A major constraint on the formation of epigenetic hydrothermal lead-zinc deposits is the low solubility of lead and zinc sulphide in aqueous solutions (Fig. 2). Thus, only small quantities of lead and zinc can be transported in a reduced sulphide solution, and unrealistically large volumes of such a fluid are required to form economic lead-zinc ...A CONTRIBUTION TO ECONOMIC GEOLOGY w_ - ~ _____.^ GEOLOGICAL SURVEY BULLETIN 1027-K Prepared in cooperation with the Iowa Geological Survey ... zinc-lead district began about 1788, although small amounts of lead lio-d. l>eeix

1926 the value of lead-bearing ores constituted over 98 per cent of the yield from all lode and placer mines. Zinc. Most of the lead-bearing ore contains some zinc, and there are a few lodes in which zinc is the dominant valuable metal. The amount of zinc produced depends on the demand arid on metallurgi­ cal progress.Sediment-hosted Pb-Zn deposits contain the world' s greatest lead and zinc resources and dominate world. ...

Lead has been a much-sought-after commodity in North America since early Colonial times. Although more sophisticated uses, such as in pipes and vessels in water systems, coins, pottery glaze, and roofing, were common in Babylonian, Egyptian, and Roman cultures, the principal need for lead on the American frontier was to make bullets.Zinc. Zinc is a bluish-white, lustrous metal with the chemical symbol Zn. Its main ore mineral is sphalerite (ZnS). Some of its uses are for galvanizing (plating thin layers of zinc onto iron or steel to protect from corrosion), production of brass (combination of zinc and copper), and coloring in rubber and paint. Year of first production in ...

The geology of the Zawar lead-zinc mine, Rajasthan, India. A. Mookherjee. Published 1 June 1964. Geology. Economic Geology. The lead-zinc ores occur in a shear zone in Precambrian metasediments. The shear zone is later than the two recognized generations of folds, and contemporaneous with wall-rock alteration and subsequent mineralization.Total zinc production in the state up to 1933 was 1,488,474 pounds, almost all of which had come from the Bonanza and Alice Ray Mines in the Quitman Mountains of Hudspeth County. Texas produced 410,000 pounds of lead in 1940, but only 362,000 pounds two years later. The total production of lead in the state from 1885 to 1944 was 4,788 short tons.

Sullivan, British Columbia, Canada. Discovered over 100 years ago, the Sullivan deposit was the largest SEDEX deposit in Canada, producing 116 million tonnes of zinc (5.8 % Zn) and lead (6.7 % Pb). The mine is no longer producing but Santa Fe Metals and Eagle Plains Resources are pursuing SEDEX prospects in the area.Commonly MVT deposits form by the combination of hydrocarbon pyrolysis liberating zinc-lead ions and sulfur to form an acidic solution which dissolves the host carbonate formation and replaces it with massive sulfide accumulations. This may also take the morphology of fault-hosted stockworks, massive tabular replacements and so forth.
