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 …

Plate tectonics: the stabilizer of earth's habitability
Earth is the only planet known to be habitable, and is also unique with its liquid water, and
the operation of plate tectonics. The geological record shows that the habitability of our …

Large‐scale atomistic simulations of magnesium oxide exsolution driven by machine learning potentials: Implications for the early geodynamo
J Deng - Geophysical Research Letters, 2024 - Wiley Online Library
The precipitation of magnesium oxide (MgO) from the Earth's core has been proposed as a
potential energy source to power the geodynamo prior to the inner core solidification. Yet …

Mixed incorporation of carbon and hydrogen in silicate melts under varying pressure and redox conditions
Volatiles including carbon and hydrogen are generally considered to be more soluble in
silicate melts than in mantle rocks. How these melts contribute to the storage and distribution …

Volatile and trace element storage in a crystallizing martian magma ocean
Immediately following core formation on Mars, the planet underwent a magma ocean phase.
Volatiles released from the magma ocean fostered a primitive atmosphere which modulated …

Behavior and properties of water in silicate melts under deep mantle conditions
Water (H2O) as one of the most abundant fluids present in Earth plays crucial role in the
generation and transport of magmas in the interior. Though hydrous silicate melts have been …

Identifying dehydration-induced shear velocity anomaly in the Earth's core-mantle boundary
The steep temperature gradient near the bottom of the mantle is known to generate a
negative correlation between the shear wave velocity (VS) and the depth in most regions of …
