Vanadium is a metal that receives increasing attention due to its possible toxicity and its
increased use in society, ie in high-grade steel and in vanadium redox-flow batteries …

Uranium (U) is of enormous global importance because of its use in energy generation,
albeit with potential environmental legacies. While naturally occurring U is widespread in the …

Paleoredox conditions are commonly evaluated based on elemental proxies but, despite
their frequency of use, most of these proxies have received little comparative evaluation or …

Interactions between microorganisms and clay minerals influence the transport and cycling
of metal contaminants in both marine and terrestrial environments. The present study was …

This paper is a synthesis of the use of selected trace elements as proxies for reconstruction
of paleoproductivity and paleoredox conditions. Many of the trace elements considered here …

Redox-sensitive transition group elements are involved in almost all fundamental
geochemical processes. Of these elements, vanadium (V) contributes a particularly powerful …

Trace elements are actively cycled in seawater, are essential components for marine life,
and are transported to the seafloor where they can become enriched in marine sediments …

The distributions of certain minor and trace elements in marine sediments should potentially
provide forensic tools for determining the redox conditions of the bottom waters at the time of …

The black shale submember of core shales of Pennsylvanian Kansas-type cyclothems is
highly enriched in redox-sensitive trace elements (TEs) relative to the overlying gray shale …

The oxygen content of the Earth's surface environment is thought to have increased in two
broad steps: the Great Oxygenation Event (GOE) around the Archean–Proterozoic boundary …
