Geochemical and Isotopic Constraints on Long‐Lived Source Enrichment and Mantle Evolution in Paleoproterozoic Cratonic Lamprophyres

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract The cratonic lithospheric mantle records complex metasomatic processes and is frequently tapped by alkaline magmatism, offering a unique opportunity to trace the progressive evolution of the mantle. In the present contribution, we investigate a newly identified calc‐alkaline lamprophyre field from the Neoarchean Jonnagiri Schist Belt, Eastern ...

Standardized Frameworks for n‐Alkane Compound‐Specific Isotope Analysis: Assessments and Analytical Platform for Data Processing Workflows and Uncertainty Estimation

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Post‐acquisition processing of plant wax n‐alkane isotope data in compound‐specific isotope analysis (CSIA) remains variable and often lacks transparency. To improve inter‐laboratory comparability and data reliability, we present standardized, reproducible workflows for CSIA that address key challenges in drift correction, scale normalization,

Rift Development, Tectonic Forcings, and Magmatic Feedbacks at Santorini and Kolumbo Volcanoes Constrained by Scientific Drilling and Core‐Seismic Integration

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Volcanism in continental rifts, rifted volcanic arcs, and back‐arc basins is fundamentally coupled with crustal extension. However, the precise geometry and timing of the fault systems that facilitate magma transport and accommodate extension remain poorly constrained.

Height‐Dependent Evolution of the Ionospheric Response to the May 2024 Superstorm: Global GNSS‐POD, GNSS‐RO, and Ground‐Based Observations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract Capturing global ionospheric response during extreme geomagnetic storms remains a major observational challenge. During 10–11 May, 2024 superstorm, we investigate the height‐dependent response of the F‐region using multi‐constellation GNSS‐POD limb‐sounding measurements from COSMIC‐2, Spire, PlanetiQ, and FengYun‐3 satellites. Approximately 12,

Ionosphere‐Thermosphere Responses to the March 2023 Geomagnetic Storm Using Observations and TIEGCM Simulations Driven by Data Assimilated Aurora and Electric Fields

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract We investigate Ionosphere‐Thermosphere (IT) responses to the March 2023 geomagnetic storm using GOLD and PFISR observations, along with TIEGCM simulations driven by data‐assimilated aurora and electric fields. A Lattice Kriging approach is implemented to assimilate auroral electron flux and characteristic energy from ground‐based (THEMIS/ASIs)
