Redox-sensitive trace metals as paleoredox proxies: A review and analysis of data from modern sediments
WW Bennett, DE Canfield - Earth-Science Reviews, 2020 - Elsevier
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 …

A re-assessment of elemental proxies for paleoredox analysis
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 …

Definition of new trace-metal proxies for the controls on organic matter enrichment in marine sediments based on Mn, Co, Mo and Cd concentrations
Trace metal enrichments in sedimentary deposits are of prime interest because they are
governed by processes that also control the production and preservation of organic matter …
