Geochronological Constraints on Diachronous Post‐Collisional Slab Breakoff Along the Paleo‐Tethyan Sutures

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.
Abstract The slab breakoff model is a preferred geodynamic interpretation for post‐collisional exhumation and associated magmatic flare‐ups. In this study, rutile U–Pb dating of retrograde eclogites revealed distinct stages of exhumation along the Paleo‐Tethyan sutures in southwest China. The studied samples yielded ages of 246.7 ± 8.5 and 239.7 ± 14.0

Deep Crustal Magma‐Water Interaction During Oceanic Core Complex Termination of the Godzilla Megamullion in the Parece Vela Basin

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.
Abstract Oceanic Core Complexes (OCCs) in back‐arc basins are not as thoroughly investigated, and their termination processes remain poorly understood. The Godzilla Megamullion is the largest known ceased OCC on Earth, yet magmatic and hydrothermal records from its termination are lacking.

Petrogenesis and Tectonic Implication of the Newly Identified Rhyacian and Orosirian Orthogneisses in the Northwestern Part of the Gyeonggi Massif (Soyeonpyeongdo and Ganghwado Areas), South Korea: Constrained From Whole‐Rock Geochemistry and Zircon U‐Pb‐Hf Isotopic Compositions

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.
Abstract The Gyeonggi Massif is one of the major Precambrian basements in the Korean Peninsula where Paleoproterozoic orthogneiss and paragneiss were widely exposed. In this study, newly identified Rhyacian to Orosirian meta‐igneous rocks from the northwestern Gyeonggi Massif (Soyeonpyeongdo and Ganghwado areas) were investigated to elucidate their ...

The Distinction Between Sn‐Mineralized and Sn‐Barren Granites in Sn Isotopes

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.
Abstract Tin mineralization is commonly associated with highly evolved granites. However, not all highly evolved granitic rocks are mineralized with Sn. Comparative studies of Sn‐fertile and Sn‐barren granites can deepen our understanding of the key processes that lead to Sn enrichment in magmatic‐hydrothermal systems.

Building the Andean Crust at ∼35°S: Arc Geochemistry Reveals Cretaceous Thinning and Rapid Neogene Thickening

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Quantification of the timing and mechanisms of crustal thickening in Cordilleran orogenic hinterlands remains challenging. We address this in the Andes using whole‐rock geochemistry and zircon petrochronology from a >70 Myr volcanic record in the Tinguiririca valley of Chile (∼35° ${}^{\circ}$S), which captures a pivotal transition from ...
