Fluids in accretionary prisms [PDF]

open access: yesReviews of Geophysics, 1992
Accretionary prisms are composed of initially saturated sediments caught in subduction zone tectonism. As sediments deform, fluid pressures rise and fluid is expelled, resembling a saturated sponge being tectonically squeezed. Fluid flow from the accretionary prism feeds surface biological cases, precipitates and dissolves minerals, and causes ...

Spatiotemporal Characterization of Smectite‐to‐Illite Diagenesis in the Nankai Trough Accretionary Prism Revealed by Samples From 3 km Below Seafloor

Geochemistry Geophysics Geosystems, 2019
The up‐dip limit of seismogenesis in subduction zone forearcs depends on the lithological composition of the incoming sediment and its subsequent modification during compaction and diagenesis.

Sequence stratigraphy, structural style, and age of deformation of the Malaita accretionary prism (Solomon arc–Ontong Java Plateau convergent zone) [PDF]

open access: yesTectonophysics, 2004
Possibilities for the fate of oceanic plateaus at subduction zones range from complete subduction of the plateau beneath the arc to complete plateau–arc accretion and resulting collisional orogenesis.

A viscous accretionary prism

2018
Geodetic observations are commonly used to make inferences about the rheology of the lower crust and mantle, frictional properties of faults, and the structure of the Earth following an earthquake. On 24 September 2013, an Mw 7.7 earthquake ruptured a 200 km segment of the Hoshab fault in southern Pakistan.

Sediment dewatering in the Makran accretionary prism

Earth and Planetary Science Letters, 1985
Abstract Sediments within the Makran accretionary prism are considerably more compacted than the material entering the subduction zone due to the additional tectonic stresses resulting from plate convergence and accretionary processes. Tectonic compaction of the offscraped sediments has been documented by deriving in-situ porosities in the upper 4 km

Mineralogically mature sandstones in accretionary prisms

Journal of Sedimentary Research, 1985
Abstract Plate-tectonic interpretations of sandstone composition are made in the hope that "detrital framework modes of sandstone suites provide information about the tectonic setting of basins of deposition and associated provenances" (Dickinson et al. 1983).

Quaternary deposits on the South Barbados accretionary prism

Marine Geology, 1991
Abstract A study of recent Quaternary deposits of the South Barbados prism has been carried out over a limited area close to the Venezuela margin. 3.5 kHz lines, submarine photographs and many piston and gravity cores have been collected throughout this area during the cruise of the Caracolante II .
