Asian Geological History And General Considerations

Asian Geological History And General Considerations. Asia is not only the largest continent on the planet but the youngest and most complex continent. Although development began four billion years ago in Asia. Higher than half of the continents are still active in the earthquake. Producing arcs of the new continental material technique in the eastern and southeastern parts of the surrounding islands. In these places, new land continues to emerge and added to most parts of the continent. Through accidental collisions between island arcs and the mainland.

Asia has the largest mountain on the surface of the Earth. Tibetan Plateau and the mountains around the Himalayas, the Karakoram Mountains. The Hindu Kush, the Pamirs, the Kunlun Mountains, and the Tianshan Mountains. With its huge scale and young, Asia has many forms of earth’s land extreme surface. Because of its highest and lowest points, the longest coastline, and the largest continental shelf zone. Asia’s vast mountains, diverse coastlines, and extensive continental plains and valleys have had a great impact on human history. Asia produces many fossil fuels (oil, gas, and coal), and a major contributor to the global production of multiple minerals. (for example, three-fifths of the world’s tin) emphasizes the importance of his geology for the world’s population Welfare.

Construction framework

The Asian form masks a complex geological history, before responsible for the active deformation of the existing landscape. Its structural unit determined according to the Asian movement arrangement. The part that formed or is now part of a single tectonic plate. Whose configuration derived from the formation and movement of the plate. Defined from those of the structural unit according to its fossil alignment (ie, now inactive). So, convenient to discuss Asian tectonic frameworks based on two separate maps. One showing its ancient tectonic units (the oldest one) and the other showing its new tectonic units (new and active).

Asian Geological History And General Considerations

Rendering to the philosophy of plate tectonics, powers inside the Earth drive parts of earth’s crust in several courses. The continent’s formation results, where the ocean opened and closed. When the ocean tears, it tears a continent and is closed along the subduction zone the ocean opens. The subduction plane is the submarine settlement below the adjacent tectonic plates and assimilated into the mantle. The closure of the ocean culminates in continental collisions and may involve accumulating huge tectonic collages. This includes small continental debris, island arches, large sediment deposits, and occasional debris from seafloor material. Useful to depict these enhanced objects and the lines or sutures to which it attaches them when defining the units. Which they draw the Asian paleo formation maps.

Continuous convergence after a collision can more interrupt the construction tiles that have installed along the new secondary line, through faults. Interruptions after a collision can reactivate old construction lines (sutures). These secondary structures dominate and define new structural units in Asia. But, it should mention earlier continental collisions led to the creation of secondary structures, increasing the structural diversity of the continent.

It divides Asian ancient tectonic units into one category: the continental core and the orogenic belt (mountain building). The continental core includes platforms stable during the Precambrian period (4 billion and 541 million years ago). Covered by undisturbed sedimentary rocks; the name includes Angaran (or Eastern Siberia), Indian and Arabic platforms.

General Considerations

Many smaller platforms that are more deformed than large platforms, called para platforms. These include Yangtze platforms and North China (or China and North Korea). North Tarim fragments (known as Western China Serindia), Kontum blocks (Southeast Asia). The orogenic belt comprises large structural patches that grow around the continental core. Selected sections are Altaids, Tethysides (subdivided into Alpide and Cimmerides), and the Pacific Rim Region. The Alps and the annulus are undergoing structural deformation, they continue to develop in earthquakes and volcanic eruptions evolving.

Asian Geological History And General Considerations

The continental Precambrian cores formed by the same plate tectonic progression of constructing later orogenic belts. But best to treat them for three reasons. First, the nucleus accounts for only a quarter of Asia’s territory. Less than one-third (ie less than 10% of Asia’s total space) comprises exposed Precambrian rocks. It allows geologists to study their development. Second, the fossils of the Precambrian rocks are poor, making global and even regional correlation difficult. During most of Phanerozoic (ie, in the past 541 million years), the nucleus remained stable. This accumulated a structural collage around the orogenic belt of Phanerozoic.

General Considerations

For the collision between the Indian subcontinent and Eurasia, the Asian tectonic evolution ended 40 to 50 million years ago. Later new tectonic developments in Asia have destroyed the existing structures of the continent. Asia’s first-class new tectonic units are stable in Asia, Arab, and Indian cratons. The extreme regions of the Alpide plate (the Arab and Indian platforms collide with it along with the Eurasia plate). The island’s arches and marginal basins.

