The Baltic Plate was an ancient tectonic plate that existed from the Cambrian Period to the Carboniferous Period. The Baltic Plate collided against Siberia, to form the Ural Mountains about 280 million years ago. The Baltic Plate, however, fused onto the Eurasian Plate when the Baltic Plate collided against Siberia when the Ural Mountains were completely formed. The Baltic Plate contained Baltica and the Baltic Shield which is now located in Norway, Sweden and Finland.
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.Barents Basin
The Barents Basin or East Barents Basin is a sedimentary basin underlying the eastern half of the Barents Sea. Lying off Russia on the continental shelf between the Kola Peninsula and Novaya Zemlya, it produces oil and gas.The Barents Basin is bordered by land and the Timan-Pechora Basin to the south, the Murmansk Rise and Murmansk Plateau to the west, the Admiralty High and the island of Novaya Zemlya to the east, and rise of Franz Josef Land to the north. The Barents Basin is subdivided into the South Barents Basin (south of the Ludlov Saddle), the North Barents Basin, and the North Novaya Zemlya Basin. The latter two are separated by a major NW–SE fault.Geology of Norway
The geology of Norway encompasses the history of earth that can be interpreted by rock types found in Norway, and the associated sedimentological history of soils and rock types.
The Norwegian mountains were formed around 400 million years ago (Ma) during the Caledonian orogeny.List of tectonic plates
This is a list of tectonic plates on the Earth's surface. Tectonic plates are pieces of Earth's crust and uppermost mantle, together referred to as the lithosphere. The plates are around 100 km (62 mi) thick and consist of two principal types of material: oceanic crust (also called sima from silicon and magnesium) and continental crust (sial from silicon and aluminium). The composition of the two types of crust differs markedly, with mafic basaltic rocks dominating oceanic crust, while continental crust consists principally of lower-density felsic granitic rocks.Tectonostratigraphy
In geology, tectonostratigraphy is stratigraphy that refers either to rock sequences in which large-scale layering is caused by the stacking of thrust sheets, or nappes, in areas of thrust tectonics or to the effects of tectonics on lithostratigraphy.
