WASHINGTON, Aug 8 (Reuters) - 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 - ...

Scientists have drilled a hole thousands of feet beneath the floor of the North Atlantic Ocean and extracted rocks from Earth’s mantle. It’s the deepest hole ever dug to collect mantle rock, according ...

Scientists have recovered the first long section of rocks that originated in the Earth's mantle, the layer below the crust and the planet's largest component. The rocks will help unravel the mantle's ...

Earthquakes are fracturing solid rock nearly 90 kilometers beneath stable continental interiors, a depth where standard geophysics holds that mantle material should deform by slow, plastic flow rather ...

If you were to slice through it, you would see the Earth is divided into distinct layers. On top is the relatively thin crust where we live. Beneath that is the 2,900 km thick mantle layer. Then, ...

The researchers say the rocks recovered from the mantle bear a closer resemblance to those that were present on early Earth rather than the more common rocks that make up our continents today.
