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 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, [ 21 ] – estimated to have killed 90% of species existing at ...
Geologically, it is mainly composed of basalt from the Siberian Traps. This remote and mostly untouched area includes several ecosystems, such as taiga, forest tundra, tundra, Arctic deserts, lakes, and rivers. The vegetation marks the meeting point between Western and Eastern Siberian floras. The plateau is on a major reindeer migration route ...
The volcanically produced Siberian Traps, the largest flood basalts of the Phanerozoic (the last 539 million years), mantle about 40 percent of the Siberian craton. [19] [29] The Siberian craton is known for its large mineral resources. The town of Norilsk is the world's largest supplier of nickel. In 2011 one-fifth of the world's production of ...
Trap rock, also known as either trapp or trap, is any dark-colored, fine-grained, non-granitic intrusive or extrusive igneous rock. Types of trap rock include basalt, peridotite, diabase, and gabbro. [1] Trap is also used to refer to flood (plateau) basalts, such as the Deccan Traps and Siberian Traps. [2]
During the eruption of the Siberian Traps, some 5 to 16 million cubic kilometers (1.2 to 3.8 million cubic miles) of magma penetrated the crust, covering an area of 5 million square kilometres (1.9 million square miles), equal to 62% of the area of the contiguous states of the United States.
Much of the Siberian Traps Large Igneous Province is inside. [1]The area is of about 400,000 square miles (1,000,000 km 2) in Krasnoyarsk Territory and Sakha Republic, between the Yenisei and Lena rivers.
