Redox-sensitive trace metals have been used extensively as geochemical proxies to infer
the redox-status of marine sediments at the time of their deposition, and by extension, the …

Molybdenum is an essential trace element for human, animal and plant health and has
played an important part in the evolution of life on earth. Nonetheless, exposure to 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 …

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 Mesoproterozoic Eon [1,600–1,000 million years ago (Ma)] is emerging as a key interval
in Earth history, with a unique geochemical history that might have influenced the course of …

Patterns of uranium–molybdenum covariation in marine sediments have the potential to
provide insights regarding depositional conditions and processes in paleoceanographic …

Modern low-oxygen marine systems exhibit patterns of molybdenum–uranium covariation
that can be linked to specific attributes and processes of the depositional system, including …

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

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 …
