Richat structure. 3-D satellite image of the Richat structure,Maur Adrar Desert,central Mauritania,Africa. It was produced using GeoMapApp,a geophysical visualisation program at the Lamont-Doherty Earth Observatory of Columbia University,USA,using data from the Shuttle Radar Topographic Mission (SRTM). This bullseye structure is almost 50 kilometres in diameter and,contrary to its appearance,is not an impact crater but is most probably a natural rock formation | |
