Abstract Magmatic underplating beneath the Hawaiian Ridge has been inferred from early active‐source and teleseismic studies, whereas more recent active‐source seismic imaging and reprocessed legacy data have not identified a distinct underplated layer.

Abstract The bathymetry of marginal sea basins commonly deviates from depths calculated by classical lithospheric cooling models, yet the controlling mechanisms remain debated. Here, using 19 seismic profiles and corrected local heat‐flow data, we apply an improved half‐space cooling model within a two‐stage reconstruction to reassess thermal ...

Thermo‐Mechanical Controls on Central‐Vent Caldera Collapse
Abstract Large‐scale magmatic systems are associated with catastrophic caldera‐forming eruptions, posing hazards to millions near active volcanoes. Despite occurring across a range of sizes, the physics driving caldera collapse remain incompletely understood. While large calderas have received considerable attention, moderately sized calderas (∼5–10 km)

Tracking Deep Mantle Melting on Mars Using Phobos Tides
Abstract We study the deep internal structure and rheological state of Mars by analyzing its response to tidal forces exerted by Phobos and by introducing a melt fraction in the mantle layers. Motivated by recent seismic evidence for a basal molten layer near the base of the Martian mantle, we explore the distribution of melt within the mantle and its ...

Brine Entrainment During Ice Shell Growth on Icy Worlds
Abstract The role of ocean composition in governing ice shell growth and ocean longevity on icy satellites remains poorly constrained. To address this, we develop a thermomechanical model of small to mid‐sized icy worlds that simulates ice shell growth from a saline ocean, explicitly quantifying brine entrainment through a parameterization of reactive ...
