Gweni-Fada crater

Gweni-Fada is a meteorite crater in the Ennedi Plateau, Chad.

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.

Centered at 17°25′N and 21°45′E, being slightly wider in the NW-SE direction, the asymmetric structure is deeply eroded. A broad depression forms a crescent around two thirds of the inner complex zone. On the northern side, an elevated outer ring of outward-dipping sandstones surrounds the depression.
