The Putorana Plateau is composed of Siberian Traps. 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, [13] or if they were themselves caused by some other, larger event, such as an asteroid impact.
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 the time.
The deposit was formed 250 million years ago during the eruption of the Siberian Traps igneous province (STIP). The STIP erupted over one million cubic kilometers of lava, a large portion of it through a series of flat-lying lava conduits below Norilsk and the Talnakh Mountains. [59]
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 ...
It was created 250 million years ago by a process known as plume volcanism, in which a huge body of magma rose to the surface from 1,800 miles (2,897 kilometers) inside the Earth. [1] Next, the glaciers expanded the canyons and formed the present-day river gorges and deep narrow lakes (Lama, Keta, Glubokoye, Khantayskoye, Ayan, etc.) creating ...
Scientists have revived a worm that was frozen 46,000 years ago — at a time when woolly mammoths, sabre-toothed tigers and giant elks still roamed the Earth. A worm has been revived after 46,000 ...
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.
The central part of North Asia is a large igneous province called the Siberian Traps, formed by a massive eruption which occurred 250 million years ago. The formation of the traps coincided with the Permian–Triassic extinction event. Geographically, North Asia is a subregion of Asia.
