Identification of Two Types of Metallogenic Fluids in the Ultra-Large Huize Pb–Zn Deposit, SW China

Figure 5

Typical photographs of the mineral-forming sequence of the Huize Pb–Zn deposit. (a, b) Coarse-grained Py stage (Stage I); (a) (+)10 × 2; (b) (−)10 × 2. (c) Sp–Gn stage (Stage II): edge-shared texture between Sp and Gn; the sphalerite content is far greater than galena. (d) Gn–Sp stage (Stage III): harbor structure of Gn replacing Sp; Gn is the main mineral. (e, f) Fine-grained Py–Dol–Cal stage (Stage IV); (e) (+)10 × 2; (f) (−)10 × 4. Sp: sphalerite; Gn: galena; Py: pyrite; Dol: dolomite; Cal: calcite.
