Initial melting temperatures of ice (Te) of fluid inclusions from porphyry type mineralization, range from \(-\)33.0 to \(-\)46.4 \({}^{\circ}\)C. This indicates that, in addition to NaCl, other salts, such as KCl, MgCl\({}_{2}\), and/or CaCl\({}_{2}\), are dissolved in the fluid [55]. The final ice melting temperatures (Tm) of the Type 1 inclusions range between \(-\)19.4 and \(-\)10.8 \({}^{\circ}\)C, indicating a moderate to relatively high salinity of 14.8 to 22 wt.% NaCl equiv. [56]. In type 3 fluid inclusions, Tm range from \(-\)16.5 to \(-\)12 \({}^{\circ}\)C demonstrating moderate to relatively high salinities of 14.4 to 19.8 wt.% NaCl equiv. in the H\({}_{2}\)O-NaCl-KCl system.  
Type 1 inclusions homogenize (Th) from 382\({}^{\circ}\) to 496 \({}^{\circ}\)C (Figure 8, Table 3), while type 2 inclusions homogenize with the disappearance of the vapor bubble after the disappearance of the solid phases (more commonly halite than sylvie). In rare cases, another unidentified solid phase was observed, which is probably a chloride complex of Mg or Ca. Homogenization temperatures in the Type 2 inclusions range from 381\({}^{\circ}\) to 458 \({}^{\circ}\)C (Figure 8, Table 3). Based on the solid phase homogenization temperatures (271-386 \({}^{\circ}\)C) and using the data for the system H\({}_{2}\)O-NaCl [56], the salinity of the type 2 inclusions range from 35.7 to 45.6 wt.% NaCl equiv. Type 3 fluid inclusions homogenize at temperatures from 381\({}^{\circ}\) to 504 \({}^{\circ}\)C (Figure 8). Homogenization temperatures of the fluid inclusions of 1, 2, and 3 types in the porphyry style mineralization overlap between 380\({}^{\circ}\) and 460 \({}^{\circ}\)C, with a distinct maximum at \(\sim\)430 \({}^{\circ}\)C (Figure 8).  
Figure 7: Clusters of fluid inclusions in quartz from the Gerakario porphyry and epithermal deposits. (**a**) Recrystallized quartz grains forming triple junctions with angles at 120\({}^{\circ}\) (white circle) in A-type porphyry vein. (**b**) Fluid inclusions of types 1, 2, and 3, in A-type porphyry vein. (**c**) Liquid-rich inclusions of type 1 in an epithermal stibnite vein. (**d**) Fluid inclusions of type 2 with three solid phases: halite (NaCl), sylvie (KCl), and an unidentified phase, possibly a Ca- or Mg-chloride, A-type porphyry vein. (**e**) Types 2 and 3 fluid inclusions in the porphyry system. Two solid phases, halite (NaCl and sylvie (KCl) are observed in the type 2 inclusion, whereas the type 3 inclusions contain two opaque phases, hematite (Hem and chalcopyrite (Cp)). (**f**) Vapor-rich type 3 inclusions in the porphyry system.  
High-salinity fluid inclusions (type 2) usually coexist with vapor-rich inclusions (type 3) within the same assemblage, demonstrating similar homogenization temperatures (Figures 7b,d and 8). This indicates a simultaneous heterogeneous trapping of two fluids, a saline brine (36-46 wt.% NaCl equiv.) and a low-density vapor-rich fluid with lower salinity (14-22 wt.% NaCl equiv.), which suggests fluids were trapped during boiling [53; 56; 57]. Fluids along the boiling curve do not require pressure correction; therefore, the homogenization temperatures represent the actual trapping temperatures of the fluid [57].  
The initial melting temperatures of ice in the fluid inclusions of the quartz-stibnite epithermal veins vary between \(-\)38.7 and \(-\)49.9 \({}^{\circ}\)C. This indicates that, in addition to NaCl, other salts, such as KCl, MgCl\({}_{2}\), and/or CaCl\({}_{2}\), were involved in the ore-forming fluid [55]. The final ice melting temperatures of the type 1 inclusions range from \(-\)6.9 to \(-\)5.0 \({}^{\circ}\)C indicating relatively low salinities (7.9 to 10.4 wt.% NaCl equiv.) [56]. Homogenization temperatures vary from 256\({}^{\circ}\) to 326 \({}^{\circ}\)C, with a maximum at 290 \({}^{\circ}\)C (Figure 8).
