Gweni-Fada crater

Gweni-Fada is a meteorite crater in Chad, Africa.The Gweni Fada structure was first noted on the map NE 34 X Fada of the IGN and aerial photographs in the 1950s of IGN by Alain Beauvilain. In April 1995, at the initiative of CNAR a team of French geologists visited the site and reported evidence of shock metamorphism within rock samples they had collected inside the structure.

It is 14 km in diameter and the age is estimated to be less than 345 million years. It is older than that of Aorounga because its coverage of impactite has disappeared as a result of erosion.
