10% Pb + Zn, and Zn dominated. A viable mine requires an overall grade 8%, with ore beds 15%Zn, and thicknesses 3m. ENVIRONMENT: Ordovician platformal carbonate rocks (Appalachian Zinc,e.g., Daniel’s Harbour), and Carboniferous basinal carbonate rocks (SW Mississippi Pb-Zn).

All about skarns

Nov 02, 2007 Au, Cu, Fe, Mo, Sn, W, and Zn-Pb skarn deposits. Groupings of skarn deposits can be based on descriptive features such as protolith composition, rock type, and dominant economic metal(s) as well as genetic features such as mechanism of fluid movement, temperature of formation, and extent of magmatic involvement.

Fluid source and metal precipitation mechanism of sediment

Mar 01, 2021 Py II-1 and py II-2 in stage II contain elevated As, Pb, Cu, Sb, Zn, and Ag with low mean Au content (3.3 ppm) and have δ 34 S ranges of −2.8 to +1.2‰ and −6.2 and −0.8‰, respectively. Galena in stage II has lower radiogenic Pb isotope ratios than stage I pyrites, indicative of a different Pb source or fluid evolution.

2.4 Iron oxide copper gold mineral system Geoscience

Iron oxide copper-gold (IOCG) deposits (Hitzman et al., 1992) are a diverse family of mineral deposits characterised by the following features: (1) Cu with or without Au, as economic metals, (2) hydrothermal ore styles and strong structural controls, (3) abundant magnetite and/or hematite, (4) Fe oxides with Fe/Ti greater than those in most igneous rocks, and (5) no clear spatial associations ...

Polymetallic replacement deposit Wikipedia

A polymetallic replacement deposit, also known as carbonate replacement deposit or high-temperature carbonate-hosted Ag-Pb-Zn deposit, is an orebody of metallic minerals formed by the replacement of sedimentary, usually carbonate rock, by metal-bearing solutions in the vicinity of igneous intrusions. When the ore forms a blanketlike body along the bedding plane of the rock, it is commonly ...

It was Canada's longest lived continuous mining operation and produced metals worth over $20 billion in terms of 2005 metal prices. Grading was in excess of 5% Pb and 6% Zn. The ore genesis of the Sullivan ore body is summarized by the following process: Sediments were deposited in an extensional second-order sedimentary basin during extension.
