The oldest rocks on Earth are typically found in the center of continents. More specifically, areas known as cratons or shields, which are stable portions of the continental crust, can contain some of the oldest known rocks. Examples include the Acasta Gneiss in Canada and the Nuvvuagittuq greenstone belt, which contain some of the oldest dated rocks on Earth.
