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 …

Water‐Induced Mantle Overturns Leading to the Origins of Archean Continents and Subcontinental Lithospheric Mantle

Z Wu, J Song, G Zhao, Z Pan - Geophysical Research Letters, 2023 - Wiley Online Library

important events in the early Earth. The mechanisms for the origins of Archean continents …

Mixed incorporation of carbon and hydrogen in silicate melts under varying pressure and redox conditions

BB Karki, DB Ghosh, D Banjara - Earth and Planetary Science Letters, 2020 - Elsevier
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 …
