Subduction Recycling and Closure of the Paleo‐Asian Ocean in the Beishan Orogen: Constraints From the Niujuanzi Ophiolitic Mélange and Associated Intrusions

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Ophiolitic mélanges and associated intrusions provide key archives for reconstructing the evolution of ancient ocean basins and subduction‐related mantle modification. The Hongliuhe–Niujuanzi–Xichangjing ophiolitic mélange in the central Beishan Orogen preserves important records of the Paleo‐Asian Ocean, but the timing of oceanic subduction ...

Restoring the Missing Late Cretaceous Arc of Iran

Geochemistry, Geophysics, Geosystems
Persistent arc magmatism archives fluid transport and mantle partial melting in subduction zones. However, arc magmatism often exhibits different magmatic records along the strike, as seen in the Tethyan orogenic belt.

An Ediacaran Metasedimentary Fragment With Northern Gondwana Affinity in the Southern East Kunlun Accretionary Belt, Northern Tibetan Plateau: Implications for the Dispersal of Peri‐Gondwanan Terranes

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Precambrian supercontinent reconstructions largely rely on robust geological constraints. Among these, the basin affinities recorded by Precambrian sedimentary fragments preserved in orogenic belts provide critical evidence for resolving the paleogeographic configurations of microcontinents and continental blocks.

Spatial and temporal radiogenic isotopic trends of magmatism in Cordilleran orogens [PDF]

Gondwana Research, 2017
Abstract An intrinsic feature of Cordillera-style orogenic systems is a spatial trend in the radiogenic isotopic composition of subduction-related magmatism. Magmatism is most isotopically juvenile near the trench and becomes increasingly evolved landward. A compilation of radiogenic isotopic data from the central Andes, U.S.

The Wilson Cycle of the North Altyn Ocean: A Record of Subduction Initiation, Slab Rollback, and Final Closure

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract The North Altyn ophiolitic belt was formed by the subduction–closure of the Altyn segment of the Proto–Tethys Ocean and recorded the accretion of Tarim to northern Gondwana, but the timing of initial subduction and detailed tectonic transition processes remain poorly constrained. This study reports the oldest Phanerozoic magmatic record of 537

Gold Source and Deportment in the Daqiao Epizonal Orogenic Gold Deposit, China [PDF]

, 2019
Yafei Wu’s PhD project has explored different ore-forming aspects of a world-class Chinese orogenic gold deposit. The results show that orogenic gold could be sourced from either metamorphism or magmatism.

Role of Post‐Collisional Magmatism in Continental Growth and Reworking Since the Late Archean

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract The mechanisms responsible for the formation and compositional evolution of continental crust remain central questions in Earth science. Post‐collisional magmatism is widely preserved in the continental record; however, its contribution to crustal growth may be underestimated because enriched isotopic signatures obscure juvenile mantle input ...

The Role of Slab Folding in Modulating the Landscape Evolution of Ribbon Collision

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract We investigate how slab folding impacts the topographic evolution of collisional orogens and the sediment supply to the associated basins, under the effect of different erosion and sedimentation rates. Results show that when slab folding causes the steepening of the subducting slab, it enhances topographic growth in the orogen at rates between
