Serpentinization is a key phenomenon for understanding the geodynamics of subduction
zones in the 10–200 km depth range. Serpentines are a major water carrier, and their …

Permeabilities in the subducting slab appear to be too low and dihedral angles between
fluid and relevant minerals too high to allow for porous flow, hence fluid channelization is …

Water within the oceanic lithosphere is returned to Earth's surface at subduction zones.
Observations of metamorphosed veins preserved in exhumed slabs suggest that fluid can …

Deformation experiments were conducted in a Griggs-type apparatus to constrain the
rheology of antigorite serpentinite at high temperatures and pressures. Samples deformed at …

Hydrogen is a major constituent in a wide variety of minerals in the Earth's crust. Usually H is
bonded to oxygen forming H2O molecules or OH− groups. In rare cases, H3O+, H3O2− and …

Trench-parallel seismic anisotropy has been observed in many subduction zones in the
upper mantle. In this study, the crystal-preferred orientation (CPO) and seismic anisotropy of …

The Monviso meta-ophiolite complex (Northern Italy, Western Alps) represents an almost
intact fragment of Tethyan oceanic lithosphere metamorphosed at~ 80 km depth (~ 2.6 GPa …

Metamorphic olivine formed by the reaction of antigorite+ brucite is widespread in
serpentinites that crop out in glacier-polished outcrops at the Unterer Theodulglacier …

Intermediate-depth earthquakes are common in the double seismic structures of many
subduction zones under high pressures (~ 1–4 GPa). Serpentine dehydration exhibits well …

In the subducting oceanic lithosphere, a significant part of the seismicity is triggered in the
mantle, especially along the upper and lower Wadati-Benioff planes. Several studies have …
