Minerological Crystallography: V. Oxides and Hydroxides

The main structure types of the large group of oxide and hydroxide minerals are characterized. A particular attention is paid to the new data on the structural transformations of high-pressure minerals (which are of geophysical interest) occurring in the deep interior of Earth. These minerals include (Fe,Ni) oxides with ilmenite and post-spinel phase structures, silica polymorphs, etc. The crystal structures of basic minerals of the upper mantle, transition zone, and lower mantle, as well as the minerals of iron-manganese concretions, are characterized. The structural principles of the oxides used in ion batteries as cathode materials are considered.
