Seismic Exploration for Magmatic Brine Lenses: An Example From Soufrière Hills Volcano, Montserrat
Abstract The majority of metallic ore deposits are related to processes associated with ancient or modern volcanic systems. Beyond geothermal energy production, volcanoes also represent a potential resource of critical metals, including those required for carbon‐neutral technologies. Geothermal metals occur in subsurface fluid reservoirs fed by surface

Competing Effects of Elastic Heterogeneity and Viscous Flow on Interseismic Coupling at Cascadia
Abstract Interseismic coupling maps are important tools for estimating future earthquake hazard at subduction zones. Often interseismic coupling is estimated from surface velocities using a homogeneous elastic Earth model. However, inversions that incorporate viscoelastic mantle flow or elastic heterogeneity show that each can change the spatial ...

Global Evidence for Off‐Axis Flexural Modification of Abyssal Hill Faults at Mid‐Ocean Ridges
Abstract Young oceanic lithosphere flexes as axial topography decays across mid‐ocean ridge shoulders, yet this deformation has been quantified at only a few segments, leaving its global expression poorly constrained. We analyzed 50 across‐axis bathymetric profiles from 21 regions spanning slow to fast spreading rates, identified 1,201 abyssal‐hill ...

Abstract The pattern and cause of upper‐water temperature (UWT) variations on millennial timescales in the Southern Ocean (SO) and the mechanism of their interaction with high‐latitude Northern Hemisphere climate remain unclear. Here, we reconstructed millennial‐scale subsurface temperature (subST) records from the Weddell Sea during the Last Glacial ...

Gravitational Stability of Hydrated SiO2 and Basaltic Crust in the Lower Mantle
Abstract We determined thermal equations of state of hydrated stishovite and CaCl2‐type SiO2 up to 100 GPa and 3,000 K to assess the gravitational stability of hydrated stishovite and basaltic crust in the lower mantle. Using machine‐learning based atomistic simulations, we examined three hydrogen dissolution mechanisms: hydrogarnet‐type, interstitial ...
