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 …

Understanding the concentration and distribution of water in the Earth's mantle plays a
substantial role in studying its chemical, physical and dynamic processes. After a decade of …

The hydrogen-isotope [deuterium/hydrogen (D/H)] ratio of Earth can be used to constrain the
origin of its water. However, the most accessible reservoir, Earth's oceans, may no longer …

Hydrogen and deuterium isotopic evidence indicates that the source of terrestrial water was
mostly meteorites, with additional influx from nebula gas during accretion. There are two …

High‐quality single‐crystals of (Al, Fe)‐bearing bridgmanite, Mg0. 88 Fe3+ 0.065 Fe2+
0.035 Al0. 14Si0. 90O3, of hundreds of micrometer size were synthesized at 24 GPa and …

Water solubility in the dominant lower-mantle bridgmanite phase remains controversial.
Discrepancies between previous results highlight the importance of the growth high-quality …

Oceans on Earth are present as a result of dynamic equilibrium between degassing and
regassing through the interaction with Earth's interior. We review mineral physics …

Hydrogen is an important light element in the Earth's core for its high cosmochemical
abundance and strong affinity to iron under core-formation conditions. Thus, constraining the …

Sub-Neptunes are common among the discovered exoplanets. However, lack of knowledge
on the state of matter in H 2 O-rich setting at high pressures and temperatures (P− T) places …

In this study, we report the first direct evidence for water-bearing fluids in the uppermost
lower mantle from natural ferropericlase crystal contained within a diamond from São Luíz …
