World Continent General Considerations For South America Geological History

World Continent General Considerations For South America Geological History. We can group the geological history of South America into three distinct stages of development. Each of them conforms to an important division of geological time. The first phase comprised a pre-Cambrian period (4,600 to 541 million years ago). Characterized by a series of complex pieces that merged and called for a craton protocontinental cortical stable dispersion block.

Its second level coincides with the Paleozoic (541 to $252 million). Which the craton and accumulated materials contributed to form the supercontinent Gondwana (or Gondwana), and then even larger Pangu (Pangu). The third stage, emerge of the current continental formation, occurred in the Mesozoic and Cenozoic (252 million years). Including Pangu and Gondwana, open the South Atlantic and create the disintegrated Andes Cordillera.

The current tectonic framework of South America comprises three basic units: the old craton, the nearest Andes and several basins. Five-cratons (Amazonia, San Francisco, Luis Alves, Upper Paraguay, and La Plata). The Precambrian nucleus of South America and (except for Paraguay), now shown as arranging South Dwarf from the North solid. In the eastern part of the African continent; a series of other Precambrian bark blocks have increased along the southern American edge throughout the geological period.

The high range and the Andes, along the entire western edge of the African continent. Rise over the inter-mountain plateau and represent the Pacific Plate. The Cenozoic collisions of South America (66 million years ago) open to the South Atlantic. A large capacity of sediment between the cratons of the Andes and the entire eastern edge of the Andes, decaying.

South America Geological History: Trans-Amazonian Cycle

Transamazonian rocks can subdivide into three distinct groups. Orogenic belts such as the Amazonian Maroni-Itacaiúnas belt or San Francisco’s Salvador-Juazeiro belt. It covers stable rocks such as the Bahia Chapada Diamantina formation or the Carajas and Roraima platforms Sediments. Large groups of dikes (plate-like intrusions of igneous rocks in sedimentary strata). The orogenic belt is the ancient mountains formed along the edge of the continent. Such as the earth’s crust (the lower layer of the earth’s crust) and then rises. Such as the Maroni-Itacaiúnas belt, or the collision between the continental blocks, El Tandil belt in Buenos Aires, Argentina.

They believe these collisions formed the supercontinent (sometimes referred to as the first market) 1.8 billion years ago. The sedimentary caprock of the supercontinent (preserved in the Amazon Craton). Includes sediments in the collected rhyolite and debris racks, deep and extensive, and erases earlier suture restrictions. There is a wide range of iron and manganese layered deposits in these sequences, such as near Caracas, Brazil. In the early stages of a continental plate diffusion. It produced many basic rock dams, including 60 miles (100 km) wide in central and western Uruguay. It now houses hundreds of gabbro dams in a 150-mile (240 km) section.

South America Geological History: Brazilian Cycle

Today the rocky Brazilian cycle manifested in a series of orogenic belts. The Precambrian cratons established the end of the first supercontinent end of time. During the merger, form the pre-deformed continental crust (making 1 mil millions) To 541 million years. Most South America, covering the platforms Brazil, Guyana, and southern Venezuela, grew together with Africa. Formed a huge supercontinent Gondwana in the southwestern part of the country; this Gondwana, Cambrian blocks, including Santa Marta Colombia, Arequipa Peru, and Patagonia, the Argentine block, accumulated after the Paleozoic period.

Brazilians in the state of Mato Grosso in southern Brazil represent the Brazilian orogeny. There, the green schist (related to granite), the limestone platform and quartzite. The important processes of the moraine red stratum. Reconstruction of the collision of the passive continental margin (ie no active volcano) and Paraguay Alto Paraguay. Active Craton Edge (now covered by the Parana River Basin). The suture zone explained between the two cratons corresponds to the Paraguay-Araguaia line, mafic and ultramafic rocks discovered today.

