The Frasnian–Famennian transition of the Late Devonian was one of the most critical intervals in the Phanerozoic. Sulphur isotopic pairs of carbonate-associated sulphate and pyrite sulphide from coeval sections in South China and Poland reveal frequent perturbations of sulphur cycling during this time interval. These data suggest a sudden oceanic overturn during a rapid sea-level fall probably induced by jerky block tilting in the latest Frasnian. This event was followed by long-lasting photic… Expand

Sulfur isotope evidence for low and fluctuating sulfate levels in the Late Devonian ocean and the potential link with the mass extinction event
High amplitude positive carbon isotope excursions in the Late Devonian, the punctata and Kellwasser events, reflect major perturbations in the global carbon cycle that have been attributed toExpand
Persistent oxic deep ocean conditions and frequent volcanic activities during the Frasnian-Famennian transition recorded in South China
Abstract The Frasnian-Famennian (F F) transition of Late Devonian was a critical episode in geological history, recording a major mass extinction event. In this study, we focus on an F F successionExpand
A pulse of seafloor oxygenation at the Late Devonian Frasnian-Famennian boundary in South China
Abstract The Frasnian-Famennian (F-F) mass extinction (~372 Ma) is regarded as one of the ‘Big Five’ mass extinctions events in Phanerozoic. The F-F boundary is characterized by two positiveExpand
Hydrothermally induced 34S enrichment in pyrite as an alternative explanation of the Late-Devonian sulfur isotope excursion in South China
Abstract Several Late Devonian sedimentary successions host pyrite with highly positive sulfur isotope values (δ34Spyrite). These anomalous values have been linked to marine anoxia, low sulfateExpand
Changes of palaeoenvironmental conditions recorded in Late Devonian reef systems from the Canning Basin, Western Australia: A biomarker and stable isotope approach
Abstract Although the Late Devonian extinctions were amongst the largest mass extinction events in the Phanerozoic, the causes, nature and timing of these events remain poorly restrained. In additionExpand

Abstract The Frasnian-Famennian (F-F) mass extinction is one of the “Big Five” biotic crises during the Phanerozoic, whereas the cause of this catastrophic event still remains debated. Here weExpand
Causes of the great mass extinction of marine organisms in the Late Devonian
The second of the five great mass extinctions of the Phanerozoic occurred in the Late Devonian. The number of species decreased by 70–82%. Major crises occurred at the Frasnian–Famennian andExpand

Biogeochemical controls on black shale deposition during the Frasnian-Famennian biotic crisis in the Illinois and Appalachian Basins, USA, inferred from stable isotopes of nitrogen and carbon
Abstract The Frasnian-Famennian biotic crisis is marked by two distinct intervals known as the Lower and Upper Kellwasser Events (KWEs) that in many locations are associated with deposition ofExpand

Abstract Two studied sections of the Frasnian-Famennian (F-F) boundary beds in western Thailand differ significantly in their depositional and geochemical characteristics. The highly condensed,Expand


δ34SCAS and δ18OCAS records during the Frasnian–Famennian (Late Devonian) transition and their bearing on mass extinction models
Abstract Many proposed extinction mechanisms for the Late Devonian (Frasnian–Famennian boundary — FFB) mass extinction event include the spread of anoxia in bottom waters during the two KellwasserExpand
Large shifts in the isotopic composition of seawater sulphate across the Permo–Triassic boundary in northern Italy
