Geophysical observations suggest that the transition zone is wet locally. Continental and
oceanic sediment components together with the basaltic and peridotitic components might …

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 …

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 …

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 …

At ambient pressure, the hydrogen bond in materials such as ice, hydrates, and hydrous
minerals that compose the Earth and icy planets generally takes an asymmetric OH··· O …

First principles calculations have shown that the high‐pressure phase transition of phase D
MgSi2O6H2 to the new high‐pressure hydrous phase MgSiO4H2 plus stishovite occurs at …

The compression behaviors of δ-AlOOH and δ-AlOOD were investigated under quasi-
hydrostatic conditions at pressures up to 63.5 and 34.9 GPa, respectively, using results from …

Constraining the accommodation, distribution, and circulation of hydrogen in the Earth's
interior is vital to our broader understanding of the deep Earth due to the significant …

We examined the volume compression and phase transformations of H 2 O ice by a
combination of synchrotron x-ray diffraction measurements and density-functional …

Serpentines occur in the subduction zone settings, both along the slab and within the mantle
wedge, they are candidates for transporting water in to the deep earth. Their presence is …
