Barberton Greenstone Belt | SpringerLink
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.

The Sheba gold mine is located 13 miles N.E. of Barberton, South Africa. Mining started in 1885. The deposit is characterized by hydrothermal, fault/shear-hosted zones of mineralization in the Archean meta-sedimentary rocks of the Barberton Greenstone Belt [1]. However, there is only a little information about the genesis of this famous deposit.

Trace element zoning of sulfides and quartz at Sheba and Fairview gold
Gold in greenschist-facies deposits of the Barberton Greenstone Belt is closely associated with arsenopyrite and pyrite, and is present both as "invisible" gold and as electrum inclusions (Cabri et al., 1989). In this study, we present data on the chemical zoning of sulfides and quartz in mineralised veins from the Sheba and Fairview mines.
