The Mediterranean Sea is home to what could be the world's oldest oceanic crust, an undisturbed section of Earth's outermost shell that scientists say is about 340 million years old. Most oceanic crust is less than 200 million years old, because it is typically recycled back into the Earth's mantle at subduction zones (where two tectonic plates collide). In the new study, researchers used magnetic sensing equipment to profile areasof the eastern Mediterranean.
