Correlation of stratigraphic sections from different continents suggests a worldwide interruption of carbonate sedimentation at the Triassic–Jurassic boundary, which coincided with one of the most catastrophic mass extinctions in the Phanerozoic. Both events are linked by a vulcanogenic maximum of carbon dioxide, which led to a temporary undersaturation of sea water with respect to aragonite and calcite and a corresponding suppression of carbonate sedimentation including non-preservation of… 
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
A subseafloor carbonate factory across the Triassic-Jurassic transition
Triassic-Jurassic (T-J) boundary successions record a paucity of carbonate in association with the mass extinction. Here we demonstrate that three globally disparate T-J sections contain
End-Triassic calcification crisis and blooms of organic-walled 'disaster species'
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

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

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 Late Triassic Mass Extinction Event
The Late Triassic extinction event is recognized as one of the five largest such events of the Phanerozoic and is now generally believed to have been caused by global warming and concomitant
A biocalcification crisis at the Triassic-Jurassic boundary recorded in the Budva Basin (Dinarides, Montenegro)
Volcanic activity in the Central Atlantic magmatic province, resulting in an increased flux of CO 2 , SO 2 , and CH 4 into the oceans and atmosphere, has been proposed as one of the mechanisms
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


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
Sudden Productivity Collapse Associated with the Triassic-Jurassic Boundary Mass Extinction
Carbon isotope evidence of a pronounced productivity collapse at the boundary, coincident with a sudden extinction among marine plankton, is reported from stratigraphic sections on the Queen Charlotte Islands, British Columbia, Canada.
Carbon isotope analyses of total organic carbon across the Triassic-Jurassic boundary in the classic section of Kendelbach, Austria, show that a positive excursion in δ13C values of organic carbon in
Facies and geochemical evidence bearing on the end‐triassic disappearance of the alpine reef ecosystem
A carbon and oxygen isotope profile is presented across the Triassic‐Jurassic boundary at the classic locality of Kendelbach, Austria. In conjunction with facies data it lends no support to the claim
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
A Late Triassic Impact Ejecta Layer in Southwestern Britain
An important sedimentary record of an extraterrestrial impact in the Mesozoic that will help to decipher the number and effect of impact events, the source and dynamics of the event that left this distinctive sedimentary marker, and the relation of this ejecta layer to the timing of extinctions in the fossil record are reported.

Microfacies and cyclic sedimentation of the Upper Triassic (Rhaetian) Calcare di zu (Southern Alps)
SummaryThe Rhaetian facies of the Lombardian Basin (Southern Alps) are syn-rift deposits characterized by a high rate of deposition, considerable variation of thickness and a cyclic deposition of
