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 …

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 …

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 …

The redox-sensitive transition element molybdenum is present in the Earth's crust at trace
concentrations but is abundant in seawater, marine sediments, and ancient sedimentary …

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 …

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 …

“The Answer to the Great Question... Of Life, the Universe and Everything... Is... Forty-two,”
said Deep Thought, with infinite majesty and calm…“I checked it very thoroughly,” said the …

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 …

Recent studies have identified a range of new applications of trace-metal concentration data
in the analysis of paleoceanographic systems. In restricted anoxic marine systems, trace …
