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 …

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 …

Sedimentary rocks deposited across the Proterozoic–Phanerozoic transition record extreme
climate fluctuations, a potential rise in atmospheric oxygen or re-organization of the seafloor …

Sedimentary pyrite formed in the water column, or during diagenesis in organic muds,
provides an accessible proxy for seawater chemistry in the marine rock record. Except for …

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

The main controlling factors of organic matter accumulation in the Upper Ordovician Wufeng–
Lower Silurian Longmaxi Formations are complex and remain highly controversial. This …

The Wufeng organic-rich shale is widespread in the Upper Yangtze platform, and it is one of
the most advantageous shale gas producers in China. Its deposition commenced with the …

Abstract The early Toarcian Oceanic Anoxic Event (Jenkyns Event) was associated with
major world-wide climatic changes with profound effects on the global carbon cycle. This …

To explore the sedimentary environment and the background of the source area of organic-
rich shales in the Wufeng–Longmaxi Formations in the northern Sichuan Basin, samples …
