MgO-Al2O3-SiO2
New end-members in this subsystem are the sapphirines, gedrite, sudoite and osumilites. The sapphirine end-members 442-sapphirine and 793-sapphirine have been added to the data set using the experiments of Chatterjee & Schreyer (1972), Hensen (1972), Ackermand et al. (1975), Doroshev & Malinovskiy (1974), Seifert (1974) and Newton (pers. com. 1989). At present the sapphirine data are not consistent with all the experiments in the MASH subsystem, most notably with the quartz-saturated assemblages. It may be that order-disorder behaviour in sapphirines will need accounting for before agreement is complete. Because no data exist for the composition of sapphirine at the end of the experimental runs, an ideal mixing on sites model involving the two sapphirine end-members was used with an iterative approach to generate the equilibrium composition of sapphirine for each experiment. Thus the sapphirine data are to be treated as provisional. Preliminary data for Na-free aluminous gedrite have been added using the experimental data of Schreyer & Seifert (1969), and for sudoite using the data of Vidal et al. (1992) and Fransolet & Schreyer (1984).
Al contents of talc from the reversal experiments of Hoschek (1995) were used to refine the enthalpy of the tschermak's talc end-member. Magnesium staurolite data are now more reliable than in HP90 for two reasons. First, the entropy of Mg-staurolite in HP90 was in error and has now been corrected to the value from the entropy estimation model of Holland (1989). Secondly, the enthalpies are now extracted from the better documented high-pressure experiments of Massonne (1995) and Chopin & Sobolev (1995). The cordierite-H2O model now incorporates the experimental data of Skippen & Gunter (1996), and uses the measured Cp of Carey (1993) for hydrous cordierite (hcrd) and the calorimetric measurements on cordierite hydration enthalpy from Carey & Navrotsky (1992).
The revised heat capacity model for spinel, taken as an oxide sum with a non-convergent Landau excess added, using the results of Carpenter & Salje (1994a), has made it possible to satisfy the recent palladium solubility measurements of Chamberlin et al. (1995) as well as the high-pressure phase equilibria.
As a workable approximation, aluminous orthopyroxenes were modelled as ideal solutions of enstatite and Mg-tschermak's pyroxene; a(en) = X(en), a(mgts) = X(mgts).
Data for the osumilite end-members have been added, following the study of Holland et al. (1996). In this study the enthalpies are retrieved entirely from the experimental results of Carrington & Harley (1995), using the mixing model given in Holland et al. (1996a).
