Web11 apr. 2024 · Hydrothermal titanite is a common accessory mineral in the stratabound Pb-Zn deposit in the central Fujian area, which is highly resistant to weathering and post-mineralization alteration (Mezger et al., 1991, Scott and St-Onge, 1995, Xing et al., 2024).Furthermore, the closure temperature for Pb diffusion in titanite is >600°C, which …
WebMoreover, because H 2 S is the predominant source of S in hydrothermal systems, precipitated sulfides often exhibit similar δ 34 S values [80,81]. Considering that no sulfate minerals were found in these ores, the δ 34 S values of the Au-bearing sulfides likely represent the S isotope characteristics of auriferous fluids.
