Processes taking place in subduction zones are the main controller of the chemical cycle of
volatile and incompatible elements in the Earth system. Metamorphic devolatilization …

The chemistry of hypercoordination has been a subject of fundamental interest, especially
for understanding structures that challenge conventional wisdom. The small ionic radii of Fe …

Abstract Knowledge of volatile cycling is vital to understanding the evolution of the planet
and the life it supports. Although it has been gradually accepted that the mantle is a vast …

At sub‐arc depths, the release of carbon from subducting slab lithologies is mostly controlled
by fluid released by devolatilization reactions such as dehydration of antigorite (Atg‐) …

Abstract Phase A (Mg7Si2O8 (OH) 6) is one of the important dense hydrous magnesium
silicates in subducting slab, because it forms after the breakdown of antigorite serpentine …

To better understand processes above subducted oceanic slabs, we have undertaken
experiments with juxtaposed sediment and peridotite layers at pressures of 7.5 and 10.5 …

Humite-group minerals play a crucial role in transporting water and fluorine to the Earth's
deep mantle through slab sinking. In this study, we have used Brillouin scattering to …

We present experimentally determined partition coefficients (D min/melt) for F and Cl
between pargasite (amphibole), phlogopite (mica), clinopyroxene and basanitic melts. All …

Clinohumite is a potentially abundant silicate mineral with high water concentration (2~ 3
wt% H 2 O) that is generated from dehydration of serpentine-group minerals in subduction …

Calcium (Ca) phosphates are major hosts for phosphorus, halogens and incompatible trace
elements in the Earth's crust and mantle and, by supplying almost all phosphorus to the …
