Barberton Greenstone Belt, Mountain range and geological site in Mpumalanga Province, South Africa.
The Barberton Greenstone Belt is a mountain range with volcanic rocks, sedimentary layers, and geological structures stacked one upon another over a substantial vertical distance. The different rock types reveal distinct periods of Earth's development.
The rocks formed between 3.6 and 3.2 billion years ago and document the planet's volcanic activity and early crust development. This timeframe covers some of Earth's oldest known geological phases.
Scientists and students regularly work on-site to study the ancient rocks and understand the processes that shaped the landscape. This ongoing research makes the place a living center for learning about Earth's past.
The region is home to wild animals such as rhinoceros and elephants, so guided expeditions are required for safety. It is important to follow security measures and heed the advice of experienced guides.
Eight distinct layers containing spherical mineral grains record massive meteorite impacts that occurred between 3.5 and 3.2 billion years ago. These impact layers are rare and help scientists better understand the early solar system.
