The evolving redox chemistry and bioavailability of vanadium in deep time

The coevolving chemical speciation and biological functions of V due to earth's changing surface redox conditions demonstrate the crucial links between the geosphere and biosphere in the evolution of metabolic electron transfer pathways and biogeochemical cycles from the Archean to Phanerozoic.

Dwindling vanadium in seawater during the early Cambrian, South China

Vanadate Retention by Iron and Manganese Oxides

Anthropogenic emissions of vanadium (V) into terrestrial and aquatic surface systems now match those of geogenic processes, and yet, the geochemistry of vanadium is poorly described in comparison to

The occurrence of vanadium in nature: its biogeochemical cycling and relationship with organic matter—a case study of the Early Cambrian black rocks of the Niutitang Formation, western Hunan, China

Vanadium in the black rocks has economic and environmental impacts. In sediments, it is broadly disseminated as a multivalent metal element mainly sensitive to redox settings. Globally in petroleum,

Synchrotron X-ray spectroscopy for investigating vanadium speciation in marine sediment: limitations and opportunities

Vanadium (V) exists in a number of oxidation states in the environment, potentially making it a useful chemical tracer of both modern and ancient redox conditions in Earth's oceans. However, the use

Global biogeochemical cycle of vanadium

A quantitative summary of the global biogeochemical cycle of vanadium (V), including both human-derived and natural fluxes, is provided and suggests that the flux of V in rivers has been incremented by about 15% from human activities.



Application of a new vanadium valence oxybarometer to basaltic glasses from the Earth, Moon, and Mars

Abstract The redox states of volcanic and impact melts from the Earth, Moon, and Mars have been estimated from the valence state of V in basaltic glasses (Sutton et al. 2005). The V valence has been

Vanadium in ancient sedimentary rocks of marine origin

The redox state of the mantle during and just after core formation

Modelled core–mantle equilibration in a magma ocean that became progressively deeper as accretion proceeded indicates that the mantle would have become gradually oxidized as a result of Si entering the core.

Water and the Oxidation State of Subduction Zone Magmas

Integrated measurements of redox-sensitive ratios of oxidized iron to total iron (Fe3+/ΣFe) determined with Fe K-edge micro–x-ray absorption near-edge structure spectroscopy and pre-eruptive magmatic H2O contents of a global sampling of primitive undegassed basaltic glasses and melt inclusions indicate a direct link between mass transfer from the subducted plate and oxidation of the mantle wedge.

Geochemical Assessment of Iron and Vanadium Relationships in Oxic Soil Environments

Geochemical assessment has become a cost-effective and highly accurate tool for estimating metal contamination, especially in those cases where the level of contamination is not considered severe.
