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 …

Volatile elements (water, carbon, nitrogen, sulfur, halogens, and noble gases) played an
essential role in the secular evolution of the solid Earth and emergence of life. Here we …

The transport of water from subducting crust into the mantle is mainly dictated by the stability
of hydrous minerals in subduction zones. The thermal structure of subduction zones is a key …

Biotite (sensu lato) is a widespread rock‐forming mineral in magmatic rocks that can be
stable in a broad range of pressure and temperature, but appropriate biotite thermometers or …

Subducted crust refertilizes the subarc mantle wedge as well as the deep convecting mantle.
In the subarc region, mass transfer occurs mainly through fluids, melts, or supercritical …

We have experimentally investigated the fluid-absent melting of a phlogopite peridotite at
1.0 GPa (1000–1300° C) to understand the source of K 2 O-and SiO 2-rich magmas that …

For over 50 years, the use of high-pressure piston/cylinder apparatus combined with an
increasing diversity of microbeam analytical techniques has enabled the study of mantle …

The role of water in the uppermost mantle has been explored to 6 GPa (∼ 200 km) by a
novel experimental approach in which the silicate melting solidus, the stability of hydrous …

Melting experiments have been performed at 3 GPa, between 1150 and 1450° C, on a
phlogopite-peridotite source in the garnet stability field. We succeeded to extract and …

Oceanic transform faults that offset mid-ocean ridges slip through earthquakes and aseismic
creep. The mode of slip varies with depth and along strike, with some fault patches that …
