Middle Permian Extinction A major extinction in the Middle Permian 260 to 270 million years ago preceded the huge end-Permian extinction. Wignall et al. (p. 1179) present a detailed analysis of the Middle Permian event from rocks in southwest China. The extinction coincided with extensive nearby volcanic eruptions. A major drop in carbon isotope values followed the extinction event, implying massive disruption of the carbon cycle. Fossiliferous rocks from southwest China show that a major… Expand
Global climate perturbations during the Permo-Triassic mass extinctions recorded by continental tetrapods from South Africa
Several studies of the marine sedimentary record have documented the evolution of global climate during the Permo-Triassic mass extinction. By contrast, the continental records have been lessExpand
Contrasting geochemical signatures on land from the Middle and Late Permian extinction events
The end of the Palaeozoic is marked by two mass-extinction events during the Middle Permian (Capitanian) and the Late Permian (Changhsingian). Given similarities between the two events in geochemicalExpand
Carbon Isotopic Evolution Characteristics and the Geological Significance of the Permian Carbonate Stratotype Section in the Northern Upper‐Yangtze Region, Southern China
The Permian global mass extinction events and the eruption of the Emeishan flood basalts in the Upper Yangtze region should display certain responses during the evolution of carbon isotope. In thisExpand
Emeishan mantle plume activity and carbon isotope responses in the Middle Permian, South China
Abstract During the Permian, Emeishan mantle plume activity created a large igneous province and deeply impacted carbon isotope records in marine carbonate strata in South China. To evaluate theExpand
On the causes of mass extinctions
The temporal link between large igneous province (LIP) eruptions and at least half of the major extinctions of the Phanerozoic implies that large scale volcanism is the main driver of massExpand
Discovery of a major negative δ13C spike in the Carnian (Late Triassic) linked to the eruption of Wrangellia flood basalts
Major climate changes and mass extinctions are associated with carbon isotope anomalies in the atmosphere-ocean system and have been shown to coincide with the onset of large igneous provinces (LIPs)Expand
Establishing the link between Permian volcanism and biodiversity changes: Insights from geochemical proxies
Abstract Current understanding of biodiversity changes in the Permian is presented, especially the consensus and disagreement on the tempo, duration, and pattern of end-Guadalupian and end-PermianExpand
Middle Permian organic carbon isotope stratigraphy and the origin of the Kamura Event
Abstract Large carbon cycle perturbations associated with the Middle Permian (Capitanian) mass extinction have been widely reported, but their causes and timing are still in dispute. Low resolutionExpand
Remains of trilobites and other species discovered in a volcanic ash bed of the end-Permian, Yangtze craton, South China
ABSTRACT The remains of trilobites and other species were unexpectedly discovered in a volcanic ash layer beneath the Permian–Triassic Boundary (PTB). Based on a biostratigraphic investigation of theExpand
Are Late Permian carbon isotope excursions of local or of global significance
We present a new, biostratigraphically calibrated organic and inorganic C-isotope record spanning the basal Late Permian to earliest Triassic from southern Guizhou (Nanpanjiang basin, South China).Expand


Large igneous provinces and mass extinctions
Comparing the timing of mass extinctions with the formation age of large igneous provinces reveals a close correspondence in five cases, but previous claims that all such provinces coincide withExpand
A temporal link between the Emeishan large Igneous Province (SW China) and the end-Guadalupian mass extinction
Abstract Previous studies have suggested that there were two mass extinction events in the Late Permian: one that occurred at the Permo-Triassic (P/T) boundary (251 Ma) and a second, smaller massExpand
Methane Release from Igneous Intrusion of Coal during Late Permian Extinction Events
Unusually large and locally variable carbon isotope excursions coincident with mass extinctions at the end of the Permian Period (253 Ma) and Guadalupian Epoch (260 Ma) can be attributed to methaneExpand
A negative carbon isotope anomaly associated with the earliest Lopingian (Late Permian) mass extinction
Abstract Palaeozoic life was severely affected in a pair of mass extinction events at the beginning (earliest Lopingian, 260 million years ago) and the end (251 million years ago) of the LateExpand
Main Deccan volcanism phase ends near the K-T boundary: Evidence from the Krishna-Godavari Basin, SE India
Abstract Recent studies indicate that the bulk (80%) of the Deccan trap eruptions occurred over less than 0.8 m.y. in magnetic polarity C29r spanning the Cretaceous–Tertiary (K–T) boundary.Expand
Volatile fluxes during flood basalt eruptions and potential effects on the global environment: A Deccan perspective
Abstract We examine the role that flood basalt eruptions may have played during times of mass extinction through the release of volcanic gases. Continental flood basalt provinces have formed byExpand
Palaeoenvironmental change during the end-Guadalupian (Permian) mass extinction in Sichuan, China
Abstract The end-Guadalupian mass extinction has been investigated in Sichuan province, SW China. In the south of the province the platform carbonates of the Maokou Formation are overlain by theExpand
Sedimentation and Lithofacies Paleogeography in Southwestern China Before and After the Emeishan Flood Volcanism: New Insights into Surface Response to Mantle Plume Activity
Investigations into Permian sedimentation and reconstruction of paleogeography in SW China are aimed at characterizing sedimentary responses to the Emeishan mantle plume. In addition to erosionalExpand
Re-evaluating plume-induced uplift in the Emeishan large igneous province
Numerical and fluid dynamic modelling predicts that mantle plumes should generate a broad domal uplift (>1,000 km wide, 500 to ⩾1,000 m high) preceding volcanism in large igneous provinces. TheExpand
Emeishan large igneous province, SW China
In recent years, there have been major advances in our understanding of the Emeishan large igneous province (LIP) of SW China following publication of a number of LIP-focused investigations of theExpand
