BARBERTON GREENSTONE BELT PDF
Recent field and geochemical studies indicate a need to test the stratigraphy of the ca. Ga Barberton Greenstone Belt as it is presently adopted [1,2]. The principal episodes of the geotectonic history of the Barberton greenstone belt span some Ma from the initial submarine eruption of the Onverwacht laves. The Barberton greenstone belt in South Africa is one of the best-preserved successions of mid-Archean (– Ga) supracrustal rocks in the world, together.

Greensone Belts occur as belts of deformed volcanic and sedimentary strata and get their name from the presence of green minerals Actinolite. The Barberton Greenstone belt is one of the oldest and best exposed Archaean greenstone belts on Earth.
Tectonic evolution of the Barberton greenstone belt
The small and beautiful “Makhonjwa Mountain Range”close to Barberton, where gold and asbestos. These ancient rocks are 3. If you were able to travel back in time to visit Earth during the Archaean period you would not recognize it as the same planet we inhabit today.
It was during this time, that the Earth’s crust cooled enough in order for rocks and continental plates to begin forming.
Tectonic evolution of the Barberton greenstone belt – Wikipedia
The first forms of life appeared on Earth during the early Archaean period. The periods can roughly be divided as follows: The oldest known fossils date back to about 3. All life during the Archaean period was bacterial. Stromatolites, were colonies of photosynthetic bacteria which today have been found as fossils in the early Archaean rocks of Barberton.
Stromatolites were common during the late Archaean age. It was the site of one of the milestones of the industrial development of South Africa. Some of these mines are still producing gold which makes them the oldest gold mines in the world.
For years Barberton has attracted teams of international scientists who return annually to research and interpret the greendtone of the earth’s beginnings and the evolution of life. This is because it is only in the beautifully preserved rocks of the Makhonjwas that they are able to find the clues that science needs to learn about the earth’s earliest history and the way life began. Biologically, this area is home to an incredible variety of endemic native plants and animals occurring only within this particular area in South Africa.
They contain very important high-rainfall mountain catchments which are protected in terms of several proclaimed Nature Reserves. The historic and cultural history of the region is of great importance to the Swazi Nation as well as that of the early colonial era. Its beauty and accessibility makes it a natural destination for barebrton where visitors from southern Africa and overseas can enjoy an inspirational barbdrton educational experience.
Scientists are researching a possible re-dating of when life on earth first occurred. This could possibly be one billion years earlier than greenwtone. Tidal traces billions of years old are so precisely recorded they allow for calculation of changes in the distance between the earth and the moon.
The Barberton Mountainlands is the only place on earth where the development of the early earth crust and evolution of life itself can be greenatone. This can be safely bsrberton to be the place where life on Earth began more than 3. Achaean serpentinites in the Komati river valley, South Africa, have distinctive crystal textures and volcanic features which distinguish them from normal coarse-grained serpentinites.
They are interpreted to represent lava which erupted from the depths of a deep subterranean environment.
