Characteristics of structurally superimposed geochemical …

There are five main types of ore in the polymetallic Xiasai silver-lead-zinc deposit, i.e., Ag-rich Pb ore, Ag-Pb-Zn ore, Ag polymetallic ore, Ag-Pb ore and brecciated oxide ore. The major ore minerals include metallic sulfides, Ag-bearing sulfide minerals (Cu-Sb-Ag and Sb-Ag) and Bi- and Sb-bearing lead sulfides (Pb-Sb and Pb-Bi).

Lead and Zinc Mining in the Dubuque Area

The metallic lead and zinc in MVT ore deposits are chemically bonded with sulfur to form sulfide minerals. The ore deposits were formed as sulfide mineral crystals precipitated from the hot brines on the walls of open, vertical fractures (cracks) in carbonate rocks below the surface. As crystal growth continued, all open space was filled,
