Geology, Mineralogy, Fluid Inclusion, and H–O–S–Pb Isotope Constraints on Ore Genesis of the Keyue Sb–Pb–Zn–Ag Deposit in Southern Tibet

Figure 8

Photomicrographs showing the types and characteristic features of fluid inclusions (FIs) at the Keyue Sb–Pb–Zn–Ag deposit. (a) Coexistence of the primary and secondary FIs that linearly distribute in assemblage 3 quartz. (b) The pseudosecondary FIs linearly distribute in assemblage 4 quartz. (c) The elliptic V-type FIs in assemblage 3 quartz. (d) The long-columnar C-type FIs in assemblage 3 quartz. (e) The irregular halite-bearing FIs in assemblage 4 quartz. (f) The elliptic G-type FIs in assemblage 3 quartz. (g) The rectangular L-type FIs in assemblage 1 Mn–Fe carbonate. (h) The rhombic L-type FIs in assemblage 2 Mn–Fe carbonate. (i) The L-type FIs isolatedly distribute in assemblage 5 quartz. (j) The long-columnar L-type FIs in assemblage 2 sphalerite. (k) The long-columnar L-type FI inclusions in assemblage 2 sphalerite. (l) The S-type FIs in assemblage 2 sphalerite. Abbreviations are the same as in Figure 5.
