Influence of Inherited Rifted Margin Architecture on Continental Collision Dynamics
Abstract Continental collision is a key process in lithospheric evolution, driving mountain building, crustal thickening, and supercontinent assembly. Within the Wilson cycle, collision marks the final stage following rifting, ocean spreading, and subduction.

Hunga‐Tonga Volcano Plumbing System Inferred From Virtual Seismometer Approach
Abstract We present a surface wave tomography application based on event‐pair interferometry to investigate local (∼100 km) mid‐ocean crustal structures, with a particular focus on imaging a potential crustal solidified intrusive complex in a region lacking seismic stations.

Abstract In subduction zones, the locked seismogenic zone is bordered by an upper and a lower transition zone. In these transition zones, deformation is primarily accommodated by an interplay of diffuse viscous deformation within a weak matrix and brittle deformation in stiffer bands and blocks.

Flux and Isotopic Composition of Sedimentary Carbon Subducting Along the World's Trenches
Abstract Here we provide comprehensive estimates for the subducted sedimentary flux of inorganic and organic carbon and δ13C at 16 trench segments worldwide. Our calculations provide minimum (incoming sediment), maximum (trench fill) and best estimates (underthrust) of carbon fluxes.

Seismic Constraints on the 3‐D Magma Conduit System of Mount Etna
Abstract Mount Etna, one of the most active volcanoes in the world, provides an excellent natural laboratory for investigating magma plumbing systems. However, previous models of Etna's volcanic structure have not adequately resolved the distribution of deep magma conduits. In this work, we use seismic tomography to obtain high‐resolution 3‐D images of

Key New Evidence for the Hainan Mantle Plume Head: Ongoing Formation of a Large Igneous Province?
Abstract The process‐based surface magmatic expression of mantle plumes is typically a large igneous province (LIP) induced by the mantle plume head, followed by subsequent age‐progressive volcanic tracks resulting from plate drifting above the plume tail.

Hornblendite in the Lower Crust: A Possible Source for Porphyry Cu Deposits
Abstract Lower crustal sulfide‐bearing Cu‐rich cumulates, mainly occurring as hornblendite, have been proposed as a critical source component for the development of giant porphyry Cu deposits (PCDs); however, their mineralogical and geochemical nature remain elusive.

Abstract The Blanco transform fault system (BTFS) represents an evolving transform plate boundary in the Northeast Pacific Ocean. Its seismic behavior was captured with a dense network of 54 ocean‐bottom seismometers (OBS) operated for 1 year. We created a high‐resolution earthquake catalog based on different machine‐learning onset pickers.
