Geology and Chronology of the Lunar Taruntius Crater: Implications for the Retention Age of Lunar Ray Patterns and Lifetime of Lunar Explosive Volcanism

Earth and Space Science, Volume 13, Issue 7, July 2026.
Abstract The Taruntius crater, situated between Maria Fecunditatis, Crisium, and Tranquillitatis, is characterized by a prominent bright ray system and a floor‐fractured morphology and has long been interpreted as a relatively young Eratosthenian or Copernican crater.

Post‐Eruptive Deformation and Faulting Caused by Dike Channel Retraction, Material Drain‐Back and Contraction of the 2021 Tajogaite Craters (La Palma)

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Young scoria cones fed by dike channels or conduits may undergo rapid and substantial post‐eruptive morphological modification; however, the structural controls and mechanisms governing topographic degradation remain poorly constrained. This knowledge gap limits our ability to reliably interpret topography, faults, deposits and the evolution ...

Evolution of Sulfur Concentration in the Deep Earth During the Proto‐Earth Growth: First‐Principles Study on the Sulfur Partitioning Between Metal and Silicate at High Pressure and Temperature

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Sulfur (S) is one of the promising light elements that can explain the density deficit of the core. The degree of siderophile nature of S under high pressure and temperature (P,T) is the key to estimating the S content in the core. However, a significant discrepancy between the metal‐silicate partition coefficient of S extrapolated from ...

Osmium Isotope and Highly Siderophile Element Constraints on the Cretaceous/Paleogene Boundary in Western Pacific Pelagic Clay

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract The Cretaceous/Paleogene (K/Pg) Chicxulub impact produced globally synchronous enrichments of highly siderophile elements (HSEs) and a pronounced decline in marine osmium isotope ratios (187Os/188Os), forming a key geochemical marker of the boundary.

Comparing Piston Flow and Dispersion Models for the Age of Groundwater Collected Through Very Short Screens

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract In previous groundwater dating studies involving samples collected through probes with very short screens, the tracer analysis has assumed the groundwater to have an age range so narrow that it can reasonably be considered a single age (a piston flow interpretation).
