Experimental constraints on the strength of the lithospheric mantle [PDF]

Journal of Geophysical Research: Solid Earth, 2010
To provide a better understanding of rheological properties of mantle rocks under lithospheric conditions, we carried out a series of experiments on the creep behavior of polycrystalline olivine at high pressures (∼4–9 GPa), relatively low temperatures (673 ≤ T ≤ 1273 K), and anhydrous conditions, using a deformation‐DIA. Differential stress and sample

Modification of Crust and Mantle Lithosphere Beneath the Southern Part of the Eastern North American Passive Margin

Geophysical Research Letters, 2021
The eastern North American passive margin was modified by Mesozoic rifting. Seismic data from recent deployment of onshore and offshore stations offer a unique opportunity for studying the signature of syn‐rifting and postrifting in lithospheric ...

Western US intraplate deformation controlled by the complex lithospheric structure

Nature Communications
The western United States is one of Earth’s most tectonically active regions, characterized by extensive crustal deformation through intraplate earthquakes and geodetic motion.

The Deep Lithospheric Structure of the South Australian Craton Revealed by Teleseismic Rayleigh Wave Tomography

Seismica
We used teleseismic Rayleigh waves recorded by three recent broadband seismic arrays in southern Australia to develop a shear wave velocity model of the South Australian Craton from the lower crust to 250 km depth and compare this with isotope data ...

East Pilbara high heat flow mantle overturns as a record of lithospheric proto-plate formation

, 2023
The ca. 3.6-3.2 Ga East Pilbara Terrane (EPT) formed by a distinct vertically accretive geodynamic mode during predicted highest planetary heat flow, prior to the onset of Wilson-style plate tectonics at ca. 3.2 Ga. Three major greenstone volcanic cycles

LIMA U-Pb ages link lithospheric mantle metasomatism to Karoo magmatism beneath the Kimberley region, South Africa

, 2014
The Karoo igneous rocks (174–185 Ma) of southern Africa represent one of the largest continental flood basalt provinces on Earth. Available evidence indicates that Karoo magmas either originated in the asthenosphere and were extensively modified by ...

A Global Plate Model Including Lithospheric Deformation Along Major Rifts and Orogens Since the Triassic

Tectonics, 2019
Global deep‐time plate motion models have traditionally followed a classical rigid plate approach, even though plate deformation is known to be significant.

The backarc mantle lithosphere in Patagonia, South America

Journal of South American Earth Sciences, 2004
The backarc Patagonia mantle underwent pervasive regional re-crystallisation that left only remnants of the pre-existing mantle. Anhydrous xenoliths (dominantly lherzolites and harzburgites, few dunites) are predominant. Xenoliths containing hydrous phases (lherzolites and harzburgites, rare wehrlites) abundantly occur only at G. Gregores.
