Richat Structure, Rock formation in Adrar Plateau, Mauritania
The Richat Structure spans 40 kilometers in diameter with concentric rings of exposed sedimentary rock layers in different colors and textures.
French explorer Theodore Monod first documented this geological formation in the 1930s, leading to decades of scientific research and geological expeditions.
Local inhabitants named the structure 'tagense' after the circular opening of traditional leather water pouches used at desert wells.
The nearest settlement is Ouadane, and visitors require desert-equipped vehicles, navigation tools, and substantial water supplies to reach the location.
The structure contains a central megabreccia core surrounded by alternating bands of quartzite, limestone, and various crystalline rocks.
