The anticipated high demand for new vanadium resources in support of the green energy revolution will be partly met by vanadium in carbonaceous deposits. This type of deposit is particularly developed during a 200 Myr period from Cryogenian-Cambrian. During this period, anoxic conditions were widely developed and provided a template for vanadium deposition. Vanadium became available to the surface during the Neoproterozoic when anomalously high levels were introduced in large igneous provinces. Global glacial erosion transported vanadium to the oceans, along with trace elements that engendered organic carbon accumulation. The combination of vanadium and organic carbon gave rise to a range of deposits, and provides a model to support exploration for further resources.
