Use the lever rule and the MgO-SiO2phase diagram to compute the mass fractions of forsterite and melt produced by incongruent melting of enstatite. Use the albite mole fractions in coexisting melt (Xliq) and solid solution (Xsol) in the albite-anorthite phase diagram to estimate the enthalpy...
In the formula, Δ𝜆𝐵𝜀ΔλBε is the drift of the center wavelength of the reflected light due to the strain, and ε is the change in the external strain. From Equation (2), it can be seen that the center wavelength drift of the reflected light varies linearly with the external...
