Several spelling and typeset errors occurred in the original paper:
(Gottschalk, M. ,1997: Eur. J. Mineral., 9, 175-223):
The following equations are corrected (only typeset errors):
Table 8: The enthalpy of formation from the elements ΔfH° for fayalite determined by Thiery et al. (1981) is -1479.990 kJ.
Table 9: The stoechiometry of leucite, kalsilite and prehnite is K[AlSi2O6], K[AlSiO4] and Ca2Al[AlSi3O10/(OH)2], respectively.
The following changes have been made for the phases:
The heat capacity coefficient f has been changed to the correct value of -18.5232 10-6 .
The molar volume has been changed to 127.82 cm3 (Krupka et al. 1979).
The reactions and 1/T - ln Kred plots involving pyrophyllite have been recalculated.
The enthalpy of formation from the elements ΔfH° has been changed to 8245.264 kJ.
