Structural and Magnetic Phase Transitions in MineralsThis volume in Advances in Physical Geochemistry presents the latest synthesis of theory and experimental data pertaining to structural and magnetic phase transitions in a variety of geochemically important minerals. The book is the first to cover the impact of this rapidly progressing area of solid state physics in earth sciences and reflects its growing significance for mineralogy and petrology. |

This compositional restriction appears to be structurally controlled : Ca has been
found only in the larger M2 site , while Fe and Mg substitute in both M1 and M2
sites . Binary olivines have been synthesized with Ca : Fe ratios greater than one
...

The olivine structure is a framework from the point of view of the metal ions .
There are chains of edge - sharing octahedral M1 sites ( point symmetry 1 )
running parallel to b that are connected to sheets of corner - sharing octahedral
M2 sites ...

In an extension to ( Fez- , Mn , } [ Siz ] 04 solid solutions it was found that the
direction of sublattice magnetization is cor b , depending on the occupancy of M1
or M2 sites by Fez ( Ballet et al . , 1987 ) . The iron - deficient ferrous - ferric
