The end‐Triassic mass extinctions represent one of the five most severe biotic crises in Earth history, yet remain one of the most enigmatic. Ongoing debate concerns the environmental effects of the Central Atlantic Magmatic Province (CAMP) eruptions and their linkage with the mass extinction event across the Triassic‐Jurassic boundary. There is conflicting paleo‐evidence for changes in atmospheric pCO2 during the extrusion of the CAMP basalts. Studies on sediments from European and Pacific… 
Catastrophic ocean acidification at the Triassic-Jurassic boundary
Palaeobotanical and geochemical evidence indicate a sudden rise in atmospheric carbon dioxide (CO2) across the Triassic-Jurassic boundary, probably reflecting the combined effect of extensive

Earth’s climate is predominantly controlled by the fluctuation of greenhouse gases, specifically CO2 and CH4, over geologic time. The late Triassic is a period of abrupt climate change that has been

The end-Triassic is regarded as one of the five major mass extinction events of the Phanerozoic. This time interval is marked by up to 50% of marine biodiversity loss and major changes in terrestrial
Modelling the impact of pulsed CAMP volcanism on pCO2 and δ13C across the Triassic–Jurassic transition
Abstract A sharp negative δ13C excursion coincides with the end-Triassic mass extinction. This is followed by a protracted interval of 13C enrichment. These isotopic events occurred simultaneously
Environmental changes and carbon cycle perturbations at the Triassic–Jurassic boundary in northern Switzerland
The Triassic–Jurassic boundary is characterized by strong perturbations of the global carbon cycle, triggered by massive volcanic eruptions related to the onset of the Central Atlantic Magmatic
Carbon cycle perturbation and stabilization in the wake of the Triassic‐Jurassic boundary mass‐extinction event
The Triassic‐Jurassic boundary mass‐extinction event (T‐J; 199.6 Ma) is associated with major perturbations in the carbon cycle recorded in stable carbon isotopes. Two rapid negative isotope
Additive effects of acidification and mineralogy on calcium isotopes in Triassic/Jurassic boundary limestones
The end‐Triassic mass extinction coincided with a negative δ13C excursion, consistent with release of 13C‐depleted CO2 from the Central Atlantic Magmatic Province. However, the amount of carbon
Multiple phases of carbon cycle disturbance from large igneous province formation at the Triassic-Jurassic transition
The end-Triassic mass extinction (ca. 201.4 Ma) coincided with a major carbon cycle perturbation, based on an ∼5‰−6‰ negative excursion in δ 13 C TOC (total organic carbon) records. Both events


Stability of atmospheric CO2 levels across the Triassic/Jurassic boundary
The relative stability of atmospheric CO2 across this boundary suggests that environmental degradation and extinctions during the Early Jurassic were not caused by volcanic outgassing of CO2, and other volcanic effects—such as the release of atmospheric aerosols or tectonically driven sea-level change—may have been responsible for this event.
Terrestrial and marine extinction at the Triassic-Jurassic boundary synchronized with major carbon-cycle perturbation: A link to initiation of massive volcanism?
Mass extinction at the Triassic-Jurassic (Tr-J) boundary occurred about the same time (200 Ma) as one of the largest volcanic eruptive events known, that which characterized the Central Atlantic
Carbon cycling and chronology of climate warming during the Palaeocene/Eocene transition
Current models of the global carbon cycle lack natural mechanisms to explain known large, transient shifts in past records of the stable carbon-isotope ratio (δ13C) of carbon reservoirs. The
Methane oxidation during the late Palaeocene thermal maximum
Carbon isotope records across the Latest Palaeocene Thermal Maximum (LPTM) display by a remarkable delta 13 C excursion of at least -2.5 per mil that occurred within 10X10 3 yrs. Thermal dissociation
Massive dissociation of gas hydrate during a Jurassic oceanic anoxic event
Carbon-isotope analyses of fossil wood demonstrate that isotopically light carbon dominated all the upper oceanic, biospheric and atmospheric carbon reservoirs, and that this occurred despite the enhanced burial of organic carbon.
New geochemical evidence for the onset of volcanism in the Central Atlantic magmatic province and environmental change at the Triassic-Jurassic boundary
The Late Triassic–Early Jurassic was a time of major global change; however, the fundamental processes driving these changes are less than clear. We have determined the Re and Os abundances, and Os
Dating the end-Triassic and Early Jurassic mass extinctions, correlative large igneous provinces, and isotopic events
The end-Triassic marks one of the five biggest mass extinctions, and was followed by a well-known second-order extinction event in the Early Jurassic. Previously published geological time scales were
Timing the end-Triassic mass extinction: First on land, then in the sea?
The end-Triassic marks one of the five biggest mass extinctions, but current geologic time scales are inadequate for understanding its dynamics. A tuff layer in marine sedimentary rocks encompassing

Evidence for Late Jurassic release of methane from gas hydrate
Four Late Jurassic carbonate successions deposited in the Tethys-Atlantic Ocean record a negative carbon isotope excursion of at least 2‰. The excursion is present in both organic and carbonate
