Resembling an enormous bull’s eye, the Eye of the Sahara, also known as Richat Structure is an immense and puzzling geologic arrangement that predates the appearance of life on earth.
For centuries, the Eye of the Sahara had been stowing away from the sight of humans and the visibility of this staggering bulls-eye in the sand was confirmed by the astronauts. Many of the geologists believe that it started to form when the super-continent Pangea started to fall apart.
The In-depth Reasearch
Even after the discovery, there have questions lurking around this whole structure and the researchers are still trying to find the answers. Situated in the western Sahara Desert in Mauritania, it is said that the Richat Structure is considered as a heaven for astronauts.
When the Gemini IV mission of a four-day circle around Earth was taking place in 1965, the space explorers were solicited to take photographs from Earth’s terrain. They were especially approached to pay special attention to the details of “any enormous round highlights which may be the foundations of effect structures,” as indicated by the content going with a lot of photos distributed from the mission.
Craters are of geographical significance enlightened us with the theories regarding the historical backdrop of the Earth. Additionally, they came up with the proof of how frequently space rocks have collided with our planet which assisted the researchers in estimating what’s yet to come. In the beginning, researchers thought that the Eye of the Sahara was an impact crater. In any case, they didn’t discover enough evidence to drive their speculation on the right track. Current speculations recommend a considerably more entangled story behind this amazingly formed structure. The primary ring structure of the Eye is considered to be the past layers of the earth which were once the lofty dome

Researchers still have inquiries concerning the Eye of the Sahara and the more they delve deeper into it, the more answers they find. After doing the case study, two Canadian geologists managed to find an answer about its beginnings. They believe that the Eye’s formation started 100 million years ago, even before the existence of life on Earth. The super-continent Pangaea was torn separated by plate tectonics and when it broke the water of the Atlantic Ocean began to flow in the region. Liquid rocks were pushed up towards the surface however didn’t make it the whole distance, making a vault of rock layers, similar to a huge pimple.
This additionally made separation points orbiting the Eye and its intersections. The liquid rock additionally broke up limestone close to the center of the eye, which fallen to shape an extraordinary sort of rock called Breccia.
After the phenomena, the Eye had a violent eruption which cleared the bubble shape structure, and erosion wrapped up the work to make the Eye we know today. The rings are made of various sorts of rocks that disintegrate at various speeds. The circle close to the center point of the Eye is volcanic rock made during that blast. The newbie astronauts are surprised by the Eye because such an extensive amount the Sahara Desert is a whole ocean of sand. The Eye is one of only a handful couple of breaks in the monotony, and now it’s turned into a key milestone for the researchers.
The Unique Structure
Researchers flock to the Eye to study its unique geographical Richat Structure which introduces a rich store of molten rocks like rhyolite, kimberlite, gabbros, and carbonatite. Three settled rings look like cuestas (a slope or edge with a delicate incline) plunge outwards from the Richat structure. Towards the center of the land structure, a limestone-dolomite rack encases a siliceous, lenticular-molded breccia that is infiltrated by different interruptions of basalt, kimberlite and volcanic rocks. The Richat Structure likewise has terrific thermal modifications to water particles as a feature of the structure.
Threats for Human life
Due to climate change, desertification has increased which could lead to the approach of sand dunes towards the rocky bed leading to the burial of desert sand in the future. The Richat Structure is of little risk from anthropogenic activities since it is situated amidst deserted natural surroundings. Scarcely any roaming tribes and little permanent residence in the bunch of close by towns are the main types of human home in the territory. The extraordinary bone-dry nature of the place and the high temperatures don’t support human settlements in the territory however some iron mines exist in the close by territories.
Even after great researches, only a few people could believe that the Eye of the Sahara is remnant of the city of Atlantis, which Plato depicted as concentric rings of water and land. The geographical history of the structure uncovers many intriguing facts. Some even believe that this structure was formed when an alien ship landed here. They believe that the aliens were the first to invade earth and made much modification to nature and ecosystems on the Earth. But still, the alien theory could not be neglected as long time in the history their presence on earth has been explained. So even after multiple theories and explained philosophies, this structure still remains a mystery!
