The Tiemurt Pb-Zn-Cu deposit is a medium-sized Pb-Zn-Cu deposit (metal reserve: 0.29 Mt Pb + Zn and 0.14 Mt Cu) (Wang et al., 1998). The three main orebodies …
The Huangshaping W–Sn–Pb–Zn and Cu–Pb–Zn skarn mineralization systems have formed multi-types of pyrite in the calcite-sulfide and siderite-sulfide stages, which are inferred to have hydrothermal origins based on their high As/Ni ratios (9.82–36,061) and coexistence with hydrothermal minerals (calcite, siderite, sericite, …
Zn-Pb-Ag mineral deposits are the products of hydrothermal ore-forming systems, which are restricted in time and space. In Australia, these deposits formed during three main periods at ~2.95, 1.69 to 1.58, and 0.50 to 0.35 Ga.
The study focuses on the Cu-Pb-Zn tailings pond in Huili County (27°05′50″ N, 102°13′55″ E), located in the Anning River Basin of the western part of Sichuan Province, China, serving as the tailings storage facility for the Tianbaoshan Cu-Pb-Zn mine (Zhou, Gao, Chen, and Liu, 2013; Zhu, Wen, Zhang, and Fan, 2016).The deposit is rich in Cu, Pb …
