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 …

The Mount Isa deposit is the largest known accumulation of Cu in the Mount Isa region. Adjacent to high grade Cu mineralisation sit multiple high-grade stratabound Zn-Pb-Ag orebodies. The relationship between the Cu and Zn-Pb-Ag mineralisation has been the subject of intense debate. Over the years three separate metallogenic models have …

This indicates that the ore-forming metals (esp. Cu, Pb and Zn) ... Gold, Ag, and Zn contents increase vertically from the stringer to the bedded ore facies; Cu and Co increase in the massive ore facies, and Pb is highest in the stringer zone. Ore mineralization in the Northern Chah-Farsakh deposit has emplaced in two stages.

Historical and active mining has adversely affected the geochemistry of the Jiehe River in the Jiaodong Peninsula, which has the largest gold ore reserves in China. Water and sediment samples were collected along the 37.8 km long river during the critical low flow season. Samples were analyzed for their geochemical properties, total …

The Devonian sequences in the Chinese Altay are highly fertile of base metal deposits, notably the giant Ashele Cu-Zn, Keketale Pb-Zn and Mengku Fe deposits (Wang et al., 1998; Wan et al., 2010a, Wan et al., 2010b), and the Abagong polymetallic belt (Zhang et al., 2012; Zheng et al., 2012).These Devonian sequences comprise mainly …

The Pb isotopic composition of the sulfides from the Qiandongshan–Dongtangzi Pb-Zn deposit (with 206 Pb/ 204 Pb ratios of 18.06 to 18.14, the 207 Pb/ 204 Pb ratios of 15.61 to 15.71, and 208 Pb/ 204 Pb ratios of 38.15 to 38.50) is similar to that of the Late Triassic Xiba granite pluton, suggesting that they share the …

The Coringa gold-silver (Cu-Pb-Zn) deposit, in southeastern of Tapajós Mineral Province, is hosted in felsic volcanic rocks the Vila Riozinho Formation (1996 ± 21 Ma) and in the Serra Alkali Feldspar Granite (1999 ± 25 Ma), and has been interpreted to have formed in a post-collisional volcano-plutonic setting.

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) …
