New study suggests gigantic masses in Earth’s mantle untouched for more than 4 billion years
Ancient, distinct, continent-sized regions of rocks, isolated since before the collision that created the Moon 4.5 billion years ago, exist hundreds of miles below the Earth’s crust, offering a window into the building blocks of our planet, according to new research.

The Ionian basin – a patch of seafloor under the Mediterranean – is the oldest-known section of the seabed to have remained static, held by irregular-shaped continental joints that prevent its motion. The Ionian Sea carries its years well – scientists have debated its true …
