This study evaluates uncertainty in pressure difference of empirical geobarometers derived from thermodynamic properties, which is expressed as: The uncertainty is independent of enthalpy and its uncertainty, and increases mainly with increasing temperature difference. Examination of several empirical geobaromters reveals that the uncertainty in pressure difference is smaller than that in pressure estimation by a factor of at least one third within the temperature range of almost every single metamorphic complex.
