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 ...
Africa. The Makhonjwa Mountains or Barberton Makhonjwa Mountains are a range of small mountains and hills that covers an area of 120 by 60 kilometres (75 by 37 mi), about 80% in Mpumalanga, a province of South Africa, and the remainder in neighbouring Eswatini.

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 ...

South Africa. Eswatini. Extent. Kaapvaal Craton. Location of the Barberton Greenstone Belt. The Moodies Group is a geological formation in South Africa and Eswatini. [1][2] It has the oldest well-preserved siliciclastic tidal deposits on Earth, where microbial mats flourished. [3]
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 ...
