The mantle is Earth's largest layer of rocks. However, because it is covered by at least six kilometers of crust, drilling into it has not generally been possible. The only exception has been ...

Geophysicists have long theorized that the mantle transition zone, wedged between the upper and lower mantle at depths of 410 to 660 kilometers, could be a secret vault for Earth’s lost water.

Geoscientists have made an unprecedented achievement on their 60-year quest to know more about Earth's mysterious depths. Pieces of Earth’s rocky mantle were collected by a drilling vessel ...

Scientists using an ocean drilling vessel have dug the deepest hole ever in rock from Earth's mantle - penetrating 4,160 feet (1,268 meters) below the Atlantic seabed - and obtained a large sample ...
