Oldest Rocks On Earth. The oldest rocks are found in the cores of continents, and the youngest are in the rift valleys of mid-ocean ridges. they can be found at the tops of mountain ranges as well. some of the oldest rocks found on Earth can be found at the top of the Beartooth mountain range here in MT. Atlantic ocean.
The oldest continental rocks are found in what we call cratons. A craton is a stable part of the continental lithosphere, which has survived several cycles responsible for the merge and the dislocation of supercontinents. Cratons are therefore always found within continents. Some cratons in Canada and Greenland shelter the oldest continental rocks in the world, about 4 billion years old. Other cratons in South Africa, Australia and Asia have 3 billion years old continental rocks. The oldest seafloor is comparatively very young: about 280 million years old. It is found in the Mediterranean Sea and is a remnant of an ancient ocean that is disappearing between Africa and Europe.
