Peat depositional environments, the sites where and conditions under which peat
accumulates, significantly influence a resultant coal's physical properties, chemical …

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 …

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 …

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 …

Although marine productivity is a key parameter in the global carbon cycle, reliable
estimation of productivity in ancient marine systems has proven difficult. In this study, we …
