The Kaapvaal Craton is an ancient geological formation in southern Africa, one of the Earth’s oldest and most stable continental cratons, dating back over 3 billion years. It is significant in studying the formation and stabilization of continental crust, as well as in understanding the early history of the Earth’s lithosphere.
