A mantle convection perspective on global tectonics

N Coltice, M Gérault, M Ulvrová - Earth-science reviews, 2017 - Elsevier
The concept of interplay between mantle convection and tectonics goes back to about a
century ago, with the proposal that convection currents in the Earth's mantle drive …

A review of mechanisms generating seismic anisotropy in the upper mantle

LN Hansen, M Faccenda, JM Warren - Physics of the Earth and Planetary …, 2021 - Elsevier
Seismic anisotropy is a key observational tool for mapping flow in Earth's upper mantle.
However, interpreting patterns of anisotropy relies on a firm understanding of the …

The brittle‐plastic transition, earthquakes, temperatures, and strain rates

P Molnar - Journal of Geophysical Research: Solid Earth, 2020 - Wiley Online Library

We used electron backscatter diffraction (EBSD) methods to study the crystallography of
olivine and other minerals in seven heavily metamorphosed (petrographic type 6 or 6/7) but …

Numerical exploration of factors that control stress amplification in Earth's lithosphere

H Feng, CC Gerbi, SE Johnson - Geophysical Journal …, 2023 - academic.oup.com
