Laser Raman spectroscopy of different fluid inclusions (FIs). (a) CO₂ spectra of vapour in C-type FIs in the early stage quartz; (b) CO₂ spectra of vapour in a few W-type FIs in the main stage rhodochrosite; (c) CO₂ spectra of vapour in C-type FIs in the main stage fluorite; (d) CO₂ spectra of vapour in C-type FIs in the main stage sphalerite; (e) transparent daughter minerals in S-type FIs of fluorite being calcite and dolomite; (f) primary S-type FIs containing dolomite daughter mineral in sphalerite; (g) the opaque daughter mineral in the early stage quartz being marcasite; (h) the opaque daughter mineral in S-type FIs of the main stage sphalerite being chalcopyrite. Qz, quartz; Rds, rhodochrosite; Sp, sphalerite; Fl, fluorite; Cal, calcite; Dol, dolomite; Ccp, chalcopyrite; Mrc, marcasite.
