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 ...

This buoyant melt rises through the mantle to the surface, where it solidifies and becomes part of the Earth's crust. However, the pathways through which mantle melt migrates have not been well ...

The Earth's mantle and its core mix at 2900 km 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 when ...

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