 — Cu and Zn were also strongly correlated (r = 0.82), and they had a weaker correlation with Pb (Pb-Cu, r = 0.5; Pb-Zn, r = 0.35). This seems to indicate that Fe and Mn are elements that can share similar sources; in fact, they have been reported as elements of natural or mixed origin ( Dehghani et al., 2016 ), in studies of heavy metals.

 — Mill tailings from skarn-type base metal deposits were studied in order to ascertain potential element mobility in response to weathering. Hypogene ore minerals are sphalerite, galena, and chalcopyrite, showing minor supergene oxidation to smithsonite, cerussite, and covellite. Gangue minerals are pyrite, pyrrhotite, magnetite, hematite, …

 — La Colorada, in Zacatecas State, Mexico is an epithermal Ag-Zn-Pb system hosted in Mesozoic calcareous sedimentary rocks overlain by Tertiary volcanic rocks. The dominant vein is associated with a fault system that accommodates Tertiary normal and strike-slip faulting.

About Pb-Cu. Lead and zinc are extremely close in nature, especially in primary deposits, and often coexist. Most of the lead-zinc minerals are sulfides and sulfates, and galena and sphalerite are the primary Pb-Zn ores. Non-sulfide: It is formed due to hypogene and supergene weathering. Mostly oxide ores like zincite, and cerussite may fall under this …
