A team of researchers from the U.S., China and Canada has found evidence in diamonds of free-flowing water in the boundary between Earth's upper and lower mantle. In their paper published in the journal Science, the group ...
Research from the University of Texas at Arlington and the Wadia Institute of Himalayan Geology suggests that hydrogen, oxygen, water and carbon dioxide are being generated in the earth's mantle hundreds of kilometers below ...

Earth's mantle is a solid layer that undergoes slow, continuous convective motion. But how do these rocks deform, thus making such motion possible, given that minerals such as olivine (the main constituent of the upper mantle) ...
