Taking place on: 6 - 12 September 2014
The Barberton granitoid-greenstone terrain in South Africa represents a classic site of Archaean geology in which the nature and processes of early Earth history may be investigated. Many issues pertaining to Archaean geology, such as crust-forming processes, geodynamics, greenstone-hosted gold mineralization, Archaean atmosphere and seawater composition and the origin of life have been extensively studied in this area. The excursion route for this trip will cover prime exposures where the evidence for these processes can be examined. It will also visit drill sites of the ICDP-funded Barberton drilling project. One day of the trip will be to the Kruger National Park situated to the north of the Barberton greenstone belt.
