THE RICHAT STRUCTURE
The Eye of the Africa,which is also known as the Richat Structure and Blue Eye of Africa is a popular geological feature.It is said that it resembles a bull’s eye from the sand.
This prominent circular feature is found in the Sahara Desert of Central Mauritania.As by the astronauts,it forms a 50 kilometer wide circular eye formation in the desert.It presents a wide contrast of extrusive and intrusive rocks from shallow to deep source regions which provides an insight to the magmatic process at the origin which sometimes seems like onion shape formation from the above.
The Richard Structure is most oftenly mistaken to a crater which has been now known as the eroded circular structure of layered rocks.At first,scientists thought that a meteorite has been fell on the Earth but now it is believed that due to the uplift of erosio,it has been caused.Also,some believed that the Richat Structure is formed due to the eruption of volcanoes because of the lack of volcanic rocks.But yet,none confirmed the fact of its circularity.It has been a landmark for the astronauts.
The Richard Structure which is located in the Sahara Desert looks featureless from the upper view.Due to this,the astronauts will catch the view of the circular mark which has a diameter of 50 kilometers catch their interest.From the days of space exploration,it has been a remarkable landmark for space people.
Due to its circular feature,the Richat Structure attracted many mainly the scientists and astronauts performing some space missions.Due to this,it has been prominent for shuttle crews. In Richat Structure,many types of erosion was occurred on the various types of rocks which formed ridges.They vary from more erosion resistant rocks which forms high ridges which are in blue and purple colors while the non resistant rock forms which forms valleys which are in yellow color.
Archealogists discovered thousands of floor drawings similar to the blue eye in Syria,Jordan and Saudi Arabia which measures from 82 feet to 230 feet and may be atleast 2,000 years old while some are even older but the mystery between these wheels are still unraveled.
The scientists thought that the reason of symmetrical uplift and the visibility from the space is due to the erosive effects of desert winds.The Richard Structure which generally known as done which consists of symmetrical but curving downward lines called anticlines.These folds consists of alternating layers of three types of rocks called metamorphic,sedimentary and igneous.Due to the formation of anticlines,the older rocks lies in the center of the fold while the younger ones settle surrounding it on the outer side.After millions of years,the dome has been eroded through the hydro thermal water while magma is still near the surface in small quantities.
Even though ,many millions of years passed the exposion to various layers were still there to erosion where the rings formed are made of Paleozoic quartzite which may be of 200 to 500 million years old.
It is said that it is a target for aiming a death ray,laser or any weapon of mass destruction and it looks like it could have been lasered and pinned to the landscape which is totally a natural one.Even though some reasons are still unknown,it attracted the astronauts as it is very much visible from space.
The Richard Structure which lacks its air pressure and brings out moist weather has more impact originated from the surface due to its size.It is different and unique from other extraterrestrial impact structures as it has sedimentary rocks which are in order and they are disoriented and steep.Due to some recent national study on Richat Structure,it is said that it has carbonates within the silica-rich megabreccias which has existed their presence due to its hydro thermal waters in its low temperatures. Also,this structure requires special protection.
The Bull’s Eye is one of the most mysterious work of the mother earth which looks just like a human eye from the space.Even though there is no explanation present for this mystery even after developing many theories from the scientists like some believe it is of meteors and some due to continuous nuclear blasts.It is supposed that there must have been a gigantic range of impact to the earth to form such a wonder in the earth.
The visit to the Richard Structure is increasing day by day as the mystery is attracting tourists worldwide.The view of the structure is really very interesting and nice from the above of the Sahara Desert.As the visit is to the Sahara Desert,the tourist’s main motto is to bring water.Even though it is seen from the distance,the tourists are attracted for its mysterious secret wrapping within itself.The Blue Eye is admired by the visitors all over the world.
