Continent-sized anomalous zones with low seismic velocity at the base of Earth's mantle
Seismic images of Earth's interior reveal two massive anomalous zones at the base of the
mantle, above the core, where seismic waves travel slowly. The mantle materials that …

Silica-water superstructure and one-dimensional superionic conduit in Earth's mantle
Water in Earth's deep interior is predicted to be hydroxyl (OH−) stored in nominally
anhydrous minerals, profoundly modulating both structure and dynamics of Earth's mantle …

Stability of hydrous silicate at high pressures and water transport to the deep lower mantle
The presence of water strongly influences the structure, composition and dynamics of the
Earth's deep mantle,,,. Hydrous magnesium-rich silicates play an important role in …

2.16 Seismic anisotropy of the deep Earth from a mineral and rock physics perspective
D Mainprice - Treatise on geophysics, 2010 - books.google.com
In this section the contribution of CPO to seismic anisotropy in the deep Earth with cases of
olivine and the role of melt is illustrated. The CPO in rocks of upper-mantle origin is now well …

The role of hydrogen bonds in hydrous minerals stable at lower mantle pressure conditions
J Tsuchiya, EC Thompson - Progress in Earth and Planetary Science, 2022 - Springer
Over the past few decades, hydrous minerals were thought to be absent in the lower mantle,
due to their instability at high-pressure conditions. Recently, however, hydrous phases …

The pyrite-type high-pressure form of FeOOH
Water transported into Earth's interior by subduction strongly influences dynamics such as
volcanism and plate tectonics,,. Several recent studies have reported hydrous minerals to be …

Stability of a hydrous δ-phase, AlOOH–MgSiO2 (OH) 2, and a mechanism for water transport into the base of lower mantle
The global water cycle in the Earth is one of the most important issues in geodynamics,
because water can affect the physical and rheological properties of the mantle. However, it …

Hydrous minerals and the storage of water in the deep mantle
E Ohtani - Chemical Geology, 2015 - Elsevier
Water is transported into the deep mantle via hydrous minerals in subducting slabs. During
subduction, a series of minerals in these slabs such as serpentine or chlorite, Mg–sursassite …

Dehydrogenation of goethite in Earth's deep lower mantle
The cycling of hydrogen influences the structure, composition, and stratification of Earth's
interior. Our recent discovery of pyrite-structured iron peroxide (designated as the P phase) …

Miscibility of rock and ice in the interiors of water worlds
Abstract Super-Earths and sub-Neptunes are the most common planet types in our galaxy. A
subset of these planets is predicted to be water worlds, bodies that are rich in water and …
