Tungsten (W), a hard, heat-resistant, and corrosion-resistant metal, is indispensable to modern high-tech industries—from ...

Although the mantle is a 2,900km layer of semi-solid rock, it lies at least six kilometers beneath the crust. This makes it nearly impossible to sample. But in 2023, ...

This extreme depth is far greater than any previous attempts to drill into oceanic mantle rocks. According to the study, co-authored by C. Johan Lissenberg from Cardiff University, the scientists ...

For the first time, an international team of scientists recovered a long section of rocks that originated in the Earth’s mantle. This layer just below the crust is the largest part of the planet’s ...

Lin explained that the Atlantis Massif offers researchers a rare opportunity to take samples from the Earth’s mantle, as the Earth has close to a 4.3-mile-thick crust on the seafloor — which means ...

Having access to these mantle rocks will allow us to make the connection between the volcanoes and the ultimate source of their magmas.” [Related: See 24,000 years of climate history at a glance .] ...

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 ...

Although solid, the rocks of the Earth's mantle deform very slowly. Professor Patrick Cordier's team at the Materials and Transformation Unit (Université Lille, France) has developed a model that ...

Gravitational tugs provide an unprecedented peek into the structure of Earth’s mantle and reveal a sudden increase in viscosity roughly 1,000 kilometers below ground.