In chronological order

It locates the oldest rock in Asia in the mainland’s heart. They have discovered over 3 billion years a rock on the Precambrian outcrops. The Angara’s and India platforms and platform platforms in northern China. They form primitive magma and scattered island arched sedimentary rocks. Interspersed between younger basalts and ultrabasic rocks, exposed along with so-called greenstone belts. The basement of the Angaran platform formed 1.5 billion years ago. But, the final integration of the Indian platform lasted 600 million years ago, including several mountain constructions. Peak activities between 2.4 billion and 2.3 billion years ago. A Billion years ago, 1.7 and 1.6 billion years. And 1.1 billion to 600 million years ago. On the Arab platform, the form of the basement is 9 million years ago accumulate bows and micro-continents. Ended 6 million years ago, although accumulation micro-continents have over 25 million years ago. The basement and maybe an independent fragment of Africa.

General Considerations

In the north of para-platform, Chinese geologists have identified a tense magma island arc melting from molten rock. Formed by the subduction of the oceanic crust, rising. Solidifying to form an igneous rock 35 to 3 billion years ago. These arcs connected to the original nucleus by collision until the end of the twentieth century (200 million years ago). The platform of the northern part of China merged around 1.7 billion years past. The Yangtze River platform is fresher, and the mature determined mountaineering occasion is 2.5 billion years.

Asian Geological History And General Considerations

Its final integration took habitation 800 million years ago. The Kontum chunk is little identified. It has the lowest age of the Precambrian metamorphic rocks of 2.3 billion years. Despite the thermal events and the oldest obsolete, in the Middle Cambrian. The period (5 million years ago) fell and shows the time of final integration. The North Tarim fragment is a thin sheet trapped in a younger orogenic belt. Its Precambrian history and the history of the Yangtze River platform are not different. Although not all the major faults of sedimentary and tectonic evolution or details of sedimentary succession are relevant. The debris of Tarim is 800 million years ago stabilize.

General Considerations

As other Asian continent nuclei are completing their consolidation. Orogenic deformation begins again along the current southeast and southwestern edges of the Angaran platform. This reactivation marks the beginning of the long cycle of subduction, depletion of large sedimentary cells. Develop the submarine and the front edge of the upper plate. Accumulate of wedge-shaped subduction hyperplasia and now known as Altaid Asia (named after the Altai Mountains). The associated magma action subduction and many collisions. Deformation of the Altaids orogenic belt. The first part of the late Proterozoic late (8.5 million years ago). To the Mesozoic (2.2 million years ago), in areas. Such as Mongolia and Siberia, which lasted until even Luo Ji period (145 million years ago).

General Considerations

Creation of the Altaid collage is parallel to the late Paleozoic combination of the Pangea supercontinent. (or Pangea) (320 million to 250 million years ago). Altaids is in the northern part of the Paleo-Tethys Sea (known as the Paleo-Tethys Sea). A triangular giant east of Pangea. Pulling a continental material from the southern edge of Paleo-Tethys, moving north. Rotates around the western apex of the Tethys triangle, just similar to the windshield wiper. For the continent known as the Cimmerian continent. A collage of continental materials gathered around the Yangtze River platform and the Kontum block. More or less 210 and 180 million years ago, these materials collided with Altaid Asia to form Cimmeride orogenic belt.

When the Cimmerian continent sailed north, a new ocean, the New Tethys. Opened behind it and in the northern part of the Gondwana continent. After the fall of Gondwana, the new ocean closed 155 million years ago. The two splinters of Gondwanaland, India, and Arabia hit with other parts of Asia. Miocene (23 to 5.3 million years ago). In the Eocene (ie, 5.6 to 34 million generations ago). They call the orogenic belts resulting from the destruction of the new Tethys. Continental collision Alpides results, forming the current Alps – the Himalayas. Both Cimmerides and Alpides produced by the removal of the Tethyan Ocean, known as Tethysides.

General Considerations

Most of the island arcs bordered the eastern part of Asia by the subduction of the Pacific Ocean. Open the basin behind the arches during the Cenozoic period (the last 66 million years). This action continues today and is the main source of tectonic effects in South and Southeast Asia. (earthquakes and volcanic motion often lead to altitude). In the south and southwest, India and Arabia continue to move north. An average move of 2.4 and 1.6 inches (6 and 4 cm) per year. These movements caused a large volume of two-thirds distortion in South Asia’s and produced a continuous chain of mountains.

Between Turkey and Burma, expanding in the Tibetan Plateau of Turkey, Iran, and China. In these plateaus, the mountains are young, the Caucasus, and the Tianshan Mountains. The impact of major faults, because of northern Anatolia and the Altun Mountains (Altun), and the rift valleys. Such as the northern part of the Baikal Basin, each related to seismic work. It witnesses the wide-ranging effects of Arab and Indian convergence with stable Asia. Where no significant movement tectonism observed.
