The oldest oceanic crust is then subducted and reassimilated in the mantle. These events explain why oceanic crust is not as old as many continental rocks. Once cooled, the new crust is broken in half along the rift valley, each half moving away from the rift as new crust is formed. The oldest ocean crust is only about 150 to 200 million years old.