Several other Brazilian belts are well known. Such as the complex Borborema belt and the Dom Feliciano belt in southern Brazil and Uruguay. For the collision between the La Plata River and the Kalahari River in Africa today. The Dom Feliciano belt is a complex suture zone. It traps the typical rocks of the Late Proterozoic arc method between two cratons; in the early Cambrian period (541 million years ago), these The rock covered by rhyolite plateau. There is a surprising coincidence between this suture. Known as the Brazilian-pan-African suture, and start the crack scheme that opens the Atlantic. The Pampas Mountains of Argentina are a good example of the Brazilian belt. Formed by the island arch arrangement and several small continental plates.

PALEOZOIC ERA

South America Geological History: First Paleozoic Event

The early Paleozoic rocks of the continent represented the rupture of the first supercontinent. May relate which to separate underground rocks in eastern Andes of South America. The western Andes, in western South America. It established this separation. A series of passive continental margins along the western African continent from Venezuela and Colombia to central Argentina. The Precambrian platforms merged during the Brazilian cycle. Today’s fringe edges characterized by clastic rocks of the Cambrian period (ie 500 million years ago). Many of trilobites and rocks, such as Cordillera in eastern Bolivia. Early Paleozoic ruptures that produced these margins triggered that developed several large internal basins. The continent (eg, Amazon, Parnaíba, Parana, and Chaco Basins). Thick sedimentary rock deposits have accumulated in these basins.

The subduction of the oceanic crust activated the Paleozoic passive edge of the early part of the Cambrian. To Ordovician (ie, forcing main continental plate fall below the edge of oceanic crust) (making 500 to 470 million years). Oceanic crust consumed, the subduction stops. A series of small continental blocks collide with the west side of the continent. The established result land parcels (transportation) in Ecuador, Colombia and Venezuela’s East Cordillera. The silurian period ended (419 million years ago). Those correspond ages of the orogenic belts of Glenville North American Rocks (1.3 1200 years old). Affinity with American Wildlife Devonian (419 to 359 million years) suggested that these neighborhoods were once part of North America.

Further south, another series of blocks fell into the mainland. These include the Arequipa block in southern Peru and Bolivia. The Precordillera region in the Midwest of Argentina and the Patagonia region in southern Argentina. The continent of Patagonia in southern Chile, smaller blocks of rock with ocean affinity has increased.

During the subduction before these collisions. It formed a series of north-south plutonic and volcanic belts on the coast of the continent, parallel to the coast. As the coastal fringe accumulated the continental crust. The belts moved over 250 miles (400 km) west. Today in northern Patagonia, west of Pampa Sierras, Cordillera in eastern Bolivia, and northern Argentina. Colombia and the eastern Cordillera of Venezuela.

The collision of these blocks produced a series of peripheral basins. It resulted from orogenic belt deformation and basement rock accumulation in the orogenic zone. Examples of early Paleozoic basins are the Beni basin in Bolivia and Alhuampa and Las Breñas basins in northern Argentina. Claromecó, the last Paleozoic basin in northern Patagonia. Now occupied by a sedimentary deposit of over 5 miles thick, which formed with the Karoo Basin in southern Africa. Collisions cause both basins. Influence of the Konya microcontinent on Gondwana.

South America Geological History: Form Pangea.

The Paleozoic ended with the last mixture of Gondwana. Together with Laurasia in the north formed the late Permian of the Paleozoic. It’s subduction below the western edge of Pangea stopped. The igneous rock formed by the volcanic arc develops along with the central mountain range. Between Chile and Argentina and then develops along the western continental margin. It is transient, compose the rock changes from andesite to the main rhyolite. These changes in mineral composition show that the compression state. Correlate with subduction passes extensive magma movement and extension of the earth’s crust. Huge magma pieces, including flood basalt and 2.5 miles (4 km) thick rhyolite deposits. From southern Peru to the Argentina-Chile border. Further north, this action eliminated during the Cenozoic era because of the rise of the Andes and volcanic coverage.

