Reconstructing Along‐Strike Variability of Retreating Accretionary Margins Using Detrital Isotopic Proxies in Patagonia and Japan

Tectonics, Volume 45, Issue 9, September 2026.
Abstract Retreating accretionary systems are common features of convergent plate margins. They are characterized by upper plate extension and backarc basin formation, which often forms diachronously and asymmetrically along‐strike. This study tests the hypothesis that this along‐strike variability in backarc basin formation is reflected in detrital and

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.
