Nature research paper: Variation in bridgmanite grain size accounts for the mid-mantle viscosity jump
). The capsules were loaded into the 7/3 multi-anvil cell assemblies and compressed to 27 GPa, followed by heating at 2,200 K for 1.5–1,000 min . Because of the relatively fast heating and cooling speeds , the growth during heating and cooling is negligible.
The recovered samples were separated from CsCl by dissolution in water, polished and observed using a scanning electron microscope with acceleration voltages of 5–20 kV. Bridgmanite and ferropericlase grains were distinguished by the brightness contrast in backscattered electron images . The volume fraction of ferropericlase was obtained from the BSE images. The area of each bridgmanite grain was determined using an image processing software .
