Lead and Zinc. Lead and zinc ores are found so often mixed that they are described together. In addition to galena and zinc blende, pyrite is generally present and often in considerable quantities, and copper pyrites is generally present. By weathering, the latter may leave green and blue stains. The ore deposits are of two principal kinds:

Lead beads, dating to more than 6,000 years ago, have been found in Turkey, suggesting that galena was known at that time since naturally-occurring metallic lead is rare. To produce lead, galena is ground up and roasted, producing lead oxide, which is heated with carbon in a blast furnace, to make metallic lead.

From early on, researchers observed that the Pb isotope compositions of lead ore deposits, in the form of galena, appear to follow a simple isotopic growth curve (Cooper et al., 1969; Russell and Allan, 1955). Fig. 5 shows the growth distribution of the Pb isotope composition of Australian galena (Huston et al., 2019) (Supplementary Data Table ...
Other sulphide minerals such as sphalerite (zinc sulphide) and galena (lead sulphide) are broken down in the oxidized zone. Galena will form cerrusite, anglesite and wulfenite. Sphalerite forms smithsonite. Oxidized zones are found in many deposits, frequently found in arid areas of the world including the United States, Mexico, Peru, …

Galena is the natural mineral form of lead sulfide (PbS). The mineral occurs as fine to large crystals due to syntectonic remobilization at low temperature and move to a suitable location. The color is shining lead-gray and silvery (Fig. 1.39) with high specific gravity between 7.2 and 7.6 g/cm 3 containing 86.6% Pb in the purest form.
Consequently, this paper examines all available galena lead isotope data related to this area.
