43 olivine phase diagram
The phase diagram of olivine and the seismological discontinuities The experimental study of the phase diagram of olivine shows the existence of several phase transitions and a decomposition of this mineral around 24 GPa. The correspondance between these observations confirms the hypothesis of an upper mantle mainly composed of olivine. Eutectic and Peritectic Systems T-X phase diagram of the system Fo-Silica at 0.1 MPa. After Bowen and Anderson (1914) and Grieg (1927). Amer. J. Sci. i = "peritectic" point At 1557oC there is colinear equilibrium of Fo-En-liq!geometry indicates a reaction: Fo + liq = En!consumes olivine (and liquid) →resorbed textures When is the reaction finished? cc d i k m Fo En 1557 ...
