Resumen
Se revisan y discuten la termotropía, barotropía e higroscopía del sistema Ca-SO4-H2O y se deriva una representación tridimensional del diagrama de fases del sistema a presión atmosférica. Se concluye que el comportamiento del sistema es un fenómeno termo-hidro-químico acoplado en el cual la actividad del agua es el factor determinante para la existencia de altas concentraciones de Ca2+ y SO2-4 y la presión de confinamiento juega un papel secundario.
