Kinematics of the Nicaraguan forearc from GPS geodesy [PDF]

Geophysical Research Letters, 2007
Campaign GPS data from a network in the Nicaraguan forearc show a strong component of arc-parallel motion indicating northwest translation of a nearly rigid forearc sliver. Our measured mean velocity for forearc sites of 15.1 mm yr−1 agrees well with the

Serpentinization of the forearc mantle

Earth and Planetary Science Letters, 2003
A wide range of geophysical and geological data indicate that extensive serpentinization in the forearc mantle is both expected and observed. Large volumes of aqueous fluids must be released upwards by dehydration reactions in subducting oceanic crust and sediments. Subduction of oceanic lithosphere cools the overlying forearc such that low temperature

Crustal Architecture of the Cascadia Forearc

Science, 1994
Seismic profiling data indicate that the thickness of an accreted oceanic terrane of Paleocene and early Eocene age, which forms the basement of much of the forearc beneath western Oregon and Washington, varies by approximately a factor of 4 along the strike of the Cascadia subduction zone.

Forearc Stratigraphy and Structure

Offshore Technology Conference, 1977
ABSTRACT Active continental margins and the active flanks of island arcs lie in the forearc regions of arc-trench systems generated by plate consumption. Arc-trench systems are initiated by contractional activation of previously rifted continental margins, by reversal of subduction polarity following arc collisions,

A bathymetric overview of the Mariana forearc

Island Arc, 1998
Bathymetric data at a 200‐m contour interval for the entire Mariana forearc, from south of 13°N to 25°N, permits the first comprehensive overview of this feature. The Mariana forearc represents a sediment‐starved end‐member. The forearc in its southern and central sections is divisible into a structurally complex eastern province and a less‐deformed ...

An experimental investigation of C–O–H fluid-driven carbonation of serpentinites under forearc conditions [PDF]

Earth and Planetary Science Letters, 2018
The carbonation of serpentinites in the forearc region of the mantle wedge in subduction zones and of serpentinites within the subducting slab by fluids derived from prograde dehydration and decarbonation has important implications for the deep Earth ...
