Bridgmanite was recently named as the most abundant mineral on the Earth. It is mostly found in the lower mantle. It has the general formula (Mg,Fe)SiO3. Its structure is the same as that of perovskites. read more
Bridgmanite was recently named as the most abundant mineral on the Earth. It is mostly found in the lower mantle. It has the general formula (Mg,Fe)SiO3. Its structure is the same as that of perovskites. Perovskites have the general formula ABO3. A represents a large cation and B represents a small cation. read more
Some mineral associations (wüstite + periclase and native iron + iron carbides) are, possibly, related to the D″ layer at the core/mantle boundary.
