Dual-layered mantle lithosphere beneath southeastern Canadian Cordillera [PDF]
Nature CommunicationsThe craton edge beneath southwestern Canada has been characterized as a ‘lithospheric step’ involving the transition from the warm Cordillera to an ancient, mechanically strong North American craton. Using converted shear waves that are sensitive to this

Deformational sequence of inversion in the Paramirim Aulacogen, northern region of the intracontinental sector of the Araçuaí Orogen [PDF]
Brazilian Journal of Geology, 2023 The Paramirim Aulacogen was filled by the Espinhaço and São Francisco supergroups in the period from 1.75 to 0.69 Ga, and suffered partial inversion during the Ediacaran.

Global Patterns in Cratonic Mid‐Lithospheric Discontinuities From Sp Receiver Functions
Geochemistry, Geophysics, Geosystems, 2021 The goal of this study is to constrain the origins of layering in the seismic velocity structure within the cratonic mantle lithosphere (i.e. mid‐lithospheric discontinuities [MLDs]).

Criteries and prospects of diamonds of the Vitebsk granulite massif
Журнал Белорусского государственного университета: География, геология, 2021 The article describes the history of studying the diamond content of tectonic structures of the territory of Belarus. Based on the results of magnetometric, mineralogical, tectonic studies carried out by industrial geologists and scientists over the past

Multi‐Layer Seismic Anisotropy Beneath Greenland
Geochemistry, Geophysics, Geosystems, 2021 Seismic anisotropy provides insight into past episodes of lithospheric deformation and the orientations of strain in the underlying asthenosphere. The Greenland mantle has played host to a rich history of tectonic processes, including multiple orogenies ...

Small Shear Wave Splitting Delays Suggest Weak Anisotropy in Cratonic Mantle Lithosphere
Geophysical Research Letters, 2021 We use splitting in core‐refracted teleseismic shear waves (SKS, PKS, and similar) to investigate anisotropic properties of the upper mantle beneath the Superior craton in eastern North America and the Yilgarn craton in Western Australia.
