The Eye of the Sahara, also referred to as the Richat Structure, is a geological phenomenon of significant cultural, historical, and scientific value in Mauritania. The structure emerged over millions of years due to the gradual erosion of rock layers and is visible from space. It holds immense importance for archaeology, given its composition of bimodal tholeiitic and alkaline volcanism dating back to the Cretaceous era. Because of its striking circular shape, the structure remains a subject of considerable scientific inquiry. Its study has contributed significantly to our understanding of plate tectonics and the evolution of the Earth's surface.
