Confirmed impact structures

Locations of confirmed impact craters in Africa, maximum ages:
Cenozoic
Mesozoic
Paleozoic
Precambrian

This list of impact structures in Africa includes all 20 confirmed impact craters as listed in the Earth Impact Database. These features were caused by the collision of large meteorites or comets with the Earth. For eroded or buried craters, the stated diameter typically refers to an estimate of original rim diameter, and may not correspond to present surface features.

Unconfirmed impact structures

Main article: List of possible impact structures on Earth

The following craters are officially considered "unconfirmed" because they are not listed in the Earth Impact Database. Due to stringent requirements regarding evidence and peer-reviewed publication, newly discovered craters or those with difficulty collecting evidence generally are known for some time before becoming listed. However, entries on the unconfirmed list could still have an impact origin disproven.

Name	Location	Diameter	Age	Coordinates
Kebira	Gilf Kebir region, Egypt	31 km	100 million	24°40′N 24°58′E
Temimichat[2]	Mauritania	0.75 km	unknown	24°15′N 9°39′W
Wembo-Nyama ring structure[3][4]	DR Congo	36–46 km (est.)	60 million	3°37′52″S 24°31′07″E
Mahas1[5]	Northern, Sudan	2.85 km	Unknown	20°01′53″N 30°13′48″E
Circular feature with clear ca. rim 300 m above ground level centred around the hamlet of Baw	Blue Nile State	5 km	Unknown	11°20′00″N 30°03′00″E
Circular Feature [6]	North-Central Niger	10 km	Unknown	21°21′14.56″N 9° 8′32.24″E
Vélingara circular structure[7]	Kolda Region, Senegal	48 km	Unknown	13°00′00″N 14°08′00″W

Notes

¹Mahas was anonymously added Jan 2015, but the coordinates do show a convincing impact-like structure.
