Effect of end-Triassic CO2 maximum on carbonate sedimentation and marine mass extinction

  title={Effect of end-Triassic CO2 maximum on carbonate sedimentation and marine mass extinction},
  author={M. Hautmann},
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… Expand
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 carbonExpand
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 containExpand
End-Triassic calcification crisis and blooms of organic-walled 'disaster species'
The Triassic–Jurassic (T–J) mass-extinction event is marked by isotope anomalies in organic (δ 13 Corg) and carbonate carbon (δ 13 Ccarb) reservoirs. These have been attributed to a (rapid) 4-foldExpand
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 eventsExpand
The Triassic–Jurassic boundary event from an equatorial carbonate platform (Ghalilah Formation, United Arab Emirates)
The Ghalilah Formation, UAE provides a complete and continuous equatorial shallow-water carbonate sequence through the Upper Triassic to Lower Jurassic interval. In higher latitudes, this interval isExpand
Carbon cycle changes during the Triassic-Jurassic transition
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 terrestrialExpand
Terrestrial Impacts of the Central Atlantic Magmatic Province on western Pangea
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 beenExpand
The end-Triassic negative δ13C excursion: A lithologic test
Abstract The end-Triassic mass extinction is associated with a large negative carbon isotope excursion, which has been interpreted as reflecting the rapid injection of 13 C depleted CO 2 or methaneExpand
Bentho-planktonic evidence from the Austrian Alps for a decline in sea-surface carbonate production at the end of the Triassic
A high-resolution micropalaeontological study, combined with geochemical and sedimentological analyses was performed on the Tiefengraben, Schlossgraben and Eiberg sections (Austrian Alps) in order toExpand
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 concomitantExpand


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 AtlanticExpand
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. Expand
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 inExpand
Carbon isotope anomaly and other geochemical changes at the Triassic-Jurassic boundary from a marine section in Hungary
Most mass extinctions are linked with carbon isotope excursions, implying that biotic crises are coupled with changes in the global carbon cycle. The isotopic evolution during the end-TriassicExpand
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 claimExpand
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 wereExpand
Secular oscillations in the carbonate mineralogy of reef-building and sediment-producing organisms driven by tectonically forced shifts in seawater chemistry
The primary mineralogy of oolites and early marine carbonate cements led Sandberg [Nature 305 (1983), 19–22] to divide the Phanerozoic Eon into three intervals of `aragonite seas' and two intervalsExpand
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.

Palaeoclimatology (Communication arising): CO2 and the end-Triassic mass extinction
An isotopic study of Mesozoic fossil soils suggests that the atmospheric concentration of carbon dioxide across the Triassic–Jurassic boundary was relatively constant, but this is inconsistent with high-resolution evidence from the stomatal characters of fossil leaves, which suggest the linkage between pCO2, global warming and the end-Triassic mass extinction remains intact.

Palaeoenvironmental interpretation of a Triassic-Jurassic boundary section from Western Austria based on palaeoecological and geochemical data
A section spanning the Triassic-Jurassic boundary is described from near the village of Loruns in the Vorarlberg region of western Austria. At Loruns, the uppermost Triassic is characterised byExpand