South America Part Of The Seven Continent World Map And History

South America, the fourth continent of the world. The southern part of the land and often referred to as the New World, the Western Hemisphere or the Americas. The continent of Africa is a compact, triangular, wide in the north, and Cape Point in Chile in the south.

South America bounded by the Caribbean Sea, northwest and north, the Atlantic Ocean to the northeast. The east to southeast, and the west to the Pacific. In the northwest, it will connect the Isthmus of Panama to North America, 50 miles once reduced which (80 km). El Paso Drake, south of Cape Horn, separates South America from Antarctica.

Besides the south, few islands border the continent. These include the glacial coastal islands of Argentina and Chile. It locates the Falkland Islands (Malvinas) to the east of southern Argentina. In the west, the West Indies extends from Trinidad to Florida, but they associate these islands with North America. Most of the rest are small marine islands off the coast of South America. The Galapagos Islands in the Pacific Ocean includes.

South America has a total space of ​​6,878,000 square miles (17,814,000 square kilometers). Accounting for one-eighth of the Earth’s land territory. Distinct north and south stretch 4.700 miles from Point Gallinas, Columbia, Cape Horn. While his old stuff extends 3.300 miles from Cape Blanco, Brazil to Point Pariñas, Peru. At sea level, Aconcagua is the 22,831-foot (6.959-meter) above the border between Argentina and Chile. It is not only the highest point on the African continent but the highest altitude in the Western Hemisphere. The Valdes Peninsula on the southeast coast of Argentina includes the lowest point, 131 feet (40 meters) above sea level. In terms of its size, the continent’s coastline of 15,800 miles long and short.

The name of the United States comes from the name of the Italian navigator Amerigo Vespucci. One of the original European explorers in the New World. The word “United States” only applied to South America, but the name applied to the entire land. Since Mexico and Central America share Iberian heritage only throughout South America. They divide the entire region in the name of Latin America.

The geological formation of South America comprises two asymmetric parts. In the east, larger, several stable shields that form mountains and separated by large basins, including the giant Amazon basin. The west occupied by the Andes. The Andes, which formed the South American plate moving westward, forced the oceanic plate to move westward beneath it. Along a huge backbone of the entire Pacific coast that formed the continent. It fills the basin between the eastern and eastern highlands of the Andes. With large amounts of sediment washed by the main rivers of the continent and its tributaries.

Except for Antarctica, no other continent can penetrate the South. Although northern North America extends north of the equator. Three-fifths of its land in the tropics, but it reaches the latitude below Antarctica. It locates most of the Andes in the tropics. But they include large temperate or cool climates near the equator, a unique environment. The rich altitude, creating an unparalleled climate and ecological zone, which may be the most prominent feature of South America.

They believe the original inhabitants of South America were descendants of the same Asian. Who moved from Siberia to North America during the recent Ice Age (Wisconsin?). Few of the individuals survived Europeans in 1500 years. Most of them died of the disease or were mixed with African-Americans (Brazilians). Few parts of the African continent now industrialized, with modern cities. But people in rural areas still follow an agricultural lifestyle. The abundance of minerals and renewable resources reasonable. Economic development in most of the regions lags the most advanced industries in the world. But, a concern on a rapid increase in these resources and the destructive use of these resources.

World Continent General Considerations For North America Geological History

World Continent General Considerations For North America Geological History. During the geological period, the mainland has collided and separated many times. When they separated, it forms a new ocean basin between the divergent fragments through the seafloor propagation procedure.

The propagation, which originates from the ridge of the ocean. It offset (to stay in the surface section of ​​the planet) when sub-ducting. Treatment bent through the seabed and sag along the path towards the tilt inside Earth trenches of the deep sea. The closure of the ocean basin by subduction of the seabed led to a continental collision.

