Siberia, also known as Siberian Craton, Angaraland (or simply Angara) and Angarida, [1] is an ancient craton in the heart of Siberia. Today forming the Central Siberian Plateau , it formed an independent landmass prior to its fusion into Pangea during the Late Carboniferous - Permian .
A craton is an ancient part of the Earth's continental crust which has been more or less stable since Precambrian times. Cratons whose ancient rocks are widely exposed at the surface, often with relatively subdued relief, are known as shields.
The Anabar Shield (larger pale blue dot) in the north of the Siberian Craton. The Anabar Shield (Russian: Анабарский щит) is a shield in Siberia. It is an exposed basement of the Siberian Craton. Together with the Aldan Shield to the southeast, the Anabar Shield is one of the main features of the craton.
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 ...
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 Central Asian Orogenic Belt is located between the East European craton and North China craton on the Northwest-Southeast direction, and between Siberian craton and Tarim craton on the Northeast-Southwest direction. [7] The belt extends for approximately 2500 km in the East-West direction. [7]
Aldan Shield (Russian: Алданский щит) is a shield in Siberia.It is an exposed basement of the Siberian Craton.Together with the Anabar Shield further to the northwest, the Aldan Shield is one of the main features of the craton.
Arctica, or Arctida [1] is a hypothetical ancient continent which formed approximately 2.565 billion years ago in the Neoarchean era. It was made of Archaean cratons, including the Siberian Craton, with its Anabar/Aldan shields in Siberia, [2] and the Slave, Wyoming, Superior, and North Atlantic cratons in North America. [3]
