摘要: The contents of polycyclic aromatic sulfur compounds (PASCs) in the Kupferschiefer varied from sample to sample. Twenty PASCs were determined Poland and Germany. Gold enrichment was only observed samples with higher PASC contents. At same time, all gold originated areas close redox boundary (the front section ofRote Faule) that formed by oxidizing brines contact reducing Kupferschiefer. It is proposed gold-bearing solutions encountered could easily displace chloride ions aurous complexes form stable S-chelates. Subsequent oxidation these organic destroy components lead formation metallic gold.
