Eurasia: minerals. Mainland Eurasia
The relief and minerals of Eurasia are differenta huge variety. This continent geomorphology is very often called the continent of contrasts. The geological structure, the relief of the continent, and the location of minerals in Eurasia will be discussed in detail in this article.
Mainland Eurasia: a geological structure
Eurasia is the largest continent of our planet. 36% of the land and about 70% of the earth's population is concentrated here. Almost all continents of the Earth, in fact, are fragments of two ancient supercontinents - Laurasia and Gondwana. But not Eurasia. After all, it was formed from several lithospheric blocks, which for a long time approached and, finally, were welded together into locks of folded belts.
The continent consists of a number of geosynclinal regionsand platforms: East European, Siberian, West Siberian, West European and others. In Siberia, in Tibet, as well as in the Baikal region, the earth's crust is visited by a huge number of cracks and faults.
In different geological epochs,folded belts of Eurasia were formed. The Pacific and the Alpine-Himalayan are the largest of them. They are considered young (that is, their formation has not yet ended). It is to these belts that the largest mountain systems of the mainland are the Alps, the Himalayas, the Caucasus Mountains and others.
Some parts of the mainland are regionsincreased seismic activity (as, for example, Central Asia or the Balkan Peninsula). Powerful earthquakes are observed here with considerable frequency. The presence of the largest number of active volcanoes can also boast of Eurasia.
The continent's minerals are closely related to its geological structures. But we'll talk about them later.
General features of the Eurasian landform
The relief and minerals of Eurasia are extremely diverse. They were formed in the Mesozoic and Cenozoic, within several ancient platforms, connected by mobile folding regions.
Eurasia is the second largest continent on the planet withthe average height of 830 meters above sea level. Above only Antarctica, and even then exclusively due to a powerful ice shell. The highest mountains and the largest plains are in Eurasia. And the total number of them is much greater than on other continents of the Earth.
Eurasia is characterized by the greatest possibleamplitude (difference) of absolute heights. It is here that the highest peak of the planet is - Mount Everest (8850 m) and the lowest point of the world - the level of the Dead Sea (-399 meters).
Mountains and plains of Eurasia
Almost 65% of the territory of Eurasia is occupied by mountains, plateaus and uplands. The rest belongs to the plains. The five largest mountain areas on the continent:
- Himalayas.
- Caucasus.
- Alps.
- Tien Shan.
- Altai.
Himalayas - the highest mountain range not onlyEurasia, but the whole planet. They occupy about 650 thousand square kilometers of area. It is here that the "roof of the world" is located - Mount Jomolungma (Everest). In the whole history 4469 mountain climbers conquered this peak.
On this continent is also located the Tibetanthe highlands are the largest in the world. It occupies a huge area - two million square kilometers. Many famous rivers of Asia (Mekong, Yangtze, Indus and others) originate in the Tibetan Plateau. Thus, this is another geomorphologic record that Eurasia can boast of.
The minerals of Eurasia, by the way, oftenlie in the zones of folding. So, for example, the bowels of the Carpathian Mountains are very rich in oil. And in the mountains of the Urals actively mined precious minerals - sapphires, rubies and other stones.
Plains and lowlands in Eurasia are also many. Among them is another record - the East European Plain, which is considered the largest on the planet. It stretches from the Carpathians to the Caucasus by almost 2500 thousand kilometers. Twelve states are located within this plain, in whole or in part.
Relief of Eurasia: highlights and interesting facts
For impressive orographic records veryIt is easy to miss the less large-scale, but not less interesting features of the continent. In the relief of Eurasia there are, in fact, all forms of relief known to modern science. Caves and karst mines, cars and fjords, ravines and river valleys, dunes and barkhans - all this can be seen within the largest continent of the Earth.
In Slovenia is the famous plateau Karst,geological features of which gave the name to a whole group of specific forms of relief. Within this small limestone plateau, there are several dozen beautiful caves.
Quite a lot in Eurasia and volcanoes, both active andand extinct. Klyuchevskaya Sopka, Etna, Vesuvius and Fujiyama are the most famous of them. But on the Crimean peninsula you can see the unique mud (on the Kerch peninsula) or the so-called failed volcanoes. A vivid example of the latter is the mountain known as the Ayu-Dag.
Minerals of the continent
Eurasia ranks first in the world for the common reserves of many mineral resources. In particular, the bowels of the continent are extremely rich in oil, gas and ores of non-ferrous metals.
In the mountains, as well as on the shields (projections of the foundationplatforms) of Eurasia are concentrated solid deposits of iron and manganese ores, as well as tin, tungsten, platinum and silver. To the deflections of the foundations of the ancient platforms are confined huge reserves of fuel mineral resources - oil, gas, coal and oil shale. Thus, the largest oil deposits are developed in the Persian Gulf, on the Arabian Peninsula, in the shelf of the North Sea; natural gas - in Western Siberia; coal - within the East European Plain and in Hindustan.
What else is rich in Eurasia? Minerals of non-metallic type are also extremely common on the mainland. So, on the island of Sri Lanka is the world's largest deposit of rubies. In Yakutia, diamonds are mined, in Ukraine and Transbaikalia - granite of the highest quality, in India - sapphires and emeralds.
In general, the main minerals of Eurasia -oil, gas, iron ore, manganese, uranium, tungsten, diamonds and coal. In terms of production of many of these resources, the continent has no equal throughout the world.
Eurasian natural resources: a table and major deposits
It should be noted that the mineral resources of the continentare extremely uneven. Some states in this plan are openly fortunate (Russia, Ukraine, Kazakhstan, China, etc.), and others - not very (like, for example, Japan). Below are listed the most important minerals of Eurasia. The table also contains information on the largest mineral deposits of the continent.
Mineral resource (type) | Mineral resource | The largest deposits |
Fuel | Oil | Al-Gawar (Saudi Arabia); Rumaila (Iraq); Daqing (China); Samotlor (Russia) |
Fuel | Natural gas | Urengoy and Yamburg (Russia); Galkynysh (Turkmenistan); Agajari (Iran) |
Fuel | Coal | Kuznetsky, Donetsk, Karaganda basins |
Fuel | Oil shale | Bazhenovskoe (Russia), Boltysh (Ukraine), Mollaro (Italy), Nordlinger-Rees (Germany) |
Ore | Iron ore | Krivoy Rog (Ukraine), Kustanai (Kazakhstan) basins; Kursk Magnetic Anomaly (Russia); Kirunavar (Sweden) |
Ore | Manganese | Nikopol (Ukraine), Chiatura (Georgia), Usinsk (Russia) |

Finally
The largest continent on our planet is theEurasia. The minerals of this continent are very diverse. The world's largest reserves of oil, natural gas, iron and manganese ore are concentrated here. In the bowels of the continent contains a large number of copper, uranium, lead, gold, coal, precious and semiprecious stones.
