The old ocean plate between Arabia and Eurasia may be broken, he says

According to a study published in Science Magazine Solid Earth, researchers at Göttingen University of Germany gathered data from a strange phenomenon in the evolution of the world surface: NEOTHETHYS Ocean Plate Goes. The region is going through a horizontal rupture process with a crack extending from Southeast to Northwest Iran.

This sign was the ocean bed between the Arab and Eurasian continents, but it has been sinking for a long time. The results show that breaking occurs due to the forces implemented by the Zagar Mountains in Iraq. Actually, This process is not so new, because it is already happening in the last 20 million years.

For researchers, The study can help to understand how the evolution of the world surface is affected by the internal processes of the planet.. As a result, for millions of years, the convergence of these continents resulted in the dynamics observed. But they also They concluded that the weight of the Zagar Mountains would not be enough to explain the depth of depression reaching about 3 or 4 kilometers.

Scientists created models to understand how the surface around the Zagros Mountains sank. Realizing that the weight of the mountains does not explain the depth of this depression, Other internal factors in the world may have affected this phenomenon.

“Considering the moderate topography in the northwest region of Zagros, it was surprising to find that both sediments accumulate in the region we worked for. This means that black depression was greater than the burden of depression. In an official statement at the Department of Structural and Geothermal Geology at the University.

In addition to deepening about the internal processes of the world, the study investigated the reasons behind the deterioration of this plate and the sinking. At the end of the article, researchers say they set some factors responsible for these phenomena and dynamics.

What is an ocean plate?

The surface of the world consists of several tectonic plates, both ocean and continent. However, they have different characteristics that affect the internal processes of the planet. For example, the movement of these plates was responsible for the formation of the mountains and the distribution of the continents over time – this movement stems from the convection of hot material into the terrestrial capes.

Ocean plates are formed within different borders, Magma emerges from the meso-oeanic dorsal regions and creates a new ocean shell. After reaching the surface, the magma cools and solidifies, which causes magmatic rocks such as basalt to be extruded. This continuous process results in the formation and expansion of ocean plates.

The ocean shell is mainly made of basalt, a magmatic rock rich in iron, magnesium and calcium. On the other hand, the continental shell contains a loyal rock rich in granite, silica, sodium and potassium. Anyway, it is noteworthy that both can contain other types of rocks.

“There are two types of shells: the continent and ocean that differs in terms of composition and thickness. The distribution of such shells usually corresponds to the division between continents and ocean basins, but the dipped continental platforms are formed by the continental shell. Brit Britannik encyclopedia explains.

The ocean plates are more intense and this difference constitutes them at the bottom of the oceans. Besides, The ocean shell is less than 200 million geologically younger than being constantly renewed. Continental shell may exceed one billion years, some rocks can last more than four billion years.

The ocean shell forms the ocean base and represents approximately 70% of the planetary area. Despite the lowest area, it has a much larger volume due to continental shell thickness. That is, an average of 6 kilometers thick, continental shell can reach up to an average of 40 kilometers.

Oceano plate stay and sleep

In the model created by scientists, the size of depression, the topography of the region and the black cape of the region were combined to simulate this rupture. The result revealed that the weight of the Zagar Mountains is not the only reason for the depth of this fissure up to 4 kilometers.

According to the team, This depression is the result of the additional weight of the ocean plate connected to the Arab plate. Thus, this process pulls the area down, which can explain the observed effects.

The results are They show that some of the rupture has already occurred between Iraq and Türkiye, but that Iran should move towards the northwest. The calculation model shows that depression is significantly shallow in this area, which can justify the violation of the plate in this region.

“This plate pulls the area down and makes room for more sediment accumulation. The depression full of sediment becomes much more shallow, which makes the license plate break this area and alleviate the power of attraction. Kos Koshnaw adds.

It is important to emphasize Neotethys was an old ocean where education began about 250 million years ago and reached the summit about 195 million years ago. What scientists observe today is the traces of the ocean shell of this ocean, which still affects the tectonics of the region, especially in the interaction between Arabica and Eurasian plates.

For millions of years, the oceans have been transformations that shaped the surface of the planet. This process can lead to the emergence of new continents and even the disappearance of all seas.
