Darwin glass is a natural glass found south of Queenstown in West Coast, Tasmania. It takes its name from Mount Darwin in the West Coast Range, where it was first reported, and later gave its name to Darwin Crater, a probable impact crater, and the inferred source of the glass. The glass is an impactite resulting from the melting of local rocks due to the impact of a large meteorite. This Tektite glass is slightly translucent with a greenish tint. The assumed source is a 1.2-kilometer-wide topographic depression known as Darwin Crater. The crater is filled with 230 m of sediments and breccia. A crater of that size would be created by a meteorite 20 to 50 m in diameter and its impact with Earth would release 20 megatons of energy. filled with 230 m of sediments and breccia.
