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.

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.
Solid Phase Speciation and Solubility of Vanadium in Highly Weathered Soils.
It is demonstrated that kaolinite and Fe oxides can effectively sequester V in highly weathered soils by mechanisms of adsorption and structural incorporation and are relevant to other Fe-oxide-rich environments under acidic and oxic conditions.


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.
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.

The hydrogeochemistry of thermal springs on Mutnovskii Volcano, southern Kamchatka
This paper reports results from a hydrogeochemical study of thermal springs on Mutnovskii Volcano. The solutions of boiling pots and the pore water of thermal localities in the Donnoe Field were
