Some 4,700 years ago a metal-rich asteroid impacted in the central Australian desert of the Northern Territory, leaving the area scarred with 12 impact craters. Today, the Henbury Meteorites Conservation Reserve can still be visited. Interestingly, the Henbury impact might have been observed and it occurs in the oral tradition of the Aboriginals (read more). Meteorite fragments are still found in the area and are named after a nearby kettle station. The iron meteorites are composed of Fe-Ni metal that crystallized from a melt. Their structural classification places them among the Medium Octahedrites, while they fall within the chemical group IIIAB. More extensive background on the Henbury and its crater field can be found in this book.
