Thanks to an alien-looking mineral, scientists have determined that part of Earth's mantle -- which constitutes about 84% of our planet's volume -- is melting, indicating the presence of vast ...

Earth's mantle and its core mix at 2900 kilometers under our feet in a mysterious zone. A team of geophysicists has just verified that the partial fusion of the mantle is possible in this area ...

The relations between the mantle temperature, the amount of decompression and the degree of partial melting, together with the solid–liquid partition coefficient for many chemical elements, have ...

Learn about how volcanoes are formed and the ways they erupt Chiara Maria Petrone, Roberto Scandone, and Alex Whittaker On ...

These results suggest the existence of a process recycling marine carbon into Earth's mantle, which could contribute to regulating the global carbon cycle and maintaining conditions favorable for life ...

A joint study between Carnegie and the Woods Hole Oceanographic Institution has determined that the average temperature of Earth's mantle beneath ocean basins is about 110 degrees Fahrenheit (60 ...

New research has dramatically reshaped our understanding of Earth’s early geological history, overturning traditional beliefs ...

New research from HKU geologists suggests that Earth's first continents were born not from plate tectonics, but from deep ...

In the early 1960s, geologists conceived of an idea to reach Earth’s mantle via Project MoHole, an effort to drill through Earth’s crust to obtain samples of the Mohorovičić discontinuity, or Moho -- ...

Although this is the deepest into the mantle scientists have ever drilled, the mission didn’t uncover pristine mantle that lies beyond the Mohorovičić discontinuity, or Moho, boundary.
