• Skarn Deposits

    Distal Pb-Zn skarn deposits commonly contain the bulk of ore in carbonate gangue beyond the skarn zone and may be linked with certain manto and vein deposits of Pb-Zn-Ag An important factor in the formation of Zn-Pb skarn deposits is the travel distance of hydrothermal fluids between source and reactive limestone, which results in depletion of fluids in Mg, Al, and Cu and relative enrichment.
