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

open access: yesGeochemistry, 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 ...

An Open‐Source Markov Chain Monte Carlo Inversion Software for the Analysis of Experimental Rock Deformation Data

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract Despite its importance in modeling the interior dynamics of a planet, our understanding of interior rheology remains incomplete because of several reasons, including insufficient experimental data and inadequate analysis of the available data.

Highly Enriched and Heterogeneous Mantle Signals Recorded in Mantle Pyroxenite Veins

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract The Earth's mantle is inherently heterogeneous, reflecting ongoing mantle depletion and crustal recycling driven by plate tectonics. Radiogenic isotopes in oceanic basalts are commonly used to characterize mantle reservoirs, but the full chemical diversity of mantle‐derived melts may be obscured by magma mixing during melt transport and ...

Distinct Transcrustal Evolutions of Komatiitic Primitive Magma: Implications for the Compositional Dichotomy of Continental Flood Basalts

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract The origin of the compositional dichotomy between high‐Ti and low‐Ti basalts in continental flood basalt provinces remains debated. Most existing studies attribute this dichotomy directly to variations in primitive magma composition to circumvent the complexities of significant evolutionary processes, such as multiphase fractional ...

Seafloor Displacements Across the Mid‐Ocean Ridge Eruption Cycle Modulated by Mush Zone Viscosity

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Mid‐ocean ridges (MORs) are active volcanic systems where axial magma lenses (AMLs) are replenished on decadal time scales, enabling frequent dike intrusions. The associated seafloor deformation, however, remains scarcely understood. Here we assess this deformation by simulating cycles of steady AML inflation followed by instantaneous dike ...
