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

Quantifying Crustal Thickness in Continental Collisional Belts: Global Perspective and a Geologic Application

Scientific Reports, 2017
We present compiled geochemical data of young (mostly Pliocene-present) intermediate magmatic rocks from continental collisional belts and correlations between their whole-rock Sr/Y and La/Yb ratios and modern crustal thickness. These correlations, which

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 ...

Origins of the Banda Arcs Collisional Orogen and the Banda Sea

Berita Sedimentologi, 2021
Many of the best examples of young arc-continent collision are found in eastern Indonesia, where the northern margin of Australia has been in collision throughout the Neogene with a succession of island arc systems. The Banda Arc is the youngest of these collision zones and forms the present plate boundary in this region.

Collisional orogen dynamics controls the type, timing and location of critical metal deposits

International audienceThe relationship between critical metal mineralizations such as W, Sn, Nb, Ta or Li, and collisional orogeny dynamics remain poorly understood.

Pervasively Thin Anatolian Lithosphere With Elevated Upper Mantle Temperatures in the East: Insights From Bayesian Thermo‐Compositional Inversion

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract Uplift and widespread Late Miocene‐present magmatism in Anatolia are commonly attributed to lithospheric thinning, possibly facilitated by the arrival of hot mantle plume material. There are various lines of evidence for thin present‐day lithosphere, but the spatial extent and degree of lithospheric thinning and the underlying mantle ...

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

Cambrian Stage 3 Paleomagnetism of the South China Block: Implications for Early Paleozoic Gondwana Reconstructions

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract The paleogeographic position of the South China Block (SCB) during the early Paleozoic and its affiliation with Gondwana remain debated. We report new high‐quality paleomagnetic data from sandstone‐dominated Cambrian Stage 3 strata correlated with the Yu'anshan–Hongjingshao succession collected along the southwestern margin of the SCB ...

Looking Under the Orogenic Lid—Assessing the European Basement Beneath the Alpine Wedge by U‐Pb Zircon Geochronology

Tectonics, Volume 45, Issue 10, October 2026.
Abstract Following continental collision, the distal European margin was overridden by the Alpine wedge and is now largely concealed beneath the mostly intact orogenic lid. Consequently, the geological evolution and nature of the hidden basement domains remain poorly constrained.

Anatexis constraints on the post-collisional evolution of the Sulu Orogen, China: evidence from pegmatite veins in migmatite

, 2019
The widespread migmatites in the northwestern part of the Sulu Orogen, China, indicate regional anatexis that is of great significance when discussing the tectonic evolution of this continental orogenic belt.
