WebGeothermometry Introduction to thermobarometry Geothermometers and geobarometers are mineral systems that may be used to estimate the absolute temperature and pressure that produced an equilibrium mineral assemblage in a metamorphic rock. Thermobarometry, or the determination of temperatures and pressures which WebGeothermometry, based on geochemical analysis, does not reveal elevated temperatures at shallow depths. Such warm springs appear to be associated with deep circulation of meteoric water. Warm springs of the Basin and Range Province of the western United States is one such example.

"WebFeb 1, 1994 · Tools Abstract With the existence of thermodynamic data for a wide range of end-members in rock-forming minerals, thermobarometry now involves combining many equilibria to find the pressure and temperature ( P-T) of formation of a rock. We reiterate that this task need only involve an independent set of reactions representing all these equilibria. " - Geothermometry and geobarometry
