GEOCLASSICS - Campo del Cielo

The site was first discovered by the Spanish in 1576 in the Gran Chaco Gualamba region of Argentina.
Radio carbon dating of chared wood from the craters, combined with the oral history of the indigenous people, place dates on the meteorites between 4000 and 6000 years.
These meteorites are approximately 92% iron, but also contain small amounts of nickel, cobalt, phosphorus, gallium, germanium, and iridium.
