Are There One or More Geophysical Coupling Mechanisms before Earthquakes? The Case Study of Lushan (China) 2013

open access: yesRemote Sensing, 2023
Several possible lithosphere–atmosphere–ionosphere coupling mechanisms before earthquake occurrence are presented in the literature. They are described by several models with different interaction channels (e.g., electromagnetic, mechanics, chemical ...

The growth of lithospheric diamonds [PDF]

open access: yesScience Advances, 2018
The different habits of lithospheric diamonds are formed from the same fluids, from redox reactions at isotopic equilibrium.

A Comparison of Gravimetric, Isostatic, and Spectral Decomposition Methods for a Possible Enhancement of the Mantle Signature in the Long-Wavelength Geoidal Geometry

open access: yesRemote Sensing, 2023
A long-wavelength geoidal geometry characterizes the most pronounced features of the Indian Ocean geoid low and the West Pacific and North Atlantic geoid highs.

Measuring and Modeling Viscoelastic Relaxation of the Lithosphere with Application to the Northern Volcanic Zone, Iceland [PDF]

open access: yes, 2010
Viscoelastic relaxation of the stress perturbation caused by an earthquake or diking event can produce measurable ground deformation over 100 km away from the source. We consider the role of viscoelastic relaxation in two different contexts.

Orthopyroxene-enrichment in the lherzolite-websterite xenolith suite from Paleogene alkali basalts of the Poiana Ruscă Mountains (Romania)

open access: yesGeologica Carpathica, 2015
In this paper we present the petrography and geochemistry of a recently collected lherzolite-websterite xenolith series and of clinopyroxene xenocrysts, hosted in Upper Cretaceous–Paleogene basanites of Poiana Ruscă (Romania), whose xenoliths show ...

Discoidal Structure of the Lithosphere [PDF]

open access: yesProceedings of the National Academy of Sciences, 1919
Advanced Summary The following discussion seeks to determine inductively the structural character of the lithosphere at depths beyond the reach of observation. The mechanical state of the outer shell of the lithosphere is discussed on the basis of Adams’ experiments with rocks under confining pressures, which demonstrate that pressure increases the ...

Buckling of the oceanic lithosphere from geophysical data and experiments

open access: yes, 1992
Two major hypothesis have been advanced for the formation of the long wavelength (100-300) km undulations of oceanic basement and overlying sediments developed in the central Indian Ocean: whole layer folding (buckling) and local thickening (inverse ...

Estimation of the effective elastic thickness of the lithosphere: progress and prospects

open access: yes地球与行星物理论评, 2022
The lithospheric strength is a key factor in controlling the lithosphere dynamics and deformations. The effective elastic thickness (Te) of the lithosphere can always be used to address the lithospheric strength. Hence, it is a powerful tool for studying

What is the lithosphere?

open access: yesEos, Transactions American Geophysical Union, 1984
What is the lithosphere? What things subduct, what things do not, and why? How is the lower continental crust formed? Where are the large‐ion lithophile elements stored? Is the style of plate tectonics episodic? These and related questions were considered during a workshop held at the University of Texas at Austin in March 1982 under the sponsorship of
