An Ediacaran Metasedimentary Fragment With Northern Gondwana Affinity in the Southern East Kunlun Accretionary Belt, Northern Tibetan Plateau: Implications for the Dispersal of Peri‐Gondwanan Terranes

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Precambrian supercontinent reconstructions largely rely on robust geological constraints. Among these, the basin affinities recorded by Precambrian sedimentary fragments preserved in orogenic belts provide critical evidence for resolving the paleogeographic configurations of microcontinents and continental blocks.

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

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 ...
