The concentration and distribution of water in the Earth has influenced its evolution
throughout its history. Even at the trace levels contained in the planet's deep interior (mantle …

Rutile is the most common naturally occurring titanium dioxide polymorph and is widely
distributed as an accessory mineral in metamorphic rocks ranging from greenschist to …

Most minerals of Earth's upper mantle contain small amounts of hydrogen, structurally bound
as hydroxyl (OH). The OH concentration in each mineral species is variable, in some cases …

Discovery of coesite, diamond, and extreme 18O-depletion in eclogites from the Dabie–Sulu
orogen in central-east China has contributed much to our understanding of subduction of …

The onset of dehydration melting of nominally anhydrous peridotite can be calculated by
combination of appropriate mineral/melt partition coefficients for H2O, DHmin/liq, and a …

▪ Abstract The mechanisms of exchange of hydrogen between the deep interior and surface
of Earth, as well as the means of retention and possible abundance of hydrogen deep within …

Olivine, pyroxene and garnet are nominally anhydrous but can accommodate tens to
hundreds of parts per million (ppm) H2O or “water” in the form of protons incorporated in …

Concentrations of OH, and major and trace elements were determined in a suite of mantle-
derived megacrysts that represent the crystallization products of a kimberlite-like magma …

WATER (and hydroxyl, OH) plays an important part in determining the properties of minerals
and melts in the Earth's upper mantle. The main hydroxyl-bearing phases found in rocks …

The crystal structure of natural hydrous rutile from a mantle eclogite nodule has been refined
from single-crystal neutron diffraction data collected at 24 K. The chemical composition was …
