Record of modern-style plate tectonics in the Palaeoproterozoic Trans-Hudson orogen
OM Weller, MR St-Onge - Nature Geoscience, 2017 - nature.com
Abstract The Trans-Hudson orogen of North America is a circa 1,800 million year old, middle
Palaeoproterozoic continental collisional belt. The orogen may represent an ancient …

A tale of two orogens: Crustal processes in the Proterozoic Trans‐Hudson and Grenville Orogens, eastern Canada
The Precambrian core of North America was assembled in the Proterozoic by a series of
collisions between Archean cratons. Among the orogenic belts, two stand out due to their …

3-D shear wave radially and azimuthally anisotropic velocity model of the North American upper mantle
Using a combination of long period seismic waveforms and SKS splitting measurements, we
have developed a 3-D upper-mantle model (SAWum_NA2) of North America that includes …

Azimuthal seismic anisotropy in the Earth's upper mantle and the thickness of tectonic plates
Azimuthal seismic anisotropy, the dependence of seismic wave speeds on propagation
azimuth, is largely due to fabrics within the Earth's crust and mantle, produced by …

Seismic imaging of the lithosphere beneath Hudson Bay: Episodic growth of the Laurentian mantle keel
The Hudson Bay basin in northern Canada conceals one of the major collisional zones of
the Canadian Shield, the Trans-Hudson Orogen (THO), which marks the Paleoproterozoic …

The development of magmatism along the Cameroon Volcanic Line: evidence from seismicity and seismic anisotropy
Abstract The Cameroon Volcanic Line (CVL) straddles the continent‐ocean boundary in
West Africa but exhibits no clear age progression. This renders it difficult to explain by …
