The Campo del Cielo iron meteorite fell 4200 – 4700 years ago, about 1000 km northwest of Buenos Aires in Argentina. More than 100 tons of material has been recovered so far.
Campo del Cielo was discovered in 1576 by members of the Spanish military, but the site was already well known to the local Indians before this and they probably used parts of the iron for their weapons. In the following centuries several expeditions were made and recovered most of the meteorites.
Fragments of Campo del Cielo come in a wide range of sizes from small specimens of just a few grams to much rarer big pieces of tens, and sometimes even hundreds, of kilograms.
