Fluid Evolution of Fuzishan Skarn Cu-Mo Deposit from the Edong District in the Middle-Lower Yangtze River Metallogenic Belt of China: Evidence from Petrography, Mineral Assemblages, and Fluid Inclusions

Figure 12

Pressure estimation for fluid inclusions in different stages (NaCl-H₂O system). The green ellipse represents fluid inclusions trapped under first boiling conditions in the prograde skarn stage, while the purple ellipse represents fluid inclusions trapped under second boiling conditions both in retrograde skarn and quartz-sulfide stages. Hence, estimated pressures can be representative of actual trapping pressures for both of them. Particularly, other plotted data represent the minimum trapping pressures. Isobars were calculated from the equations of Driesner and Heinrich [63].
