| Aorounga Impact Crater: Two craters located in the Tibesti Massif in northern Chad have two very different origins. Aorounga is the multi-ringed impact crater at the center of the image. The crater has a diameter of 12.6 km and is estimated to be less than 345 million years old. The impact nature of the crater was confirmed in 1992 when a team of French investigators identified shocked minerals at the site. The grooves running through Aorounga were created by winds that blow around Tibesti. Emi Koussi, the crater on the right, is a Holocene stratovolcano. |
