Mineralization of Zn-Pb-Ag and associated critical metals: An
Song et al. (2023) studied the metal sources of the Zhugongtang Zn-Pb deposit in northwestern Guizhou province, South China. The results suggest that sphalerite is the main Cd-bearing mineral and Cd was most likely incorporated into sphalerite via (Fe 2+, Cd 2+) ↔ Zn 2+ substitution. The different Cd isotopes and Zn/Cd ratios support a mixing model for the metal …

Contrasting regimes of Cu, Zn and Pb transport in ore-forming
Sulfur and chlorine are the two most important ligands accounting for metal transport in the upper crust. In this study, four metal- and sulfur-saturated model fluids with varying salinities and redox states were simulated in the Fe-Cu-Pb-Zn-Au-S-C-H-O system, over a wide pressure-temperature (P-T) range (50–650 °C, 0.8–5.0 kbar), in order to compare the …
