Accretionary Prism and Forearc Deformation Driven by the Beata Ridge Indentation in Southern Hispaniola: Insights From the Offshore San Pedro Basin

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract The Cretaceous–Eocene island arc of Hispaniola is currently shortened between the Bahamas carbonate platform to the north and the thickened crust of the Caribbean Large Igneous Province (CLIP) to the south. Within this transpressional setting, the 15–22‐km‐thick, ∼100‐km‐wide Beata Ridge (BR), the thickest portion of the CLIP, acts as a ...

Sediment Provenance Along the Middle Miocene‐Pleistocene Nankai Subduction Zone From Sediment Transport to Accretion: Implications for Stratigraphy in the Accretionary Prism

open access: yesGeochemistry, Geophysics, Geosystems
Based on U‐Pb dating of zircon crystals and petrographic analysis, this study provides new insights into the paleogeographic and accretion evolution along SW Japan.

Accumulation of an earthquake-induced extremely turbid layer in a terminal basin of the Nankai accretionary prism

open access: yesEarth, Planets and Space, 2014
Seismic shaking is a major trigger for sediment redistribution in subduction zones, and clouds of dilute suspended sediment have been reported in association with large earthquakes.

Unconformity between a Late Miocene-Pliocene accretionary prism (Nishizaki Formation) and Pliocene trench-slope sediments (Kagamigaura Formation), central Japan [PDF]

open access: yes, 2012
International audienceUnconformities provide key geological evidence of a major tectonic event, a period without the deposition of sediment, or an environmental change (e.g. Tomkeieff 1962).

Geochemical Characteristics and Their Geological Significance of Zircon and Apatite From the Wunugetushan Porphyry Cu–Mo Deposit, Inner Mongolia, NE China

open access: yesActa Geologica Sinica - English Edition, Volume 100, Issue 3, Page 795-813, June 2026.
The key factors making the monzogranitic porphyry fertile for mineralization, including its high Cl, S, and H2O contents, high oxidation state, significant fluid exsolution, and multiple recharges of deep‐seated mafic magma, were all critical for the formation of the Wunugetushan porphyry Cu‐Mo deposit. ABSTRACT The Wunugetushan (Wushan) porphyry Cu–Mo

Origin and transport of pore fluids in the Nankai accretionary prism inferred from chemical and isotopic compositions of pore water at cold seep sites off Kumano

open access: yesEarth, Planets and Space, 2014
We used push corers during manned submersible dives to obtain sediment samples of up to 30 cm from the subseafloor at the Oomine Ridge. The concentrations of B in pore water extracted from the sediment samples from cold seep sites were higher than could ...

Project: Assessing the state of in-situ stress, deformation properties and consolidation processes in marine clay-rich sediments at the Nankai accretionary prism [PDF]

open access: yes, 2010
Some of Earth's largest earthquakes occur along décollement faults that separate overriding plate and accretionary prism from subducting plate. I conduct a collaborative experimental study to assess in-situ stress state, deformation properties, and ...

How the rigidity of the subducting plate affects the geometry of accretionary prisms? [PDF]

open access: yes
International audienceSimulations of accretionary prisms are most of the time realized either using a simplified set up that cannot account for the evolution of temperature with the growth of the prism nor deformable basement or using a very large size ...

Surficial sedimentary properties of Makran accretionary prism and its application to natural gas hydrate distribution

open access: yesFrontiers in Marine Science
The Makran accretionary prism (MAP) resulted from the low-angle, slow-rate subduction of the Arabian Plate beneath the Eurasian Plate. The MAP is an active continental margin, with natural gas hydrate (NGH).

INTRA-OCEANIC ARCS OF THE PALEO-ASIAN OCEAN

open access: yesГеодинамика и тектонофизика, 2017
Intra-oceanic arcs (IOAs) form at Pacific-type convergent margins, in the upper “stable” plate, when the subducting plate submerges to the depths of melting, i.e., to ca. 50–100 km.
