Architecture of the Patrimonio Fault System and the Miocene Post‐Orogenic Extension in Alpine Corsica (France)

Tectonics, Volume 45, Issue 8, August 2026.
Abstract The exhumation of Alpine Corsica is the result of Oligocene‐Miocene lithospheric back‐arc extension in the wake of the eastward migration of Apenninic subduction. Although the geometry, kinematics and timing of ductile detachments are well constrained, the brittle extension leading to final exhumation of Alpine Corsica is less documented.

A database of detrital zircon U–Pb geochronology and Hf isotopes from the Songpan–Ganzi and Western Qinling terranes

Geoscience Data Journal
Since the advent of detrital geochronology, significant progress has been made in the study of sedimentary sources. The detrital zircon U–Pb age spectrum, especially when combined with zircon Hf isotopes, provides a powerful tool for determining the ...

Early–Late Carboniferous Tectonic Evolution of the Northern North China Craton (NE China): Constraints From Zircon Ages, Geochemistry, and Crustal Thickness Modeling

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract The tectonic evolution of the northern margin of the North China Craton (NCC) remains controversial. In this study, we obtained zircon U–Pb ages, geochemical data, and Sr–Nd isotopic data for volcanic rocks, and detrital zircon ages for sedimentary rocks from the Yufutun, Tongqigou, and Benxi formations in central‐southern Jilin Province, NE ...

Geochemistry, Sm-Nd isotopes and SHRIMP U-Pb geochronology of the Morro do Coco Granite (RJ, Brazil): another piece of the post-collisional magmatism of the Ribeira Belt

Brazilian Journal of Geology
The Morro do Coco granite (MC) is a post-collisional intrusive body that was emplaced at Ribeira Belt, in the Cambro-Ordovician, succeeding the final stages of the Gondwana supercontinent amalgamation.

Two Distinct Growth Styles of Riedel Shear Zones in Cratonic Strike‐Slip Fault System, Tarim Basin, NW China

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract The kinematics and progressive evolution of Riedel shear zones have been extensively studied, yet the factors controlling their distinct evolutionary styles in natural settings remain debated. Understanding such fracture network architecture has great implications, such as predicting subsurface fluid flow and assessing seismic hazards.

Post‐Collisional Evolution in the Southern Variscan Belt: Insights From Numerical Modeling of the Valpelline Series (Western Alps)

Tectonics, Volume 45, Issue 8, August 2026.
Abstract The post‐collisional evolution of orogenic belts is commonly marked by high‐temperature metamorphism and widespread magmatism, yet the processes linking collision to post‐collisional dynamics remain difficult to reconstruct due to limited exposure of deep‐crustal levels and uncertainties in the determination of pressure‐temperature conditions ...

Exhumation History of the Sangre de Cristo Range, Colorado, From Mid‐ to Low‐Temperature Thermochronology: New Insights Into Laramide Contraction and Oligocene–Miocene Extension in the Northern Rio Grande Rift, USA

Tectonics, Volume 45, Issue 8, August 2026.
Abstract The Sangre de Cristo Range in southern Colorado records a complex tectonic history that includes Late Cretaceous–Eocene Laramide contraction and Oligocene–Quaternary Rio Grande rift extension. We present new thermochronologic data (40Ar/39Ar, fission‐track, (U‐Th)/He) and thermal history models that provide insight into this polyphase history ...

Ediacaran–Cambrian High‐Strain Melt‐Present Deformation of the Archean Charcot Province, East Antarctica

Tectonics, Volume 45, Issue 8, August 2026.
Abstract The assembly of Gondwana involved several Pan‐African orogens, although their extension into ice‐covered Antarctica remains contentious. Particularly problematic is our understanding of the Kuunga orogenic system in East Antarctica, including its eroded architecture and temporal evolution. The remote Charcot Province, at the easternmost extent
