Evolution of the Source Mineralogy and Lithospheric Controls on Magmatism During the Northeast Atlantic Continental Breakup

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 2, February 2026.
Abstract The mid‐Norwegian Margin, part of the North Atlantic Igneous Province (NAIP), is a well‐studied volcanic rifted margin formed during the breakup between Greenland and Eurasia ∼56 Ma, with the largest accumulation of magmatic material hosted by the Vøring Margin section.

Silicate and Carbonate Weathering Perturbation at the Eocene‐Oligocene Transition Recorded by Mg Isotopes

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 2, February 2026.
Abstract During the Eocene‐Oligocene Transition (ca. 34 Ma), the Earth underwent a dramatic decline in atmospheric CO2, global cooling, a deepening of the carbonate compensation depth (CCD), and the formation of a permanent ice sheet on Antarctica. The expansion of Antarctic glaciers eroded the underlying bedrock and increased the weathering flux to ...

Iron–Phosphorus–Carbon Coupled Cycling in Lacustrine System of Ordos Basin During the Middle Triassic

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 2, February 2026.
Abstract Widespread organic‐rich shales are associated with perturbations in productivity or preservation conditions; however, the major controlling factors, especially the phosphorus (P) and iron (Fe) interactions and their impacts on organic carbon burial in the paleolake ecosystem remain poorly understood.

Assessing Pb Isotopic Equilibrium Between Apatite and K‐Feldspar

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 2, February 2026.
Abstract Quantifying common Pb, the non‐radiogenic Pb present in a mineral independent of in situ U decay, is essential for obtaining accurate U–Pb ages in common Pb‐bearing minerals such as apatite. However, constraining the amount and composition of common Pb, as well as the timing of its entrapment, remains a persistent challenge.

Diagenetic and Hydrothermal Processes Produce Heavy Molybdenum Isotope Signatures in Pelagic Sediments of the North and South Pacific

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 2, February 2026.
Abstract Molybdenum isotopes (δ98Mo) have been used for more than two decades to investigate past‐ocean redox conditions due to the distinct behavior of this element in oxic and anoxic environments. The oxic sink is generally accepted to have a near‐constant δ98Mo value of −0.7‰, a value derived primarily from the δ98Mo signatures of Fe–Mn crusts and ...

Slab‐Mantle Interaction During Subduction Initiation: Constraints From Trace Element and Sr‐Nd‐Pb Isotope Systematics of Boninite and Other Magmas and Metamorphic Sole in the Oman Ophiolite

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract The Late Cretaceous Oman ophiolite includes a series of volcanic rocks generated during the transition from spreading ridge to protoarc associated with subduction initiation. We analyzed major and trace elements and Sr, Nd, and Pb isotope compositions of lavas and dikes of the protoarc stage, especially boninites. We also analyzed amphibolites
