The map shows that the Central Asian Orogenic Belt is located at the northern portion of Asia, and can be divided into two major parts, which are Kazakhstan orocline and Tuva-Mongolia orocline. It is bounded by the East Europe Craton, Siberia Craton, Karakum Craton, Tarim Craton, and North China Craton. [7]
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 zone runs from the North Sea to the Black Sea. The north-western part of the zone was created by the collision of Avalonia and Baltica/East European Craton in the Late Ordovician. The south-eastern part of the zone, now largely concealed by deep sedimentary basins, developed through Variscan and Alpine orogenic events.
East European Craton, the core of Baltica. Volgo-Uralian Craton, Russia (3.0–2.7 Ga) Baltic Shield, part of the East European Craton; Fennoscandian Shield, the exposed Northwestern part of the Baltic Shield in Norway, Sweden and Finland (3.1 Ga) Karelian Craton, part of the Fennoscandian Shield in Southeast Finland and Karelia Russia, (3.4 Ga)
Sarmatian Craton – The southern part of the East European Craton or Baltica, also known as Scythian Plateau; Saxothuringian plate – Structural or tectonic zone in the Hercynian or Variscan orogen of central and western Europe; Siberian Craton – Ancient craton forming the Central Siberian Plateau; South Portuguese plate; Tarim craton
About 2.5 billion years ago (in the Siderian Period), Siberia was part of a continent called Arctica, along with the Canadian Shield.Around 1.1 billion years ago (in the Stenian Period), Siberia became part of the supercontinent of Rodinia, a state of affairs which lasted until the Tonian about 750 million years ago when it broke up, and Siberia became part of the landmass of Protolaurasia.
Baltica is a paleocontinent that formed in the Paleoproterozoic and now constitutes northwestern Eurasia, or Europe north of the Trans-European Suture Zone and west of the Ural Mountains. The thick core of Baltica, the East European Craton, is more than three billion years old and formed part of the Rodinia supercontinent at c. 1 Ga. [1]
Rocks of the outer zone are estimated to have formed 1890–1860 million years ago and granitoids of the inner zone 1840–1790 million years ago. In addition to those two zones Baltybaev identifies a narrow zone of conjugation with Archean complexes between the outer zone and the Archean craton to the north and east. [ 3 ]
