Old Gold: An Introduction to Archean Greenstone Belts
2014-10-29 The Abitibi Belt, Canada. The Archean Superior Province of Canada contains the Abitibi greenstone belt, which contains some of the world’s largest gold and copper-zinc deposits with significant amounts of nickel-copper-platinum group element (PGE) mineralization too. Discovered in 1909, the Abitibi has generated over 160 million ounces of gold.

? Gold in the Ancient World
An alluvial gold deposit is a concentration of gold that is put in place by the natural action of the flow of water, where the heavy gold settles out of the moving water, while lighter material like quartz is washed farther downstream. History tells us that gold was the first recycled commodity in civilization. Gold from West Africa, Asia
