• Sedimenthosted Copper—Lead—Zinc deposits | SpringerLink

    Abstract. The recognition of sedimentary processes in the genesis of basemetal deposits can be traced back to Werner's observations on the German Kupferschiefer in the late eighteenth century. Werner's belief that all rocks and ores were of sedimentary origin led eventually to the discrediting of his views on ore genesis.
