The oldest crust on earth can be found in Australia and parts of Canada. It ranges in age from 3. 7 to 4. 28 billion years old. Australia holds the oldest continental crust on Earth, researchers have confirmed, hills some 4.4 billion years old. The oldest patch of undisturbed oceanic crust on Earth may lie deep beneath the eastern Mediterranean Sea and at about 340 million years old, it beats the previous record by more than 100 million years. 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 The oldest oceanic crust is about 260 million years old. This sounds old, but is actually very young compared to the oldest continental rocks, which are 4 billion years old. Scientists Uncover Insights Into the Formation of Earths Oldest Continental Crust.

We will write a cheap essay sample on "How old is the oldest oceanic crust (Atlantic, Pacific, and Indian)?" For the first time, we can say something about what kind of rock was a precursor to the first continental crust, says study coauthor Jonathan ONeil, a geochemist at the University of Ottawa.
