Siberian Traps

This article is about the geological feature. For the chess opening, see Siberian Trap.
The extent of the Siberian Traps (map in German)

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 two million years and spanned the Permian–Triassic boundary, or P–T boundary, which occurred around 251.9 million years ago. The Siberian Traps are believed to be the primary cause of the Permian–Triassic extinction event, the most severe extinction event in the geologic record.[1][2][3][4] Subsequent periods of Siberian Traps activity have been linked to a number of smaller biotic crises, including the Smithian-Spathian, Olenekian-Anisian, Middle-Late Anisian, and Anisian-Ladinian extinction events.[5]

Large volumes of basaltic lava covered a large expanse of Siberia in a flood basalt event. Today, the area is covered by about 7 million km2 (3 million sq mi) of basaltic rock, with a volume of around 4 million km3 (1 million cu mi).[6]
