Evidence for Miocene subduction beneath the Alboran Sea (Western Mediterranean) from 40Ar/39Ar age dating and the geochemistry of volcanic rocks from holes 977A and 978A [PDF]
, 1999 Volcanic pebbles in gravels from Sites 977 and 978 in the Alboran Sea (western Mediterranean) were dated (using the 40Ar/ 39Ar single-crystal laser technique) and analyzed for their major- and trace-element compositions (determined by X-ray ...

Reconnaissance study of watershed and cave sediment sources discharging from a karst spring, Iowa
Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.Abstract Springs discharging from karst landscapes provide sustainable flows to natural ecosystems and support productive fish hatcheries but sediment discharging from springs threatens the long‐term sustainability of hatcheries. In this study, we conducted a reconnaissance study to evaluate watershed and cave sediment sources discharging to Siewers ...

The zirconium isotope geochemistry of the Earth's mantle and crust
La géochimie isotopique du zirconium dans le manteau et la croûte de la terre La Terre est la seule planète terrestre à présenter une tectonique des plaques, bien que la date de son déclenchement fasse encore l'objet de débats animés. La production de la croûte continentale felsique est généralement considérée comme un indicateur de l ...

Gravitational Stability of Hydrated SiO2 and Basaltic Crust in the Lower Mantle
Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.Abstract We determined thermal equations of state of hydrated stishovite and CaCl2‐type SiO2 up to 100 GPa and 3,000 K to assess the gravitational stability of hydrated stishovite and basaltic crust in the lower mantle. Using machine‐learning based atomistic simulations, we examined three hydrogen dissolution mechanisms: hydrogarnet‐type, interstitial ...

Tracing Continental Basalt Sources and Mantle Processes Using Fe Stable Isotopes
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.Abstract Iron (Fe) isotopes have emerged as powerful tracers of mantle source heterogeneity and melting processes, yet the mechanisms producing heavy Fe isotope signatures (high δ57Fe values) in intraplate basalts remain debated. Competing interpretations include partial melting of recycled pyroxenite domains versus carbonate‐induced oxidation of a ...
