Product Description

Barberton Greenstone Microspherules Makhonjwa Mountains South Africa
The Barberton Greenstone Belt, South Africa, has made its appearance in geological news because of the interesting microspherules found in it. The Makhonjwa Mountains, where this material originates, has come to be known as an area for the "Genesis of Life" primarily because of the extreme age of the rocks and the chronic deformation that has occurred to them. Scientists have found evidence of a large terrestrial impact event near this area, with the evidence of it from the microspherules in this Barberton Greenstone material and other extraterrestrial organic materials dating back to 3.3-billion-year-old volcanic rocks.

This Greenstone Belt gets its name from the presence of its green colored minerals. Minerals such as chromium muscovite "fuchsite", epidote, green chlorite and serpentine are found in abundance. Other Greenstone Belts have been found in Africa, Asia, Europe, North American, South America and parts of Oceania.

The Barberton Greenstone Belt is where gold was first discovered in South Africa. This Belt was first uniquely identified by Prof Annhauser at the University of the Witwatersrand, Johannesburg, South Africa. His work in mapping and detailing the characteristics of the Barberton Greenstone Belt has been used as a guide for other Greenstone Belts around the world.

The Barberton Greenstone Belt, South Africa, has been dated to about 3.3-3.5 Ga. The Makhonjwa Mountain Range has been referred to as the ‘Genesis of Life’, because it's geology includes the best preserved ancient Archean rocks on Earth. It has been interpreted as deposits of Archean seafloor hydrothermal vents. The entire Barberton Greenstone Belt has been subjected to repeated stages of deformation, resulting in folding, faulting and shearing with appreciable deformation and metamorphism linked to successive granitic intrusions.

This Belt has provided an exceptional geological portal for observing the complex geological environments on the early Earth.
