The Siberian Traps and the End-Permian mass extinction: a critical review

  title={The Siberian Traps and the End-Permian mass extinction: a critical review},
  author={A. Saunders and M. Reichow},
  journal={Chinese Science Bulletin},
The association between the Siberian Traps, the largest continental flood basalt province, and the largest-known mass extinction event at the end of the Permian period, has been strengthened by recently- published high-precision 40Ar/39Ar dates from widespread localities across the Siberian province[1]. We argue that the impact of the volcanism was amplified by the prevailing late Permian environmental conditions—in particular, the hothouse climate, with sluggish oceanic circulation, that was… Expand

The physics of this process including necessary magnitudes of basaltic intrusion, mixing and mobilization of coal and basalt, ascent to the surface, explosive combustion, and the atmospheric rise necessary for global distribution are described and constrain. Expand
High temperature and low oxygen perturbations drive contrasting benthic recovery dynamics following the end-Permian mass extinction
The end-Permian mass extinction event was the greatest loss of biodiversity ever experienced on the planet. The event is thought to have been triggered by the initiation of the volcanic eruptions ofExpand

Abstract The Siberian Traps Large igneous province was a key player in the end-Permian extinction and climatic change due to degassing from lavas and heated sedimentary rocks. Although the specificExpand
Dynamic interplay between climate and marine biodiversity upheavals during the early Triassic Smithian -Spathian biotic crisis
Abstract In the aftermath of the Permian-Triassic boundary mass extinction (~252 Ma) ― the most dramatic biotic crisis of the Phanerozoic ― changes in climate, the carbon cycle, and biodiversityExpand

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
Rapid Eruption of the Siberian Traps Flood Basalts at the Permo-Triassic Boundary
Laser-heating 40Ar/39Ar data indicate that inception of Siberian Traps volcanism coincided with a profound faunal mass extinction at the Permo-Triassic boundary 249 � 4 million years ago; these data thus leave open the question of a genetic relation between the two events. Expand

The most intriguing possibility is that the greatest mass extinction of the Phanerozoic left signals very similar to the end-Cretaceous mass extinction but was produced by entirely Earth-bound processes. Expand

Modeling indicates that measured short-term changes in δ13C at the boundary are best explained by methane release with mass mortality and volcanic degassing contributing in secondary roles, which results in excessively high levels of atmospheric CO2 if they occurred on time scales of more than about 1,000 years.

Hydrothermal venting of greenhouse gases triggering Early Jurassic global warming
Abstract The climate change in the Toarcian (Early Jurassic) was characterized by a major perturbation of the global carbon cycle. The event lasted for approximately 200,000 years and was manifestedExpand
The stability of the stratospheric ozone layer during the end-Permian eruption of the Siberian Traps
An extended version of the Cambridge two-dimensional chemistry–transport model is used to evaluate quantitatively the possibility that the eruption of the Siberian Traps through older organic-rich sediments synthesized and released massive quantities of organohalogens, which caused widespread O3 depletion and allowed increased terrestrial incidence of harmful ultraviolet-B radiation.
