The new model of the Earth's mantle and crust from Sandia National Laboratories and Los Alamos National Laboratory is called Sandia-Los Alamos 3D, or SALSA3D.

A study reveals that the oldest continental crust on Earth is slowly being broken up by shifting tectonic forces.

The model shows mantle plumes (where the hot rock flows) starting at the bottom of the core-to-mantle boundary and climbing to the top, where they connect to volcanic hotspots in the Earth's crust.

Some areas of continental crust have maintained long-term stability from the beginning of Earth's history, ... (a technique that uses seismic waves to generate 3D models of Earth's interior). ...

Feng explains that these models incorporate information from seismic waves, gravity measurements, magnetic fields, and other geophysical observations to create detailed 3D representations of the ...

Geologists have made certain assumptions about how the crust making up our planet's earliest surface formed, but a new study has found that Earth's very first protocrust was surprisingly similar ...

Beneath the American Midwest, on the continent of North America, the underside of Earth's crust is dripping into the planetary interior. There, blobs of molten rock are coalescing in the upper ...

"The stony asteroid would have opened up a hole probably almost the thickness of Earth's crust, almost 30 km [18 miles] deep, and on the order of 80 to 100 km [50 to 62 miles] wide." ...
