(Phys.org)—A diverse team of researchers with members from Germany, France, Russia and the U.S. has subjected a sample of bridgmanite to conditions believed to be present at Earth's lower mantle and has found that it remained ...
The composition and temperature of the Earth's interior are fundamental for understanding the Earth's interior and dynamics. Because it's impossible to directly access most areas of the Earth's interior, the combination of ...
