Representative laser Raman spectra of fluid inclusions. (a) Spectrum for the gas phase of type Ia inclusion in the early stage with few contents of CH₄; (b) spectrum for the gas phase of type II inclusion in the early stage; (c) spectrum for the gas phase of type Ib inclusion in the middle stage; (d) spectrum for the gas phase of type II inclusion in the middle stage; (e) spectrum for the gas phase of type IIIa inclusion in the middle stage with few contents of H₂S and CO₂; (f) spectrum for the gas phase of type IIIa inclusion in the late stage.
