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