Meteorite impactite glass is formed when a large meteorite strikes the earth at such force as to shock and melt the immediate surface area, and then ejects the material from the crater. Henbury impactite is a glassy material full of vesicles and contains a small amount of nickel-iron metal. Henbury impactite material is exceedingly rare and scarcely available to collectors.
Tthe Henbury iron meteorite crater-forming event took place about 5000 years ago. The craters were first discovered in 1931 in the Northern Territory of Australia. A huge meteor entered earth’s atmosphere and broke apart into thousands of pieces, 12 of which were large enough to create meteorite impact craters.
