ORGANIC MATTER GENETICALLY RELATED TO THE SULFIDE ORES OF ZINC AND LEAD IN UPPER SILESIA (SOUTHERN POLAND)

Summary
Organic matter contained in large amounts in the Upper Silesian Zn-Pb ore deposits has been identified as dopplerite, calcium humate. This humic, amorphous substance precipitated from humic acids loaded by calcium ions. The precipitation of dopplerite is contemporaneous with sulfide deposition at the time of initial and mature karst processes. The hydrothermal karst dissolution supplied calcium ions but the source of humic acids is still conjectural.
