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 …

The mantle transition zone, a potential water reservoir in the Earth's interior, is suggested to
contain more than 1 wt.% of H 2 O, at least locally, by the natural water-rich ringwoodite …

Hydrogen may be incorporated into nominally anhydrous minerals including bridgmanite
and post‐perovskite as defects, making the Earth's deep mantle a potentially significant …

Since their introduction in 1929, Pauling's five rules have been used by scientists from many
disciplines to rationalize and predict stable arrangements of atoms and coordination …

Combined synthesis experiments and first‐principles calculations show that MgSiO3‐
perovskite with minor Al or Fe does not incorporate significant OH under lower mantle …

Exoplanets with radii between those of Earth and Neptune have stronger surface gravity
than Earth, and can retain a sizable hydrogen-dominated atmosphere. In contrast to gas …

The presence of water in minerals generally alters their physical properties. Ringwoodite is
the most abundant phase in the lowermost mantle transition zone and can host up to 1.5–2 …

High-pressure silicates making up the main proportion of the earth's interior can incorporate
a significant amount of water in the form of OH defects. Generally, they are charge balanced …

The Tissint meteorite, a picritic shergottite, fell to Earth in Morocco on the 18th of July 2011,
and is only the fifth Martian meteorite witnessed to fall. Hydrogen isotope ratios and water …

Hydrogen site positions and occupancies in the crystal structure of synthetic hydrous
ringwoodite have been determined for the first time by high‐resolution neutron powder …
