(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.

Researchers found a notable effect of aluminum on the sound velocities of superhydrous phase B, a dense hydrous magnesium silicate and potential host of water in the deep Earth. Their results suggest ...

(a, b) Images show deformation cell assemblage and microstructure of shear-deformed Al bearing-phase D aggregate under 20GPa, 800°C, conditions of lower mantle transition zone. Large deviation of ...

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 ...

Add Yahoo as a preferred source to see more of our stories on Google. New experiments show Earth’s lower mantle trapped far more early water than thought, reshaping views of habitability. (CREDIT: ...
