Volcanogenic massive sulfide (VMS) deposits are one of the most important sources of metals (mainly Cu, Zn, Pb ± Au) in the world (Mercier-Langevin et al., 2011, Hannington, 2014, de Ronde et al., 2019).Metallogenesis of this kind of deposit is often complex and multistage, making it difficult for ore geologists to obtain detailed ore-forming information.

Gold-bearing skarns may contain significant amounts of numerous other commodities, including copper, lead, zinc, and iron and (or) they may have been mined in the past for these or other …

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 …

The Howard's Pass district of sedimentary exhalative (SEDEX) Zn-Pb deposits is located in Yukon Territory and comprises 14 Zn-Pb deposits that contain an estimated 400.7 Mt of sulfide mineralization grading 4.5 % Zn and 1.5 % Pb. Mineralization is hosted in carbonaceous and calcareous and, to a lesser extent, siliceous mudstones.

The Yinshan Cu–Au–Pb–Zn–Ag deposit is located in the famous Dexing copper–gold polymetallic district in South China (Fig. 1). This polymetallic district consists of the Middle Jurassic (ca. 170 Ma) Yinshan Cu–Au–Pb–Zn–Ag deposit (950,000 tons of Cu and 107 tons of Au) (JGEB, 1996, Yinshan Lead-Zinc Mine, 1993, Wang et al., 2011b), the Middle …

The Bieluwutu Cu-Pb-Zn deposit is located in the Ondor Sum region of the western Xing'an-Mongolia orogenic belt, North China. The host rocks of the deposit consist of metasandstone, tuffaceous slate, andesitic tuff and fragmented felsic volcanic rocks, which have previously been regarded as the Early Carboniferous Amushan Group.

Therefore, the Tiemurt Pb-Zn-Cu deposit is likely an example of orogenic Pb-Zn + Cu systems formed in collision orogeny, rather than a pre-collision VMS or Sedex system developed in Devonian; and ...

From analysis of 52,760 assays from across the deposit it was found that there was a very poor correlation between gold and each of Fe, Zn, S, Pb, Cu, As and Ag, whereas Ag correlated reasonably well with both Pb and Zn. Results from EPMA shows that gold varies widely in composition from host-rock associated gold (96 wt.% Au) through more ...

Orogenic gold deposits are the main source of gold reserves in the world and their geochemical characteristics and tectonic settings are known to geologists (Groves et al., 1998).The possibility and potential of orogenic-type Ag, Pb–Zn, Cu, Mo and other metals are proposed, considering their geochemical similarities (Chen et al., 2004b, Chen, 2006, Pirajno, …

The Freiberg Ag-Pb-Zn district has recently been identified as a prime example of a vein-style epithermal ore deposit (Burisch et al., 2019b, Swinkels et al., 2021). It was primarily mined for Ag (1168–1900) as well as for Pb, Zn, Cu, and Sn during the last stages of active mining (∼1935–1969; Baumann et al. 2000). The district is located ...
