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 …
