This paper briefly and critically discusses several common geobarometers applied to granitic systems, especially the specific rock types, and their limitation and error analysis. The Al-in-hornblende barometer can be applied to calc-alkaline granites and is suitable for low-pressure mineralized granitic pluton. The Fe-rich orthopyroxene-fayalite-quartz assemblage barometer can be used to calculate the crystallization pressure condition of rapakivi granites, and the crystallization pressure of coexisting alkali feldspar, plagioclase and quartz can be obtained via projecting onto the Q-Ab-Or-H2O phase diagram for granites. The hydrostatic pressure of fluid inclusion in granites can be acquired by thermodynamic state equations or Raman spectroscopy.