Materials that move from the propagating ridge to a subduction zone include rock blocks as thick as 60 miles (100 km). It calls this hard earth’s outer shell a lithosphere, unlike the hotter, smoother asthenosphere. It calls the part of the lithospheric plate that descends into the asthenosphere in the subduction zone the plate. Many lithospheric plates that make up the current surface of the Earth defined by interconnecting systems of ridges. Subduction zones, and lateral motion cracks (called transition faults). Throughout the geological period, as the new plates formed, expanded, contracted and disappeared, the plate boundary scheme continued to develop.

World Continent General Considerations For North America Geological History

It calls the outermost layer of the lithosphere the cortex. It comprises a low-density material crystallized from molten rock (magma) produced by partial fusion of lithosphere or asthenosphere. The average thickness of the oceanic crust is 4 miles (6.4 km). It localizes the ocean plateau and seamounts areas of the thick oceanic crust generated by underwater volcanic movement. Promoted by thermal jets of magma or pillars rising from the depths of the Earth’s interior (ie, mantle). The oceanic crust is short-lived, formed at the top of the ocean and destroyed in the trenches. Its average age is 60 million years.

The continental crust is thicker, at an average of 22 miles (35 km) and then the oceanic crust. Can explain the average surface elevation of the seabed above 3 miles (4.8 km) (density of the Archimedes principle). The arrangement and origin of the continental crust are more complex than that of the oceanic crust. Formed in the subduction zone. Lateral growth produced by adding scrapers from the upper part of the ocean plate as they sub-duct under the continental margin. This edge marked by a line of volcanoes, often in volcanic arcs, forming an increased to the crust.

The result of partial melting of the asthenosphere wedges on the descending plate. Below the continental plate (by releasing water from slab to promote fusion, which reduces the melting point of the wedge). The subduction zone (a sea plate descending from another ocean plate) in the ocean basin produces volcanic arcs; it calls these island arches. Island arc make up materials that transition between the ocean and the continental crust, including thickness and composition. The first continent shows to have formed by form several island arcs.

Continental crust resists subduction. The average age of the continent near to 2 billion years, over 30 times the average age of the ocean crust. The continent the main repository of information on evolve the Earth’s geology. Knowing their formation requires understanding the processes in their evolving ocean basins.

North America Geological History: Construction framework Structural plane

North America is unusual between continents. Most of the orogenic belts surrounded by an ancient stable low-lying interior. (with associated subduction or continental collisions with old or actual ridges from crustal deformation). These lowlands include the internal platforms of the Laurentian and crystalline rock, covered by a layer of flat sedimentary rock.

The outer orogenic belt of the continent originates from the limits of the plate. They are in the Paleozoic in the east (542-250 million years ago). The Mesozoic in the west (to date, 252.2 million years). The coastal sediments of the Arctic Ocean in the north, the southern Gulf of Mexico. Young volcanic zone in the west cover these areas and damaged. The rupture of the Paleozoic orogenic belt between the Appalachian Mountains in Newfoundland. Caledonian River in eastern Greenland resulted from an unsuccessful seabed expansion along the Mid-Atlantic Ridge and later resolved. To the east, the Appalachians and the Greenland Caledonians separated from Caledonide in Europe.

North America Geological History: Canadian Shield

Canadian Shield the main section of ​​North America. It exposes the Precambrian rocks (those that exceeded 542 million years of rock) to the surface. The sea between Canada and Greenland destroyed the shield. It expands between the Labrador Sea and the Baffin Bay between 90 million and 40 million years ago. It cracks then moved eastward from Greenland to form the Reykjanes Ridge. Which now separates the North American plate from the European plate. It covers Greenland’s shield with ice. In the past 2.5 million years, the Canadian shield has the center of glaciers. The continental ice sheet has been advancing southward.

