Key New Evidence for the Hainan Mantle Plume Head: Ongoing Formation of a Large Igneous Province?
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.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.

Impulsive supply of volatile-rich magmas in the shallow plumbing system of Mt. Etna volcano [PDF]
, 2018 Magma dynamics at Mt. Etna volcano are frequently recognized as the result of complex crystallization regimes that, at shallow crustal levels, unexpectedly change from H2O -undersaturated to H2O-saturated conditions, due to the impulsive and irregular ...

Combined Gravimetric-Seismic Moho Model of Tibet
Geosciences, 2018 Substantial progress has been achieved over the last four decades to better understand a deep structure in the Himalayas and Tibet. Nevertheless, the remoteness of this part of the world still considerably limits the use of seismic data.

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.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.

Convergent flow in a two-layer system and mountain building [PDF]
, 2010 With the purpose of modelling the process of mountain building, we investigate the evolution of the ridge produced by the convergent motion of a system consisting of two layers of liquids that differ in density and viscosity to simulate the crust and the

La Granja, 2013 Como requisito previo para la consecución de imágenes tomográficas se estudian tres modelos de Moho. Para la región de Ecuador se analizan el modelo gravimétrico de Chambat-Valette, un modelo de velocidades de propagación de ondas sísmicas en tres dimensiones y un modelo de observaciones gravimétricas satelitales.

Autocorrelation Seismic Imaging of Northern Taiwan Using Ambient Noise Data
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.Abstract Over the past few million years, northern Taiwan records a tectonic history of subduction to arc–continent collision followed by post‐collisional collapse. This evolution motivates constraints on crustal structure, including crustal layering and thickness.

Harry Hess and sea-floor spreading [PDF]
, 1999 Harry Hess's hypothesis of sea-floor spreading brought together his long-standing interests in island arcs, oceanic topography, and the oceanic crust. The one unique feature of Hess's hypothesis was the origin of the oceanic crust as a hydration rind on ...

Earth and Space Science, 2023 The Moho is the interface between crust and mantle, and accurate location of the Moho is important for both resource exploration and deep earth condition and structural change investigations. The theory of the traditional Parker‐Oldenburg (P‐O) method is

Lateral Variations in Lunar Crustal Thickness Inferred From Apollo Seismic and GRAIL Gravity Data
Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.Abstract The internal structure of the Moon is key to understanding its formation, evolution, and bulk composition. In particular, determining the structure of the crust–mantle interface (Moho), including its lateral variations, is of significant importance, but current knowledge is still insufficient to fully constrain it.
