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
- Environmental ScienceProceedings of the National Academy of Sciences
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.

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.
