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 …

Devonian climate and reef evolution: insights from oxygen isotopes in apatite
MM Joachimski, S Breisig, W Buggisch… - Earth and Planetary …, 2009 - Elsevier
Conodonts, microfossils composed of carbonate-fluor apatite, are abundant in Palaeozoic–
Triassic sediments and have a high potential to preserve primary oxygen isotope signals. In …

Massive release of hydrogen sulfide to the surface ocean and atmosphere during intervals of oceanic anoxia
Simple calculations show that if deep-water H2S concentrations increased beyond a critical
threshold during oceanic anoxic intervals of Earth history, the chemocline separating sulfidic …

Biogeochemical evidence for euxinic oceans and ecological disturbance presaging the end-Permian mass extinction event
The Permian–Triassic Boundary event at 252.2 Ma marks the largest extinction of marine
fauna in the Phanerozoic and there is a wide consensus that the extinction coincided with an …
