Three-layer structure of the Carpathian sedimentary prism from the results of seismic migration on the PANCAKE and RomUkrSeis WARR profiles

open access: yesГеофизический журнал, 2022
The method of finite-difference migration of reflected/refracted waves, applied to the PANCAKE and RomUkrSeis WARR seismic profiles, made it possible to form wave images of sedimentary layer and crystalline basement under the Carpathian orogen to a ...

Stages of Gas-Hydrate Evolution on the Northern Cascadia Margin [PDF]

open access: yesScientific Drilling, 2006
Natural gas hydrate occurs beneath many continental slopes and in arctic permafrost areas. Recent studies have indicated that the largest deposits of gas hydrate might lie in nearly horizontal layers several hundred meters beneath the seafloor of ...

Décollement depth versus accretionary prism dimension in the Apennines and the Barbados [PDF]

open access: yesTectonics, 2003
Along representative cross sections of the Apennines and the Northern Barbados accretionary prisms, we measured the area, the décollement depth, the angle α of the upper envelope and the angle β of the dip of the regional monocline. The continental sections of the Apennines accretionary prism have a deeper décollement than the oceanic sections of the ...

Geothermics of the Apenninic subduction

open access: yesAnnals of Geophysics, 1997
The subduction of the Adriatic microplate is analysed from a geothermal point of view. In particular four main geodynamic units are distinguished: foreland, foredeep and slab, accretionary prism, and back-arc basin.

Heat Flow Measurements over Bottom Simulating Reflectors, Offshore Southwestern Taiwan

open access: yesTerrestrial, Atmospheric and Oceanic Sciences, 2006
The submarine accretionary wedge offshore of southwestern Taiwan consists of an intensively deformed upper slope and a lower slope characterized by mostly west-vergent anticlines and thrusts.

First magmatism in the New England Batholith, Australia: forearc and arc–back-arc components in the Bakers Creek Suite gabbros [PDF]

open access: yesSolid Earth, 2017
The New England Orogen, eastern Australia, was established as an outboard extension of the Lachlan Orogen through the migration of magmatism into forearc basin and accretionary prism sediments.

Moment tensor inversion of the 2016 southeast offshore Mie earthquake in the Tonankai region using a three-dimensional velocity structure model: effects of the accretionary prism and subducting oceanic plate

open access: yesEarth, Planets and Space, 2018
The southeast offshore Mie earthquake occurred on April 1, 2016 near the rupture area of the 1944 Tonankai earthquake, where seismicity around the interface of the Philippine Sea plate had been very low until this earthquake.

Preliminary appraisal of deformation structures from Great Nicobar Island, Andaman-Sumatra arc system

open access: yesResults in Earth Sciences, 2023
The Andaman and Nicobar Group of Islands represent a topographic high of forearc sediments in an actively rising accretionary prism on the Andaman subduction margin.

The Bunce Fault and Strain Partitioning in the Northern Lesser Antilles

open access: yesGeophysical Research Letters, 2019
Strain partitioning related to oblique plate convergence has long been debated in Northern Lesser Antilles. Geophysical data acquired during the ANTITHESIS cruises highlight that the sinistral strike‐slip Bunce Fault develops along the vertical, long ...

Pre-collisional geodynamics of the Mediterranean Sea: the Mediterranean Ridge and the Tyrrhenian Sea

open access: yesAnnals of Geophysics, 1997
Today the Mediterranean Sea consists of a series of small-sized and almost geographically disconnected oceanic or continental crust rooted marine basins.
