Origin and Evolution of the Ore-Forming Fluids in the Liyuan Gold Deposit, Central North China Craton: Constraints from Fluid Inclusions and H-O-C Isotopic Compositions

Figure 10

Salinity versus total homogenization temperature plot of the fluid inclusions, showing fluid evolution in the Liyuan gold deposit. Three purple arrows marked as ①, ②, and ③ represent the fluid evolution tendency from early to late stages. The arrows ① and ② mean that the FIs have wider salinities range from early to middle stage due to the fluid immiscibility. The arrow ③ represents that the temperature and salinities both decrease from middle to late stages.
