Rocks From Space... How cool is that?
Your meteorite is part of a group of iron meteorites that come from Campo del Cielo. Campo del Cielo, Spanish for “Field of the Sky,” is in the far north of present day Argentina, 1,000 kilometers northwest of Buenos Aires. It is approximately 4.5 billion-years-old.
The crater field covers an area spanning 3 kilometers by 20 kilometers, with at least 26 distinct craters. While the initial impact of the meteorite, which struck earth 4,000 to 5,000 years ago, created Campo del Cielo, smaller meteorites are found as far away as 60 kilometers from the main crater site. Each of the craters contains iron masses – some of them are among the largest ever discovered.
Since the 1500’s many large meteorites have been discovered, the largest being over 37 tons – the second largest meteorite ever identified. Because of the many unusually large meteorites discovered, it is theorized that the original meteorite that breached the earth’s atmosphere fractured into several large segments which then impacted the earth’s surface, creating a debris field that still renders meteorite fragments of all sizes. It is estimated that the original meteorite may have been as large as 4 meters in diameter.
What were once trees and other vegetation have been found under meteorite fragments in the form of charred wood. Carbon-14 tests reveal that the Campo del Cielo meteorite fell around 4,200–4,700 years ago, or 2,200–2,700 years BC.
