Sediment-Hosted Lead-Zinc Deposits in Earth History
Abstract. Sediment-hosted Pb-Zn deposits can be divided into two major subtypes. The first subtype is clastic-dominated lead-zinc (CD Pb-Zn) ores, which are hosted in shale, sandstone, siltstone, or mixed clastic rocks, or occur as carbonate replacement, within a CD sedimentary rock sequence. This subtype includes deposits …

Lead Deposits
Lead and zinc are often found together in ore deposits; however, less so with copper and iron. Lead compounds are formed when the metals are precipitated from the ore fluids by various processes depending on specific local conditions; the most common processes are cooling, mixing with other fluids, and pH change.
