This is a specimen of Darwin Glass from Tasmania , Australia . Darwin glass is an impactite—the result of a meteorite impact. The awesome power of the extraterrestrial visitor striking the Earth melted the ground turning it into molten glass and sending it flying in a giant splash. The molten material, twisting and turning through the air, cooled and hardened, landing sometimes miles away from the point of impact. The first documented piece of Darwin Glass was discovered in 1915 but the source was not found at the time. The crater was eventually discovered in 1972, 5 miles from where the first specimen was collected. Darwin crater is 5 miles south of Mt. Darwin in heavy vegetation, an environment that helped conceal its whereabouts for so many years. The crater is 3281 feet across and 656 feet deep. While Darwin glass is classified an impact rock from a meteorite, many people cannot miss the fact that its age, roughly 700,000—800,000 years old, is virtually the same as for the Australasian Tektites, and suspect that the same event created both. Certainly there are some differences, but it may be from an asteroid, or comet, that struck Earth in pieces, with one of the smaller pieces causing the Darwin crater and its molten Darwin Glass material, while another larger chunk (or chunks) may have been responsible for ejecting material read more
