Aouelloul Glass
The Adrar Desert of Mauritania in the West Sahara is home to a typical flat bowl shaped crater about 350 meters across. Impact glasses were first described by Campbell-Smith W. and Hey M.H. in 1952. Aouelloul glass resembles Darwin glass and is made of small, black, inhomogeneous, irregularly shaped glass chunks. The glass was found to contain lots of schlieren and half-disintegrated minerals when first analyses were conducted in 1966. The age of these impact glasses is estimated at 3.25 million years.
