Archaeologists found in Chile, the production of iron oxide, which is 12,000 years old — the oldest evidence of organized mining operations in North and South America, said "Kompyulenta" referring to an article in the journal Current Anthropology.
A team of researchers led by Diego Salazar of the University of Chile found the 40-meter trench near the coastal town of Taltal in the north of the country. She dug Uentelauken representatives of culture — the first settlers in the region. Iron oxide was they wanted as a pigment for coloring stone and bone tools, and probably clothes and body.
The duration and scope of work shows the amazing technical level, which reached these people. "Production has been labor-intensive activity demanding specific technical skills and a certain social interactions that have been passed down from generation to generation," — says Salazar and his colleagues.
The scientists estimate that the mine was recovered kubichenskih about 700 meters, or 2,000 tons of rock. Radiocarbon dating showed that the development was carried out with approximately 10,000 by the year 8500 BC, then was revived around 2300 BC. Found more than five hundred stone hammers belonging to the first period of use of the mine.
Prior to this finding, the old mines of America was considered a North American copper mine that existed 4 500-2 600 years ago.
