantle seismic anisotropy to estimate this flow field for western North America, finding that the mantle velocity is 5.5 ± 1.5 centimeters per year due east in a hot spot reference frame, nearly opposite to the direction of North American plate motion.
Which forces drive North America
Understanding the mechanism of plate tectonics is one of the most important problems in the geosciences. Are the tectonic plates pulled and pushed from the side, as the Orowan-Elsasser model
On the Relative Importance of the Driving Forces of Plate Motion
Summary A number of possible mechanisms have recently been proposed for driving the motions of the lithospheric plates, such as pushing from mid-ocean ridges, pulling by downgoing slabs, suction
Iceland, the Farallon slab, and dynamic topography of the North Atlantic
Upwelling or downwelling flow in Earth's mantle is thought to elevate or depress Earth's surface on a continental scale. Direct observation of this "dynamic topography" on the seafloor, however, has
How Mantle Slabs Drive Plate Tectonics
From the geologic history of subduction, the relative importance of “pull” versus “suction” for the present-day plates is estimated and observed plate motions are best predicted if slabs in the upper mantle are attached to plates and generate slab pull forces that account for about half of the total driving force on plates.
Shear wave velocity, seismic attenuation, and thermal structure of the continental upper mantle
SUMMARY Seismic velocity and attenuation anomalies in the mantle are commonly interpreted in terms of temperature variations on the basis of laboratory studies of elastic and anelastic properties of
