Fluid Inclusion and Oxygen Isotope Constraints on the Origin and Hydrothermal Evolution of the Haisugou Porphyry Mo Deposit in the Northern Xilamulun District, NE China

Figure 6

The Laser Raman spectra of fluid inclusions. The analyzed objects are the daughter mineral in a P-stage S-type inclusion (a), the liquid phase in a P-stage V-type inclusion (b), the vapor phase in a B-stage L-type inclusion (c), the liquid phase in a S-stage L-type inclusion (d), and the daughter mineral in a S-stage L-type inclusion (e). The results show that H₂O is the dominant component of the liquid and vapor phases of all types of fluid inclusions in different stages (a–e), with very small amounts of CH₄ (d). Daughter minerals hematite (a) and chalcopyrite (e) were also identified. P-, S-, and B-stage refer to pre-, syn-, and postmineralization stage, respectively.
