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. |

... between these two ordered states . As shown by Levanyuk and Sannikov (
1976a ) , however , there are some cases where the existence of an inc phase
can be predicted from a knowledge of the symmetry of the high - temperature
phase .

Experiments have shown that the effect of minor components on Di - En phase
relations is dramatic ( e.g. , Gasparik , 1984 ; Lindsley , 1983 ; Mori 1978 ; Perkins
and Newton , 1980 ) . Consequently , simple linear projection schemes ...
