(a)The phase boundary between stishovite and post-stishovite with the varying Al content. The contour represents the phase boundary of stishovite with different Al content and the H/Al ratio of ~1/3.

An international research team led by Prof. Dr. Tomoo Katsura at the Bavarian Research Institute of Experimental Geochemistry and Geophysics, University of Bayreuth, has discovered why rocks in the ...

For the first time, scientists have directly measured the amount of heat flowing from the molten metal of Earth’s core into a region at the base of the mantle, a process that helps drive both the ...

A new study from a University of Chicago scientist suggests there may be a layer of surprisingly fluid rock ringing the Earth, at the very bottom of the upper mantle. The finding was made by measuring ...

Geologists have discovered how carbon-rich molten rock in the Earth's upper mantle might affect the movement of seismic waves. Geologists from Florida State University's Department of Earth, Ocean and ...

A peer-reviewed study published in Science argues that Yellowstone’s volcanic system owes its heat and magma not to a deep plume rising from near the core-mantle boundary, but to forces generated ...
