Over the last decades, numerous studies have emphasized the role of serpentinites in the
subduction zone geodynamics. Their presence and role in subduction environments are …

Subduction zones not only return oceanic lithosphere into the mantle, but are also sites
where chemical components are transferred from the downgoing plate back to the surface in …

The water cycle at subduction zones remains poorly understood, although subduction is the
only mechanism for water transport deep into Earth. Previous estimates of water flux,–exhibit …

We present a new synthesis of oceanic crustal structure from two‐dimensional seismic
profiles to explore differences related to spreading rate and age. Primary results are as …

The subducting oceanic lithosphere may carry a large amount of chemically bound water
into the deep Earth interior, returning water to the mantle, facilitating melting, and hence …

The amount of H2O subducted to postarc depths dictates such disparate factors as the
generation of arc and back‐arc magmas, the rheology of the mantle wedge and slab, and …

We provide new insights into the geochemistry of serpentinites from mid-ocean ridges (Mid-
Atlantic Ridge and Hess Deep), passive margins (Iberia Abyssal Plain and Newfoundland) …

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 …

Crustal assimilation (eg Hildreth and Moorbath, 1988) and/or subduction erosion (eg Stern,
1991, Kay et al., 2005) are believed to control the geochemical variations along the northern …

Based on a compilation of published and new seismic refraction and multichannel seismic
reflection data along the south central Chile margin (33°–46° S), we study the processes of …
