The role of discontinuous magma inputs in felsic magma and ore generation

open access: yesOre Geology Reviews, 2007
For a long time, granites have been considered as passive bodies ascending under intrinsic negative density and viscosity contrasts with their host rocks. Chemical variations within a granitic body resulted from in situ differentiation and crystal fractionation.

Heavy Mo–Mg–O Isotopes Anomaly Observed in Orogenic Magmatism: Serpentinites Fingerprint in Paleo‐Oceanic Subduction Zone Magmatism

open access: yesGeophysical Research Letters, Volume 52, Issue 11, 16 June 2025.
Abstract Subducted slabs transport volatiles into the deep mantle, greatly influencing material recycling, earthquakes, and magmatism in subduction zones. However, identifying the nature and amounts of fluids from different sources, including basaltic oceanic crust, sediment, and serpentinite, is difficult.

Constraining Solid Dynamics, Interface Rheology, and Slab Hydration in the Hikurangi Subduction Zone Using 3‐Dimensional Fully Dynamic Models

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 6, June 2025.
Abstract Simulating present‐day solid Earth deformation and volatile cycling requires integrating diverse geophysical data sets and advanced numerical techniques to model complex multiphysics processes at high resolutions. Subduction zone modeling is particularly challenging due to the large geographic extent, localized deformation zones, and the ...

Massive Sulfide Deposition at the 13°30’N Oceanic Core Complex: Lessons Learned From Coupled Hydro‐Thermo‐Mechanical Modeling

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 6, June 2025.
Abstract Young oceanic lithosphere created at mid‐ocean spreading centers is subject to complex magmatic, tectonic and hydrothermal processes, especially in regions of widespread detachment faulting. This study focuses on the oceanic core complex (OCC) at the Mid Atlantic Ridge at 13°30’N. The OCC hosts the active Semenov‐2 vent field and four inactive

Eruption, Emplacement and Internal Architecture of Massive and Super‐Massive Inflated Submarine Basalt Lava Flows, Walvis Ridge Hotspot Track, IODP Expeditions 391/397T

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 6, June 2025.
Abstract Massive submarine basalt flows were sampled at five sites on the Tristan‐Gough‐Walvis hotspot track in the South Atlantic by International Oceanic Discovery Program Expeditions 391/397T, where the plume was interacting with a mid‐ocean ridge, a setting similar to that the of modern Iceland.
