How were the Siberian Traps formed?
Formation. The source of the Siberian Traps basaltic rock has been attributed to a mantle plume, which rose until it impacted against the bottom of the Earth’s crust, producing volcanic eruptions through the Siberian Craton.
How big was the Siberian Traps eruption?
The eruptions — now called the Siberian Traps — lasted less than 1 million years but left behind Earth’s biggest “large igneous province,” a pile of lava and other volcanic rocks about 720,000 cubic miles (3 million cubic kilometers) in volume.
How many volcanoes are there in Siberia?
Volcanoes of Russia (192)
How did the Deccan Traps form?
Chapman. Evidence: Western India is home to the Deccan Traps–a huge, rugged plateau that formed when molten lava solidified and turned to rock. The Deccan Traps date back to around 66 million years ago, when magma from deep inside Earth erupted to the surface.
How are large igneous provinces formed?
Large igneous provinces (LIPs) are created during short-lived igneous events resulting in relatively rapid and high-volume accumulations of volcanic and intrusive igneous rock. These events warrant study because: The possible links to mass extinctions and global environmental and climatic changes.
What is a Deccan Trap Why is it called so?
The name Deccan is derived from the Sanskrit word ‘dâkshin’, meaning “south.” The west-central parts of the Indian peninsula are dominated by flood basalts which form a prominent terraced landscape; this form of flood basalt is called ‘trap’, after the Dutch-Swedish word ‘trappa’, meaning ‘stairs’.
What type of volcano is the Siberian Traps?
Siberian Traps. The Siberian Traps (Russian: Сибирские траппы, Sibirskiye trappy) is 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.
What was the impact of the Siberian Traps on prehistoric life?
Impact on prehistoric life. 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, or if they were themselves caused by some other, larger event, such as an asteroid impact.
What are the coordinates of the Siberian Traps?
Coordinates: 67°N 90°E / 67°N 90°E / 67; 90. The extent of the Siberian Traps (Map in German) The Siberian Traps (Russian: Сибирские траппы, Sibirskiye trappy) is a large region of volcanic rock, known as a large igneous province, in Siberia, Russia.
