Ammonium-Enhanced Arsenic Mobilization from Aquifer Sediments

Ammonium-related pathways are important for groundwater arsenic (As) enrichment, especially via microbial Fe(III) reduction coupled with anaerobic ammonium oxidation

Marine Aluminum Phosphate–Sulfate Authigenesis as a Phosphorus Sink During Mid-Proterozoic Oxygenation

Enhanced continental phosphorus input into the ocean has been suggested as a potential trigger for the transient oxygenation events during the mid-Proterozoic; however, the response of phosphorus cycling to these marine oxygenations remains unclear.

Cretaceous magmatism in the northern Lhasa Terrane: Implications for the tectonic evolution and crustal growth tempos of central Tibet

The subduction and demise of an ocean plate are generally recognized as essential processes that result in the reworking and maturation of the continental crust.

Large Igneous Province Emplacement Triggered an Oxygenation Event at ～1.4 Ga: Evidence From Mercury and Paleo-Productivity Proxies

The mid-Proterozoic (～1.8–0.8 Ga) ocean-atmosphere system is hypothesized to have experienced fluctuations in redox conditions with transient oxygenation events.

The mobility of copper, zinc, molybdenum, and tungsten in subduction zone fluids

Porphyry-type ore deposits are closely associated with subduction zones, but the ultimate source of the metals in these deposits is still uncertain.

Elucidating Multiple Electron-Transfer Pathways for Metavanadate Bioreduction by Actinomycetic Streptomyces microflavus

While microbial reduction has gained widespread recognition for efficiently remediating environments polluted by toxic metavanadate [V(V)], the pool of identified V(V)-reducing strains remains rather limited, with the vast majority belonging to bacteria and fungi.

Ordovician-Early Devonian granitic magmatism as the consequence of intracontinental orogenic activity along the Qinhang belt in South China

The early Paleozoic tectono-magmatic activity within the South China block, which is well illustrated by Ordovician？Devonian granites in the western Qinhang belt, was the response to closure of the Proto-Tethys Ocean and convergence of continental blocks.
