The Siberian Traps (Russian: Сибирские траппы, romanized: Sibirskiye trappy) are a large region of volcanic rock, known as a large igneous province, in Siberia, Russia. The massive eruptive event that formed the traps is one of the largest known volcanic events in the last 500 million years. The eruptions continued for roughly ...
The Siberian Traps was a vast area of volcanic activity in Eurasia that led to the biggest mass extinction 252 million years ago. The distant mountains are remains of basalt lava flows, and the ...
The Siberian Traps eruptions had unusual features that made them even more dangerous. The Siberian lithosphere is rich in halogens extremely destructive to the ozone layer, and evidence from subcontinental lithospheric xenoliths indicates that as much as 70% of their halogen content was released into the atmosphere.

The Deccan Traps are a large igneous province of west-central India (17–24°N, 73–74°E). They are one of the largest volcanic features on Earth, taking the form of a large shield volcano. [2] They consist of many layers of solidified flood basalt that together are more than about 2,000 metres (6,600 ft) thick, cover an area of about ...
Wilkes Land crater. Coordinates: 70°S 120°E. Wilkes Land crater is an informal term that may apply to two separate cases of conjectured giant impact craters hidden beneath the ice cap of Wilkes Land, East Antarctica. These are distinguished by the names Wilkes Land anomaly and Wilkes Land mascon (mass concentration), based on terms used in ...
The Siberian Traps were formed by one of the largest-known volcanic events of the last 251 million years of Earth's geological history. Their activity continued for a million years and some scientists consider it a possible cause of the "Great Dying" about 250 million years ago, [20] – estimated to have killed 90% of species existing at the time.
The Columbia River flood basalt province comprises more than 300 individual basalt lava flows that have an average volume of 500 to 600 cubic kilometres. The Steens Basalt captured a highly detailed record of the Earth’s magnetic reversal that occurred roughly 15 million years ago. Over a 10,000 year period, more than 130 flows solidified ...
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:
