Earthquake in central Italy and velocities structure of the mantle

Геофизический журнал, 2018
A three-dimensional P-velocity model of the European mantle built on the Taylor approximation made it possible to analyze the velocity structure of the mantle under the Mediterranean and, in particular, under Central Italy, to a depth of 2500 km. It is

Unified Structural Representation of the southern California crust and upper mantle

Earth and Planetary Science Letters, 2015
We present a new, 3D description of crust and upper mantle velocity structure in southern California implemented as a Unified Structural Representation (USR).

Mantle transition zone thickness beneath Ross Island, the Transantarctic Mountains, and East Antarctica

Geophysical Research Letters, 2008
The thickness of the mantle transition zone beneath Ross Island, and parts of the Transantarctic Mountains and East Antarctic Craton has been mapped using data from the 2000–2003 Transantarctic Mountain Seismic Experiment to determine if, as indicated by

The effective elastic thickness of the India Plate from receiver function imaging, gravity anomalies and thermomechanical modelling [PDF]

, 2006
The range and the meaning of the effective elastic thickness (EET) in continental areas have been subject to controversy over the last two decades. Here we take advantage of the new data set from the Hi-CLIMB seismological experiment to re-estimate the ...

P-wave velocities of the upper mantle of the Tethysalpine geosynclines

Геофизический журнал, 2020
The aim of the work is to calculate the velocity distribution of the longitudinal seismic waves (VP) in the upper mantle at depths from the discontinuity M to 400 km.

Characterization of Viscous Dissipative Heating in the Earth's Mantle Caused by Surface Forces

Geochemistry, Geophysics, Geosystems, 2022
Viscous dissipative heating has long been discussed as a heat source in solid celestial bodies experiencing exogenic forces such as tidal forcing or surface loading.

Rifting and arc-related early Paleozoic volcanism along the North Gondwana margin: geochemical and geological evidence from Sardinia (Italy) [PDF]

, 2012
Three series of volcanic rocks accumulated during the Cambrian to Silurian in the metasediment-dominated Variscan basement of Sardinia. They provide a record of the changing geodynamic setting of the North Gondwana margin between Upper Cambrian and ...

Depth-varying azimuthal anisotropy and mantle flow in the Patagonian slab window

Seismica
Subduction of spreading ridges forms slab windows which perturb the local structure and dynamics of the upper mantle. Slab windows may alter the pattern of mantle flow and serve as portals for the exchange of mantle material between upper mantle ...

The possible nature of the seismic activity of the depths of the Predobudruzhsky trough and the Northern Dobruja

Геофизический журнал, 2013
PeriDobruzha depression and its surrounding belong to border zone of the mantle under the EEP, distinguished by the changes of zero isoline of velocity discrepancies with the depth within the limits of the upper mantle and its transition zone according ...

P-velocity of the upper mantle

Геофизический журнал, 2021
The authors have constructed models featuring seismic P-wave velocity distribution in the upper mantle beneath oceanic, continental and transition regions, such as mid-ocean ridges, basins, trenches, island arcs, and back-arc troughs, Atlantic ...
