Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.Abstract After assembly, supercontinents are shaped by internal rifting and peripheral subduction. However, the geodynamic relationship between these two processes and their respective contributions to supercontinent breakup remain poorly understood.

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.Abstract Granitoid magmatism along the western Pacific margin records interactions between subduction dynamics and crust–mantle processes; however, the links between plate reorganization and magma‐source evolution remain debated. Here we integrate U–Pb zircon geochronology with Pb–Sr–Nd–Hf isotope systematics to investigate Cretaceous–Paleogene ...

Geochemistry of peridotites, gabbros and trondhjemites of the Ballantrae complex, SW Scotland
, 1984 Major and trace element, including REE, analytical data are used as bases for interpreting the petrogenesis of the major igneous components of the northern part of the Ballantrae complex which occurs in the southwestern part of the Midland Valley of ...

Journal of Metamorphic Geology, Volume 44, Issue 4, Page 265-286, May 2026.ABSTRACT The Quetico subprovince of the Superior Province is among the largest metasedimentary belts globally and provides evidence of tectonic processes at play during the final stages of Archean cratonization. Although previous studies have shown that deformation and metamorphism of the 2.7‐Ga turbiditic protolith resulted in regional subvertical ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.Abstract Widespread mafic magmatism at ca. 1.8–1.7 Ga across fragments of the Columbia supercontinent records a transition in the Earth's supercontinent cycle. The paleogeographic position of the Dunhuang Block in northwestern China within Columbia, and its role in this tectonic reorganization, remain controversial.

Tectonics, Volume 45, Issue 4, April 2026.Abstract Our understanding of subduction initiation remains limited by the difficulty of making direct observations of geologically recent examples. In the geologic record, supra‐subduction zone ophiolites are often interpreted to record syn‐initiation slab rollback and upper plate extension. Unfortunately, many ophiolites are decoupled from records of
