From oceanic subduction to continental collision: An overview of HP-UHP metamorphic rocks in the North Qaidam UHP belt, NW China

, 2016
The North Qaidam UHPM belt is unique among " continental type" subduction zones in showing well-preserved subducted oceanic relics that predate continental subduction and collision.

Position of the Lhasa Terrane and Two‐Stage Crustal Shortening During the India–Asia Collision

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract The paleolatitudinal change of the Lhasa Terrane is critical for estimating the timing of the India–Asia collision and associated syn‐to post‐collisional crustal shortening, but its paleoposition is highly debated. Here we present integrated geochronologic and paleomagnetic results from the Lower Eocene Nianbo Formation in the Linzhou Basin ...

Tracing the Syn‐Convergence Extrusion Tectonics of the Sulu Orogenic Belt and Its Implication for North China–South China Collision

Geochemistry, Geophysics, Geosystems
Understanding the transition from oceanic to continental subduction is critical for reconstructing the geodynamic evolution of orogens and constraining ancient plate boundaries.

State of Stress in Subduction Zone Forearcs: Influence of the Mantle Wedge Corner and Serpentinization

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract We investigate the role of the elasticity and density of the forearc mantle wedge corner on the stress distribution in the forearc region of subduction zones, using numerical quasi‐2D lithospheric deformation models for the Cascadia, Nankai, NE Japan, and Costa Rica subduction zones. We incorporate the forearc mantle wedge corner as an elastic

In Situ Observation of Pressure‐Enhanced Hydrous–Anhydrous Solid Solution in Lower‐Mantle SiO2–AlOOH Phases

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Water plays a critical role in Earth's mantle dynamics and evolution, yet lower‐mantle storage mechanisms remain debated. δ‐AlOOH and SiO2 phases have been independently proposed as high‐pressure water hosts. Here, we conducted in situ synchrotron X‐ray diffraction experiments with a multi‐anvil apparatus and sintered diamond anvils to ...

Subduction

, 1994
This book is devoted to the quantitative physical modeling of subduction and subduction-related processes. It presents a coherent description of the modeling method (including similarity criteria, and a novel applied experimental technique), results from

Fractal Analysis, Morpho‐Sedimentary Aspects and Coastal Vulnerability in Mediterranean Islands: A Novel Approach

Earth Surface Processes and Landforms, Volume 51, Issue 10, October 2026.
An integrated framework combining fractal geometry, sedimentology and coastal exposure analysis revealed higher coastal vulnerability in Procida than in Mykonos despite the latter's greater shoreline complexity. This approach provides a robust tool for assessing morphodynamics and supporting sustainable management of Mediterranean island coasts ...

Geodynamic modeling on continental collision in Qilian orogenic belt

Frontiers in Earth Science
The Qilian orogenic belt (QOB) located in the northeast margin of the Tibetan Plateau is featured by remarkable crustal thrusting and shortening, providing a key natural example to understand the lithospheric deformation of the Tibetan Plateau. Two types

Geodynamic Significance of Intraplate Basaltic Magmatism From the Western Mediterranean Region

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Dynamic topography changes as mantle convection evolves, making its past surface expression difficult to reconstruct. Widespread Neogene‐Quaternary intraplate basaltic magmatism across the Western Mediterranean Region allows us to test whether dated basalts preserve the mantle thermal structure responsible for regional dynamic support.

Saline fluids play a major role in continental crust formation

Frontiers in Earth Science
A new general perspective on the long-standing problem of continental crust formation is presented in this study. Unlike prevailing models for continental crust formation that rely heavily on the behavior of major and trace elements in silicate melts in ...
