Physical, chemical, and chronological characteristics of continental mantle

RW Carlson, DG Pearson, DE James - Reviews of Geophysics, 2005 - Wiley Online Library
Unlike in the ocean basins where the shallow mantle eventually contributes to the
destruction of the overlying crust, the shallow mantle beneath continents serves as a stiff …

Global shear speed structure of the upper mantle and transition zone

AJ Schaeffer, S Lebedev - Geophysical Journal International, 2013 - academic.oup.com
The rapid expansion of broad-band seismic networks over the last decade has paved the

Mantle plumes from top to bottom

NH Sleep - Earth-Science Reviews, 2006 - Elsevier
Hotspots include midplate features like Hawaii and on-axis features like Iceland. Mantle
plumes are a well-posed hypothesis for their formation. Starting plume heads provide an …

Continental rifting parallel to ancient collisional belts: an effect of the mechanical anisotropy of the lithospheric mantle

A Tommasi, A Vauchez - Earth and Planetary Science Letters, 2001 - Elsevier
Analysis of major rift systems suggests that the preexisting structure of the lithosphere is a
key parameter in the rifting process. Rift propagation is not random, but tends to follow the …

presented. We developed and applied a new method of simultaneously inverting regional S …

Upper-mantle seismic structure in a region of incipient continental breakup: northern Ethiopian rift

ID Bastow, GW Stuart, JM Kendall… - Geophysical Journal …, 2005 - academic.oup.com
The northern Ethiopian rift forms the third arm of the Red Sea, Gulf of Aden triple junction,
and marks the transition from continental rifting in the East African rift to incipient oceanic …

Effective elastic thickness of South America and its implications for intracontinental deformation

M Pérez‐Gussinyé, AR Lowry… - Geochemistry …, 2007 - Wiley Online Library
The flexural rigidity or effective elastic thickness of the lithosphere, Te, primarily depends on
its thermal gradient and composition. Consequently, maps of the lateral variability of Te in …
