The Vredefort Dome, located 120 km SW of Johannesburg, is the deeply-eroded remnant of the central portion of the world’s largest (original diameter >250 km) and oldest (2.02 Ga) impact structure. The deep levels of erosion, estimated at between 8 and 10 km, allow unprecedented access to the roots beneath a giant impact structure. The Vredefort Dome also presents an on-edge profile through more than 25 km of Archaean to Palaeoproterozoic crust of the Kaapvaal craton, spanning one-third of Earth’s history.
Roger Gibson is an internationally-acknowledged expert on the Vredefort Dome who has authored both a popular book on the Vredefort impact event (currently being revised for a 4th edition) and two scientific guides to the Dome. He has published more than 40 scientific papers related to the impact event and geology of the Dome.
A variety of sites will be visited that showcase the principal impact features, including shatter cones, pseudotachylitic and impact melt breccias, extreme thermal effects, and impact-induced folds and faults, as well as the beautifully-exposed on-edge profile through the Archaean basement complex and Witwatersrand Supergroup.
