Tuttle and Bowen studied in 1950 high temperature feldspars.
Yoder performed in 1952 the experimental demonstration of Clapeyron’s equation for the fusion of diopside under changes of pressure.
Krumbein and Garrels applied in 1952 Eh versus pH diagrams to the equilibrium of minerals in aqueous phase.
