Minerological Crystallography: V. Oxides and Hydroxides

Abstract

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.
