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, [ 22 ] – estimated to have killed 90% of species existing at ...

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]

The Siberian Traps are thought to have played a significant role in the Permian–Triassic extinction event 252 million years ago. Formation of the Emeishan Traps began 260 million years ago. The Late Devonian extinction occurs about 374 million years ago. The Ordovician–Silurian extinction event occurs between 450 and 440 million years ago.