Shields are the sum of at least four discrete continents that merged between 2000 and 1.8 billion years ago. The 3 constituent continents act like a solid matrix, recognized the craton, during which it serves as the stable craton; slave cratón in the northwest, Nain’s hole is in the northeast, and Craton is in Churchill. The southern part of the province is not a rigid gap and can be a composite origin. It truncates the structural particles of the craton at their edges. It suggests they originated from fragments of the largest continent formed over 2.6 billion years ago. For their age, the small residual basins of the flat Precambrian sedimentary rocks in the shield. Although they are more in common with the internal platforms and basins.

Internal platform and swimming pool

World Continent General Considerations

Horizontal sedimentary rock formations are higher than the Precambrian crust, beyond the boundaries of the Canadian shield. The sedimentation cover is less than a mile thick on the platform. But increases to 2.5 miles it adds 4 km to adjacent channels. 4 miles (6 km) to the outer orogenic belt. Sedimentary rocks give sensitive records of differential settlement in the lower part of the earth. Geomorphology evolution of the outer orogenic belt, sea level fluctuations, and climate changes associated with latitude drift in the continent.

North America Geological History: Paleozoic orogenic belt

They discovered corrosive remains of ancient mountains along the eastern, northern and southern edges of the continent. It formed these .mountains between 400 million and 300 million years ago. When North America collided with other continents to form the ancient Pangea supercontinent. When the Ouachita orogenic belt (mountain) established, they guaranteed it to South America in South America. The Appalachian orogenic belt faces the southeastern margin and northwestern Africa. When the orogenic belt Caledon collided, it faced the northeastern margin of margin and the Franklin orchard. With the balance of the Arctic.

Volcano bracket now collides with the crust north of the Brooks Range in Northern Europe and Alaska. The orogenic belt along with the interior of the continent composed of North American native sedimentary rocks. The parts closest to the modern ocean are more diverse, including rock masses that originate outside the continent. A surprising observation of paleogeographic reconstruction is that the current ocean basin. Open along the line near the closed line of the pre-Paleozoic ocean.

Passive continental edge

World Continent General Considerations

Less than 200 million years of sediment and rock cover the eastern, northern and southern margins of the continent. These worn edges extend below the ocean as a shallow continental shelf. Important fishing section formed when the Atlantic and Arctic oceans and the Gulf of Mexico open. The river transports large amounts of sediment to the Gulf of Mexico and the Arctic Ocean. In these two areas, the resulting sediment now drills a salt block like from below a finger. Called a salt dome several miles in diameter. In the Arctic, over 40 million years ago, sediments wrinkled counterclockwise as Greenland moved away from northeastern Canada. Sediments deposited along the Atlantic Ocean’s edge are underwater sediments.

North America Geological History: Mesozoic and Cenozoic orogenic belts

The youngest mountain range (Cordilleras) forms along the western edge of the continent and around the Caribbean Sea. Developed of Cordilleras occurred after the Atlantic opened. North America moved westward to the Pacific region of 180 million years ago. As a result, sedimentary rocks and volcanic rocks fall from the Pacific plate. The Pacific plate subducted and added to the main (western) edge of the continent (so-called suspicious terrain). Volcanic within the continental margin. For 30 million years, North America has been growing beyond the East Pacific.

World Continent General Considerations

The center of submarine expansion, which led to the basic division of Cordilleras. Seafloor west of the diffusion axis moves to one side (north) comparative to North America. Part of continental margin passes through the diffusion peak. (ie, California and northwest Canada ) characterized by faults (San Andreas and Charlotte) Queen (Fairweather) displaced to the right and has no ditches or volcanic arches.

The current bottom of the Caribbean originates from the submarine plateau of the Eastern Pacific Basin. More or less 80 million years ago, it infiltrated the gap between the North and South American plates. As the two plates (including the Western Atlantic) move westward. Subduction and arc volcanic movement take place on the eastern edge of the Caribbean. Where the northern and southern margins of the Caribbean Sea are severed and dismembered. They relate Arctic volcanic action in Central America to the subduction of the Pacific Ocean bottom. The Middle America Trench on the Pacific coast of the region; reflected in the Atlantic soil subduction under the volcanic arc of the Lesser Antilles.

