The composition of the mantle transition region, characterized by anomalous seismic-wave velocity and density changes at depths of approximately 400 to 700 km, has remained controversial. Some have proposed that the mantle transition region has an olivine-rich 'pyrolite' composition, whereas others ha...

The posterior mantle edge region of the Mediterranean mussel was collected and washed in culture medium. The composition of the culture medium was as described in91(30% L15 medium (Sigma) and 70% SW) but the sea water used was collected from the mussels natural environment, filtered (0.22 ...
The constitution of the lunar middle mantle, which is located between two prominent discontinuities at depths of 270 and 500 km, has been investigated by a method of thermodynamic modeling. On the basis of the THERMOSEISM data base, self-consistent phase equilibrium assemblages and synthetic seismic...
stony-irons, which probably originate in regions between a metal core and a stony mantle; and some stones that are composed of mantle or crust material from their differentiated parent bodies. For information on the earliest history of the solar system, we turn to the primitive meteorites—those...

In contrast, melt inclusions (MIs), pockets of melts trapped within crystals growing at depth, are shielded from subsequent mixing and contamination of the magmas on their way to the surface, and may thus provide a more direct picture of the composition of the mantle below the crust3,4,5,...
