Representative isochores for minimum and maximum CO₂ densities for H₂O–NaCl–CO₂ inclusions (type I) and the solvus for H₂O–NaCl–CO₂ fluids containing 6 eq. wt% NaCl and 15 mol% CO₂ (after Bowers and Helgeson, [55]). (a) The estimated trapping pressure-temperature diagram of the early stage; (b) the estimated trapping pressure-temperature diagram of the middle stage. Isochores of the type I FIs are calculated using the FLINCOR software.
