Removal of dissolved organic carbon in the West Pacific hadal zones

Deep-sea dissolved organic carbon is significantly removed within hadal trenches, positioning these regions as critical sinks in the global DOC pool and highlighting a potential coupling between the marine carbon cycle and tectonic activity.

Earthquake-enhanced dissolved carbon cycles in ultra-deep ocean sediments

Earthquakes enhance dissolved carbon production and fuel the microbial activities in hadal trench subsurface sediments, and ultimately strengthen carbon accumulation and transformation in the subduction zones.

U redox state tracked in mineralized hydrothermal carbonate with implications for U-Pb geochronology

In situ U-Pb carbonate geochronology is robust under hydrothermal conditions and, combined with X-ray absorption spectroscopy techniques, can track the temporal evolution of redox changes and boiling processes critical to metal deposition in multistage hydrothermal-magmatic ore deposits.

Subglacial precipitates record Antarctic ice sheet response to late Pleistocene millennial climate cycles

Piccione et al find evidence for Antarctic ice sheet instability driven by millennial cycles in Southern Ocean temperature, providing clues for the mechanisms that link climate change and rapid Antarctic ice loss events.

Coupled influence of tectonics, climate, and surface processes on landscape evolution in southwestern North America

Cenozoic landscape evolution of southwestern North America remains debated. Here, the authors reconstruct landscape using 4-D numerical models, which can explain extensional collapse and superficial geological record for the Basin and Range Province

The role of gravitational body forces in the development of metamorphic core complexes

A long-standing controversy surrounds low-angle nature of observed detachment faults within metamorphic core complexes. Here, the authors show that post-orogenic collapse of mountain belts can create a low-angle detachment, resolving the controversy.

Recycling of subducted crustal components into carbonatite melts revealed by boron isotopes

The origin of carbon-rich magmas is unclear. Boron isotopic analysis of carbonatite magmas that formed over the past 2.6 billion years reveals a link to carbon recycled during tectonic plate subduction.

Deep anoxic aquifers could act as sinks for uranium through microbial-assisted mineral trapping

Reduction of geochemically mobile hexavalent uranium in deep anoxic aquifers is facilitated by bacteria-driven degradation of organic material and accumulation in calcite and iron-sulfides, according to observations and experiments from a borehole at Äspö, Sweden.
