Estimated bt 98.2 – 2.6 Million Years Old: The Blue Eye Of The Sahara, Africa

This strange ancient formation from Mauritania has been dated to have occurred about  98.2 – 2.6 million years ago. This was used by NASA in the earlier stages as a land mark to navigate. The manner of its birth has been hotly contested. The location of this is in Western Africa, bordering the North Atlantic Ocean, between Senegal and Western Sahara. The Blue Eye Of The Sahara has many names, The eye of Africa, The Eye of the Sahara, Guelb er Richat and The Richat Structure.

Initially interpreted as an asteroid impact structure because of its high degree of circularity, it is now argued to be a highly symmetrical and deeply eroded geologic dome. Despite extensive field and laboratory studies, geologists have found a lack of any credible evidence for shock metamorphism or any type of deformation indicative of a hypervelocity extraterrestrial impact.

While coesite, an indicator of shock metamorphism, had initially been reported as being present in rock samples collected from the Richat Structure, further analysis of rock samples concluded that barite had been misidentified as coesite. In addition, the Richat Structure lacks the annular depression that characterizes large extraterrestrial impact structures of this size. Also, it is quite different from large extraterrestrial impact structures in that the sedimentary strata comprising this structure is remarkably intact and “orderly” and lacking in overturned, steeply dipping strata or disoriented blocks.

  A more recent multianalytical study on the Richat megabreccias concluded that carbonates within the silica-rich megabreccias were created by low-temperature hydrothermal waters, and that the structure requires special protection and further investigation of its origin.

This  is a prominent circular feature in the Sahara desert near Ouadane, west–central Mauritania. This structure is a deeply eroded, slightly elliptical, 40 km in diameter dome.

The sedimentary rock exposed in this dome ranges in age from Late Proterozoic within the center of the dome to Ordovician sandstone around its edges. The sedimentary rocks comprising this structure dip outward at 10°–20°. Differential erosion of resistant layers of quartzite has created high-relief circular cuestas. Its center consists of a siliceous breccia covering an area that is at least 30 km in diameter.

Exposed within the interior of the Richat Structure are a variety of intrusive and extrusive igneous rocks. They include rhyolitic volcanic rocks, gabbros, carbonatites and kimberlites. The rhyolitic rocks consist of lava flows and hydrothermally altered tuffaceous rocks that are part of two distinct eruptive centers, which are interpreted to be the eroded remains of twomaars. According to field mapping and aeromagnetic data, the gabbroic rocks form two concentric ring dikes. The inner ring dike is about 20 m in width and lies about 3 km from the center of Richat Structure.

The outer ring dike is about 50 m in width and lies about 7 to 8 km from the center of this structure. Thirty-two carbonatite dikes and sills have been mapped within the Richat Structure. The dikes are generally about 300 m long and typically 1 to 4 m wide. They consist of massive carbonatites that are mostly devoid of vesicles.


The carbonatite rocks have been dated as having cooled between 94 to 104 million years ago. A kimberlitic plug and several sills have been found within the northern part of the Richat Structure. The kimberlite plug has been dated being about 99 million years old. These intrusive igneous rocks are interpreted as indicating the presence of a large alkaline igneous intrusion that currently underlies the Richat Structure and created it by uplifting the overlying rock.

Some people think that this is the lost city of Atlantis.

Plato described the mysterious island as a circular piece, divided into circles of both water and land. According to Plato, there were 3 circles of water and 2 circles of land. He also stated that it was sourounded by rings of mountains.



Spectacular hydrothermal features are a part of the Richat Structure. They include the extensive hydrothermal alteration of rhyolites and gabbros and a central megabreccia created by hydrothermal dissolution and collapse. The siliceous megabreccia is at least 40 m thick in its center to only a few meters thick along its edges.


The breccia consists of fragments of white to dark gray cherty material, quartz-rich sandstone, diagenetic cherty nodules, and stromatolitic limestone and is intensively silicified. The hydrothermal alteration, which created this breccia, has been dated to have occurred about 98.2 ± 2.6 million years ago using the 40Ar/39Ar method.

Why the Eye of Africa is nearly circular remains a mystery.


Two years ago a South African research couple (who wants to remain anonymous) informed Klaus Dona (art curator & archeologist) about “The Eye Of Africa” which has several circle formations. The South African research couple thinks that this is one of the Atlantis cities. Studying the pictures & dvd reel the couple sent him, Mr. Dona asked a friend if he could scan the area, to their surprise his friend found many anomalies. On the higher circles there were destroyed buildings under the earth. Going further inside the circle, bone material and partly precious metals were found. The Atlantic Ocean is 140 Kilometers away from the“The Eye Of Africa”. There are millions of shells in the desert leading to the circle. They think that there must have been a connection with the Atlantic Ocean and “The Eye of Africa”. If so, this puts it back further in history then the general mainstream media feels comfortable saying.
