The mechanism facilitating the smooth movement of the oceanic lithosphere over the underlying asthenosphere (upper mantle) remains poorly understood. Recently, researchers from Japan investigated the ...
A record-breaking drilling attempt, which dug more than a kilometer into an underwater mountain in the Atlantic Ocean, has given scientists a treasure trove of rocks to study for clues to Earth's ...

Mantle 'chemical patchiness': Study provides first direct evidence of its spatial scale
A joint research group has identified that the spatial scale of "heterogeneity" in the upper mantle, caused by a large-scale flow called a mantle plume rising from deep Earth, is less than 10 ...
Scientists have identified a previously unknown layer of partially molten rock hidden below the Earth’s crust — one that may help settle a long-standing puzzle about how tectonic plates move. The ...
The upper plane is the three-dimensional visualizations of the S-wave velocity model, and points mark the ages of exposed post-collisional magmatic rocks. The lower plane is the geodynamic ...
Unsustainable irrigation and drought have emptied nearly all of the Aral Sea’s water since the 1960s, causing changes extending all the way down to Earth’s upper mantle, the layer beneath the planet’s ...