It relates the volcanic movement of the new generation (ie 65 million years ago) to the subduction zone. The mantle feathers and the procedure of crustal extension. Volcanic arches occur in Lesser Antilles, Central America, the Cascade Mountains, Mexico, the Gulf of Alaska and the Aleutian Islands. Volcanic ash flows covered the vast areas east of major volcanic arcs in Mexico. New Mexico, and from 38 to 28 million years ago. It can scatter the lines (or footprints) of volcanic action from east to west. From melting locations or hot spots below the continental panels. An example of this footprint is the Anahim volcanic belt in central British Columbia. 

The lava plain in the Snake River in Idaho. Yellowstone crater marks the active eastern end of the Snake River track. The basalts of Columbia and the Oregon Plateau, between the ages of 14 to 17 million years. Resemble lava floods associated with set up mantle plumes. Flood basalts on the eastern coast of Greenland and offshore associated with separate Greenland and Northwest Europe. Under the influence of the Icelandic mantle 68 million years ago. It relates the lava in the western coastal areas of Greenland to separate of Greenland and Baffin Island. The Cuenca and Cordillera Mountains are vast bark stretch areas in the western United States. Contain many small volcanic fields, less than 15 million years old.

North America Part Of The Seven Continent World Map And History

North America the third largest continent in the world, between the Arctic Circle and the Tropic of Cancer. It extends from over 5,000 miles (8,000 kilometers) to 500 miles (800 kilometers). From the Arctic and the equator and extends 5,000 miles from east to west. It covers a part of ​​9,355,000 square miles (24,230,000 square kilometers).

North America occupies the northern part of the land, often referred to as the New World, the Western Hemisphere or the Americas. The continent of North America is triangular, the north is north, and the north is the apex; it associates with the continent the world’s largest island, Greenland, and the Arctic Islands. The West Indies, Haida Gwaii (Queen Charlotte Islands) and Coastal islands such as the Aleutian Islands.

North of North America is the Arctic Ocean, the North is the North Atlantic Ocean; the South is the Caribbean Sea, and the West is the North Pacific Ocean. In the northeast, Greenland separated from Iceland in the Danish Strait. The northwestern part of Alaska separated from the Bering Strait and the Bering Strait narrower. The only land connection in North America is South America, in the narrow isthmus of Panama.

Mount McKinley in Alaska is the highest point on the continent at an altitude of 20,310 feet (6,190 meters). The Death Valley in California is the lowest at 282 feet (86 meters) above sea level. With a coastline of 37,000 miles (60,000 kilometers), the North American coastline is second only to Asia. It described the greatest number of notches, in the northern half.

The name of the United States comes from the name of the Italian businessman and navigator Amerigo Vespucci. The original European explorers to visit the New World. While the word the US, applied only to the southern half of the continent, it applies to the entire land. It calls the part that extends north of the Isthmus of Panama North America. While it calls the part that extends to South America. According to authorities, North America is not in the isthmus of Panama. But in the Tehuantepec Strait, and it calls the middle section Central America. They include this definition, part of Mexico in Central America, although the country is in North America.

To overcome this anomaly. We can classify countries in Mexico, and countries in Central and South America in the name of Latin America. While they know the United States and Canada as Anglo-Americans. This cultural division is real. But, Mexico and Central it connects America (including the Caribbean) to the rest of North America. Through strong natural geographical connections. Greenland divided but next to North America. Geographers characterized the region from the southern border of the United States to the northern border of Colombia as Central America. Unlike Central America, which includes Mexico. Definitions of Central America include the West Indies.

North America has the oldest rocks on earth. It builds its geological edifice around a stable platform of Precambrian rocks called the Laurentian Shield. In the shield’s southeast stands the ancient Appalachian Mountains; in the west is the youngest and high mountain range, occupying one-third of the land section of ​​the continent. Between the two mountains are a flat space of ​​the western Great Plains and the central lowlands.

