How serpentine peridotites can leak through subduction channels

2020
<p>Serpentinized peridotites are weaker than other mantle rocks, with an internal friction coefficient μ<sub>i</sub>~0.3 vs. ~0.6. Therefore they often promote strain localization. Serpentinite is also considerably lower in density (r=2.5-2.6 g/cm<sup>3</sup&gt ...

Carbonation and deformation of oceanic serpentinites in the Elba subduction channel: Evidence for fluid–rock interaction at seismogenic depth

Earth and Planetary Science Letters
We present a multi-disciplinary investigation of the deformation and carbonation history of oceanic serpentinites involved in the plate interface of the Cretaceous-Eocene subduction complex exposed in the Elba Island —an exceptionally well-preserved example of oceanic subduction system.

Timing of subduction and exhumation in a subduction channel: Evidence from slab melts from La Corea Mélange (eastern Cuba)

Lithos, 2011
article i nfo High pressure igneous rocks (tonalites), generated by partial melting of subducted basaltic rocks accreted to the mantle wedge, are present in the La Corea serpentinite-matrix melange (eastern Cuba) as centimeter- to meter-sized blocks and as concordant to crosscutting veins within high-pressure parent amphibolite blocks.

Supply rate of continental materials to the deep mantle through subduction channels

Tectonophysics, 2013
Abstract Geological studies have revealed that continental materials subduct from the Earth's surface via the following three mechanisms: tectonic erosion, sediment subduction, and direct subduction of immature oceanic arcs. Then, the continental materials are transported through subduction channels that are located between subducting slabs and ...

An Ancient Subduction Channel in the Depth Range of Seismogenig Coupling

2007
Active subduction channels cannot be directly investigated due to their inaccessibility for drilling or surface examinations. Only geophysical methods, numerical modeling or sandbox simulations throw light on the shallow parts of currently active subduction channels.
