THERMOCHEMISTRY OF FORSTERITE-FAYALITE OLIVINE SOLUTIONS

Abstract:

The enthalpies of solution of synthetic Mg2SiO4-Fe2SiO4 olivine solid solutions have been measured in Pb2B2O5 melt at 970 K. The heat of solution of forsterite was found to be 15.62 ± 0.3 kcal mol-1 and that of fayalite 9.39 ± 0.14 kcal mol-1. Solid solutions between these end-members exhibit small positive deviations from mixing ideality, asymmetric towards the Fe end-member. In terms of the sub-regular solution model, excess enthalpies of intermediate olivine are adequately represented by t...
