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.

Darwin Glass
"Impact Glass"
Mount Darwin Crater - Tasmania
The Mount Darwin crater is approximately 770,000 years old and has a diameter of 1 km.
Darwin Crater lies in an inaccessible area 26 km to the south of Queenstown Tasmania. Although natural glasses have been found by indigenous people in the Mt. Darwin area for a long time, the crater itself was only discovered in 1972. A particularly luxuriant vegetation and the mountainous aspect of the area, prevented the discovery of the crater and of greater quantities of glass. First analyses were performed by Suess F.E. in 1914.
