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 5

Photomicrographs of representative samples from the Keyue Sb–Pb–Zn–Ag deposit. (a) Assemblage 1 automorphic arsenopyrite. (b) Later formed assemblage 2 galena cut and replaced early formed sphalerite–pyrite–Mn–Fe carbonate. (c) Assemblage 4 tetrahedrite replaced assemblage 3 pyrite–sphalerite–galena–quartz. (d) Assemblage 4 boulangerite replaced assemblage 3 sphalerite–quartz. (e) Assemblage 5 quartz–stibnite vein cut the assemblage 4 boulangerite. (f) Assemblage 5 stibnite occurred among xenomorphic quartz grains. Abbreviations are the same as in Figure 4.
