Barberton Greenstone Belt
The Barberton greenstone belt in South Africa is one of the best-preserved successions of mid-Archean (3.57–3.21 Ga) supracrustal rocks in the world, together with the Pilbara Craton in Western Australia. As such, it is a remarkable natural laboratory where conditions and processes at the surface of the Archean Earth can be studied in detail.
