Calcium Solubility of Bridgmanite in Subducted Basalt in Earth's Lower Mantle

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The calcium solubility in bridgmanite and the resulting abundance of davemaoite under lower‐mantle pressure‐temperature conditions have been under debate following a recent report of extensive calcium dissolution in bridgmanite. We experimentally investigated the calcium solubility in bridgmanite in a basaltic composition at pressures up to ...

Atomic Simulations of Volatile Coverage on Silicate Surfaces

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Understanding how surface processes shape exosphere formation on airless bodies is limited by how surface properties influence the ejection of volatiles such as Na. Recent studies show that retention and release are sensitive to surface binding energy (SBE), motivating the need for SBE values as a function of mineral type and surface coverage.

Exsolution, Evolution, and Hysteresis of CO2 Nanobubbles in Water‐Saturated Sandstone

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Understanding CO2 nanobubble formation in water‐saturated sandstone is critical for understanding fluid behavior in CO2 storage systems. Here, CO2 exsolution from an aqueous phase in a sandstone was investigated using small‐angle neutron scattering at 50°C during cyclic depressurization from 12 to 0.7 MPa.
