The oldest known rocks on Earth are found in the center of continents. These rocks are typically found in shield areas or cratons, which are stable regions in the Earth's crust that have undergone minimal tectonic activity for billions of years. Some examples of places where the oldest rocks on Earth are found include the Canadian Shield, Western Australia, and parts of South Africa.
