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

Solid 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.

Heat Flow Measurements over Bottom Simulating Reflectors, Offshore Southwestern Taiwan

Terrestrial, 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.

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

Results 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.

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

Earth, 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.

The Bunce Fault and Strain Partitioning in the Northern Lesser Antilles

Geophysical 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

Annals 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.

Depth profile of frictional properties in the inner Nankai accretionary prism using cuttings from IODP Site C0002

Progress in Earth and Planetary Science, 2022
We conduct frictional experiments using cuttings collected at Nankai Trough IODP Site C0002 over 980.5–3262.5 mbsf (meters below seafloor) depth interval to better understand the frictional properties through the accretionary prism.

Horizontal shortening versus vertical loading in accretionary prisms [PDF]

Geochemistry, Geophysics, Geosystems, 2009
The analysis of two‐phased deformation of subducted turbidites within the Shimanto Belt on Kyushu (Japan) shows strongly contrasted kinematics between an earlier, noncoxial “fold‐and‐thrust”‐type stage and a later, metamorphic, coaxial vertical shortening stage.

Exhuming an Accretionary Prism: A Case Study of the Kodiak Accretionary Complex, Alaska, USA

Tectonics, 2023
AbstractWe have carried a structural study across Kodiak accretionary complex in Alaska, USA, in order to describe its thermal structure and decipher the processes of exhumation. The accretionary complex consists of a stack of tectonic mélanges and coherent units. Mélanges are characterized by simple shear deformation with a pervasive network of top‐to‐

In-situ mechanical weakness of subducting sediments beneath a plate boundary décollement in the Nankai Trough

Progress in Earth and Planetary Science, 2018
The study investigates the in-situ strength of sediments across a plate boundary décollement using drilling parameters recorded when a 1180-m-deep borehole was established during International Ocean Discovery Program (IODP) Expedition 370, Temperature ...
