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.

THE GLOBAL ENDODRAINAGE SYSTEM: SOME FLUID-PHYSICAL MECHANISMS OF GEODYNAMIC PROCESSES

open access: yesГеодинамика и тектонофизика, 2019
The article presents the main results of more than forty-year studies of the hydrogeodeformation field. We have establish some new properties of lithospheric massifs, which are clearly detectable during the periods of fast geodynamic activation (FGeDA ...

Sensitivities of surface wave velocities to the medium parameters in a radially anisotropic spherical Earth and inversion strategies

open access: yesAnnals of Geophysics, 2015
Sensitivity kernels or partial derivatives of phase velocity (c) and group velocity (U) with respect to medium parameters are useful to interpret a given set of observed surface wave velocity data.

Analog and Numerical Experiments of Double Subduction Systems With Opposite Polarity in Adjacent Segments

open access: yesGeochemistry, Geophysics, Geosystems, 2020
In this work we study the dynamics of double subduction systems with opposite polarity in adjacent segments. A combined approach of numerical and analog experiments allows us to compare results and exploit the strengths of both methodologies.

Boninite and Harzburgite from Leg 125 (Bonin-Mariana Forearc): A Case Study of Magma Genesis during the Initial Stages of Subduction [PDF]

open access: yes, 1992
Holes drilled into the volcanic and ultrabasic basement of the Izu-Ogasawara and Mariana forearc terranes during Leg 125 provide data on some of the earliest lithosphere created after the start of Eocene subduction in the Western Pacific.

Cenozoic plate driving forces [PDF]

open access: yes, 1995
Past studies of plate driving forces have concluded that the forces due to subducted slabs in the upper mantle and those due to the thickening of the oceanic lithosphere are the principal driving forces. We reexamine the balance of driving forces for the

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.

The westward drift of the lithosphere. A tidal ratchet? [PDF]

open access: yes, 2018
Is the westerly rotation of the lithosphere an ephemeral accidental recent phenomenon or is it a stable process of Earth’s geodynamics? The reason why the tidal drag has been questioned as the mechanism determining the lithospheric shift relative to ...