The African continent is rich in natural resources, including abundant mineral resources. Vast forests, lots of fresh water and the world’s most fertile soil. These make North America one of the most developed regions in the world, residents enjoy a high standard of living. Per capita income is highest in North America, and per capita, food intake is higher than in other continents. Although it accounts for less than 10% of the world’s population, it’s per capita energy consumption four times world average.

It believed that the first inhabitants of America were ancient Asians. Migrated from Siberia to North America in the last glacier march, known as the Wisconsin Glacier stage. The latest major division of the Pleistocene (2.6 million to 11, 700 years ago). These descendants of these peoples, the various Native American communities and the Eskimos (Inuit) have replaced by old world people. The descendants of Europeans are the largest group, followed by African Americans and Asians; in addition, many Latin Americans who are mixed breeds of European and Native Americans.

World Continent General Considerations For Europe Geological History

World Continent General Considerations For Europe Geological History. Precambrian rocks exist in three basic tectonic settings. First a shield, such as the Baltic Sea Shield. A large space of ​​stable Precambrian rock that surrounded by later orogenic belts (mountain shapers).

The second is from the basement to the young Phanerozoic sediment coating (ie sediments have established since the start the Paleozoic). For example, the Precambrian base behind the sediments of the Russian platform, from the Baltic Shield Ural Mountains. Cambrian rocks stretched in the Phanerozoic sediments of southeast England.

Ukrainian block is a raised plot of the Precambrian basement, higher than the surrounding plain of young sediments. The third environment occurs as a relic (residual relief form) in younger orogenic belts. For example, Bohemian blocks of the Cambrian rock that have trillions of years in the Channel Islands. The English Channel and 16,000 billion years of rock. Which was the last Hercynian belt of the Paleozoic in the Middle Proterozoic period? In the Hercynian belt of Bavaria, detrital zircons can trace back to 3.84 billion years ago. But the origin of these rocks unclear.

World Continent General Considerations For Europe Geological History

Paleozoic sedimentary rocks occur in sedimentary basins such as the Russian platform. They never subjected to any period of orogenic movement. So still Caledonian and internal sediments of the Hercynian still flat, fossilized, or orogenic. Which deformed by bending and pushing, part of Recrystallized and experienced intruder of granite. In the sedimentary basin affected by the orogenic movement. A well-preserved discovery of Cenozoic sediments and Russian platforms, in the North Sea. Deformation, metamorphic heights in the alpine state scheme.

In chronological order

We can summarize the geological developments in Europe as follows. Ancient rocks (over 2.5 billion years old) are the oldest rocks of the Precambrian. It shows in the Baltic shields of the north, Ukraine and northwest Scotland. Two major Proterozoic orogenic belts (ie, 2.5 billion to 541 million years). It extends to the central and southern shields of the Baltic Sea. So, the shield has a composite origin that has several remains of the Precambrian orogenic belt.

More or less 540 million to 500 million years ago, it opened a series of new oceans. The final closure produced the mountains of the Caledonian, Hercynian and Ural belts. There is ample evidence that these belts developed through the tectonic plate. It disposes, and each belt has a history of hundreds of millions of years. Form the belt caused the supercontinent of Pangea; its fragmentation began 200 million years ago, forming a new ocean – the Tethys Sea.

World Continent General Considerations

The closure of the subduction block by the ocean 500,000 years ago led to alpine orogeny. Example, create alpine orogeny, extending from the Atlantic to Turkey. It has many orogenic mountains (which stay as mountains). These include the Pyrenees, Swiss and Austrian Alps, Mountain Bética, Atlas Mountains. The Apennines, Dinara Alps the Taurus Mountains, and the Carpathian Mountains, and Bridges. During open Tethys (180 million years ago), the Atlantic Ocean opened.
