Thermodynamics is an important tool to interpreting the conditions at which natural geomaterial equilibrate. It allows one to determine, for example, the equilibrium pressures and temperatures and the nature and chemical composition of phases - volved mineralogical and petrological processes. Simple chemical model systems, which are often studied in the laboratory in order to understand more complicated natural systems, generally consist of few chemical components. In order to use phase equilibrium results obtained from model systems for interpreting the con- tions of formation of natural...

Die Bedeutung der Thermodynamik als Mittel zur Interpretation von Beobachtungen an natOrlichen Vorkommen und an synthetischen Proben aus dem Laboratorium kann nicht hoch genug eingeschatzt werden. Experimentelle Ergebnisse mit ihrem Modell charakter kennen nur mit Hilfe dieses Wissenschaftszweiges wirklich sinnvoll genutzt werden. Dieser Sachverhalt spiegelt sich auch in den Fachpublikationen wider. Ohne solide Kenntnisse thermodynamischer Zusammenhange kennen sie kaum oder Ober haupt nicht verstanden werden. Die Studienkommission der Deutschen Mineralogi schen Gesellschaft hat dieser...
