Fig. 2From: Liquid and supercritical CO2 as an organic solvent in Hadean seafloor hydrothermal systems: implications for prebiotic chemical evolutionEvolution of fluid compositions associated with phase separation caused by a depressurization due to fluid upwelling and b temperature decrease due to fluid mixing (see text for details). Isotherms are enlarged from those in Fig. 1 (Takenouchi and Kennedy 1964). B, V, and M stand for brine, vapor, and mixed phases, respectivelyBack to article page
