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.

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 ...

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

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

Rejuvenation of the lithosphere by the Hawaiian plume [PDF]

open access: yesNature, 2004
The volcanism responsible for creating the chain of the Hawaiian islands and seamounts is believed to mark the passage of the oceanic lithosphere over a mantle plume. In this picture hot material rises from great depth within a fixed narrow conduit to the surface, penetrating the moving lithosphere.

Rifts, orogens, cratons, and global tectonics: Introduction

open access: yesГеодинамика и тектонофизика, 2017
A key role in developing the Earth theory is played by comparative studies of orogens, rifts, and platforms in the equatorial, middle and high latitudes of Asia and the adjacent Arctic regions.

Altered Mantle Fabric Beneath the Mid‐Continent Rift

open access: yesGeochemistry, Geophysics, Geosystems, 2021
We present new, densely sampled shear‐wave splitting results from southern Minnesota and adjacent areas of neighboring states, sampling the southwestern limit of the Archean Superior Province and straddling the Proterozoic Mid‐Continent Rift (MCR).
