1300. Area code. 013. Website. [1] Barberton is a town in the Mpumalanga province of South Africa, which has its origin in the 1880s gold rush in the region. It is situated in the De Kaap Valley and is fringed by the Makhonjwa Mountains. It is 43 kilometres (27 mi) south of Mbombela and 360 kilometres (220 mi) east of Johannesburg . Barberton ...
Location of the Barberton Greenstone Belt. The Barberton Greenstone Belt is situated on the eastern edge of the Kaapvaal Craton in South Africa. It is known for its gold mineralisation and for its komatiites, an unusual type of ultramafic volcanic rock named after the Komati River that flows through the belt. Some of the oldest exposed rocks on ...
The Barberton Greenstone Belt of eastern South Africa contains some of the most widely accepted fossil evidence for Archean life. These cell -sized prokaryote fossils are seen in the Barberton fossil record in rocks as old as 3.5 billion years. [1] The Barberton Greenstone Belt is an excellent place to study the Archean Earth due to exposed ...
The Barberton greenstone belt (BGB) is located in the Kapvaal craton of southeastern Africa. It characterizes one of the most well-preserved and oldest pieces of continental crust today by containing rocks in the Barberton Granite Greenstone Terrain (3.55–3.22 Ga ). The BGB is a small, cusp-shaped succession of volcanic and sedimentary rocks ...
The Vredefort impact structure is the largest verified impact structure on Earth. [ 1] The crater, which has since been eroded away, has been estimated at 170–300 kilometres (110–190 mi) across when it was formed. [ 2][ 3] The remaining structure, comprising the deformed underlying bedrock, is located in present-day Free State province of ...

Onverwacht Group. Pha. Had. / -25.8; 31.0. The Onverwacht Group or Onverwacht Series is a series of greenstone belts and volcanic rock formations from the Archean Eon in the Kaapvaal Craton in South Africa and Eswatini . A well known part of the Onverwacht Series is visible in the Komati valley, located in the east of the Transvaal region.
The craton is a mixture of early Archean (3.0–3.5 Ga) granite greenstone terranes and older tonalitic gneisses (ca. 3.6–3.7 Ga), intruded by a variety of granitic plutons (3.3–3.0 Ga). Subsequent evolution of the Kaapvaal Craton (3.0–2.7 Ga) is thought to be associated with continent–arc collision that caused an overlaying succession ...
