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 ...

Lithospheric Stress Tensor from Gravity and Lithospheric Structure Models

open access: yesPure and Applied Geophysics, 2017
In this study we investigate the lithospheric stresses computed from the gravity and lithospheric structure models. The functional relation between the lithospheric stress tensor and the gravity field parameters is formulated based on solving the boundary-value problem of elasticity in order to determine the propagation of stresses inside the ...

The subantarctic lithospheric mantle [PDF]

open access: yesGeological Society, London, Memoirs, 2021
Abstract We present a summary of peridotite in the Subantarctic (46–60° S) surrounding the Antarctic Plate. Peridotite xenoliths occur on the Kerguelen Islands and Auckland Islands. The Kerguelen Islands are underlain by a plume, whereas the Auckland Islands are part of continental Zealandia, which is a Gondwana-rifted fragment. Small amounts

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

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).

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.

Thermal Structure of Eastern Australia's Upper Mantle and Its Relationship to Cenozoic Volcanic Activity and Dynamic Topography

open access: yesGeochemistry, Geophysics, Geosystems, 2021
Spatio‐temporal changes of upper mantle structure play a significant role in generating and maintaining surface topography. Although geophysical models of upper mantle structure have become increasingly refined, there is a paucity of geologic constraints
