Hydrothermal Manganese‐Oxide Mineralization of a Carbonate Ooze, Samoan Hotspot Region, South Pacific Ocean

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract Low‐temperature hydrothermal manganese oxides occur throughout the global oceans. However, the hydrothermal replacement of a carbonate ooze by manganese oxides is described here for the first time. The 24 samples dredged from three locations around the Territory of American Samoa in the South Pacific Ocean include six samples with remnant ...

Tracing the Persistence and Role of Deep‐Sea Iron Sources in the Pacific Ocean Over the Last 23 Million Years

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Iron (Fe) plays a critical role in marine productivity and the global carbon cycle. The relative contribution of different Fe sources such as atmospheric aerosols, sediment dissolution, and submarine hydrothermalism influences the distribution and biogeochemical cycling of Fe in the ocean. However, distinguishing these Fe sources over time has

Fe–Mn Crust δ98Mo Decline Records Tectonic Forcing on Marine Oxide Sink Reduction During the Early Eocene–Early Oligocene

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract S, Tl, and W isotope records document pronounced early Eocene shifts in marine redox, yet the absence of a Mo isotope record obscures its progression. Here, we present ∼80 Myr Mo–Os–Be–Nd isotope profiles from a Northwest Pacific hydrogenetic Fe–Mn crust, revealing a systematic δ98Mo decline from −0.24‰ (early Eocene) to −0.83‰ (early ...

Rethinking Seawater Mo Isotope Mass‐Balance and the Sedimentary Mo Record

Paleoceanography and Paleoclimatology, Volume 41, Issue 3, March 2026.
Abstract A lingering misconception is that seawater 98Mo/95Mo ratios should have increased more or less linearly with the oxygenation of Earth's oceans. At the root of this hypothesis is the generalization that oxidizing marine sediments have a stronger affinity for lighter‐mass Mo isotopes than their reducing counterparts.
