Geophysical model of the mantle ore-forming system

Геофизический журнал, 2019
The paper deals with a generalized geophysical model of the mantle ore-forming system that covers three main parts: a) the area of origin of the ore substance; b) its transportation zone and c) the area of concentrated ore-formation ― a deposit.

Shear-Wave Splitting and Mantle Flow Beneath the Colorado Plateau and its Boundary with the Great Basin [PDF]

, 2008
Shear-wave splitting measurements from SKS and SKKS phases show fast polarization azimuths that are subparallel to North American absolute plate motion within the central Rio Grande Rift (RGR) and Colorado Plateau (CP) through to the western rim of the ...

Lithospheric structure based on integrated analysis of geological-geophysical data along the DOBREfraction’99/DOBRE-2 profile (the East European Platform —the East Black Sea Basin)

Геофизический журнал, 2018
The continuous DOBREfraction’99/DOBRE-2 WARR and CDP profile of 775 km length with about 100 km overlap was acquired by an international team from Ukraine, Poland, Denmark, USA, Netherlands, Germany, Great Britain and Norway in 1996 and 2007 ...

The application of a gravimetric forward modelling of the lithospheric structure for an estimate of the average density of the upper asthenosphere

Geodesy and Geodynamics, 2019
The average density of 3300 kg m−3 is often attributed for the asthenosphere. In this study, we inspect this value by estimating the average value of the (upper) asthenosphere based on applying the gravimetric forward modelling of major known ...

Transient deformations in the Suez-Sinai area from GPS observations [PDF]

, 2005
We analyze data from four GPS campaigns carried out between 1997 and 2002 on a network of 11 sites in the Suez-Sinai, the area of collision between the African and the Arabian plates.

The Influence of Lithospheric Thickness Variations Beneath Australia on Seismic Anisotropy and Mantle Flow

Geochemistry, Geophysics, Geosystems, 2023
Rapid plate motion, alongside pronounced variations in age and thickness of the Australian continental lithosphere, makes it an excellent location to assess the relationship between seismic anisotropy and lithosphere‐asthenosphere dynamics. In this study,

Tectonic significance of changes in post-subduction Pliocene-Quaternary magmatism in the south east part of the Carpathian-Pannonian Region [PDF]

, 2010
The south-eastern part of the Carpathian–Pannonian region records the cessation of convergence between the European platform/Moesia and the Tisza–Dacia microplate.

Upper Mantle Anisotropic Shear Velocity Structure at the Equatorial Mid‐Atlantic Ridge Constrained by Rayleigh Wave Group Velocity Analysis From the PI‐LAB Experiment

Geochemistry, Geophysics, Geosystems, 2021
The evolution of ocean lithosphere and asthenosphere are fundamental to plate tectonics, yet high resolution imaging is rare. We present shear wave velocity and azimuthal anisotropy models for the upper mantle from Rayleigh wave group velocities from ...

Convergent flow in a two-layer system and mountain building [PDF]

, 2010
With the purpose of modelling the process of mountain building, we investigate the evolution of the ridge produced by the convergent motion of a system consisting of two layers of liquids that differ in density and viscosity to simulate the crust and the
