Figure 11
Variation of the polyhedral volume of the M2 and M1 octahedra as a function of 〈M—O〉. The dashed lines are guides to the eye. Key: red diamonds represent the M2O6 polyhedral volume for OPX; blue diamonds the M2O6 polyhedral volume for PPX, PEN and LiFe3+Si2O6Cpx; red squares the M1O6 polyhedral volume for OPX; blue squares the M1O6 polyhedral volume for PPX, PEN and LiFe3+Si2O6. Cpx = clinopyroxene. |
