The Putorana Plateau is composed of Siberian Traps. One of the major questions is whether the Siberian Traps were directly responsible for the Permian–Triassic mass extinction event that occurred 250 million years ago, [12] or if they were themselves caused by some other, larger event, such as an asteroid impact.
The Siberian Traps caused one of the most rapid rises of atmospheric carbon dioxide levels in the geologic record, [328] with the rate of carbon dioxide emissions estimated as five times faster than during the preceding catastrophic Capitanian mass extinction [329] during the eruption of the Emeishan Traps.
The scientific consensus is that the main cause of the End-Permian extinction event was the large amount of carbon dioxide emitted by the volcanic eruptions that created the Siberian Traps, which elevated global temperatures. The formation of large igneous provinces by flood basalt events could have:
The Siberian Traps was a vast area of volcanic activity in Eurasia that led to the biggest mass extinction 252 million years ago. ... The causes of these extinctions are varied — land-use change ...
The scientific consensus is that the main cause of extinction was the flood basalt volcanic eruptions that created the Siberian Traps, [65] which released sulfur dioxide and carbon dioxide, resulting in euxinia (oxygen-starved, sulfurous oceans), [66] [67] elevating global temperatures, [68] [69] [70] and acidifying the oceans.
The Cretaceous–Paleogene (K–Pg) extinction event, [a] also known as the Cretaceous–Tertiary (K–T) extinction, [b] was the mass extinction of three-quarters of the plant and animal species on Earth [2][3] approximately 66 million years ago. The event caused the extinction of all non-avian dinosaurs.
In the program, it is argued that the Permian extinction came in 3 stages; the first was caused by volcanic activity in the great Siberian Traps. This is proposed to have caused global warming, which in turn killed much of the life on land. Second, it warmed up the sea, which killed much of the marine life.
The Permian (along with the Paleozoic) ended with the Permian–Triassic extinction event, the largest mass extinction in Earth's history (which is the last of the three or four crises that occurred in the Permian), in which nearly 81% of marine species and 70% of terrestrial species died out, associated with the eruption of the Siberian Traps.
