Genetical Significance of Saline Relics in Carbonate Host Rocks of Alpine Pb-Zn Deposits

摘要: Geochemical research on saline relics in Alpine Pb-Zn deposits established important indications as to the composition and concentration of ore-bearing solutions. The investigations proceed from principle that solutions are commonly responsible for formation ore deposits. Therefore mere existence had be proved initially. For this purpose a leaching method was developed applied barren mineralized rocks Bleiberg-Kreuth (Austria) Raibl (Italy) Predominantly Ca2+, Mg2+, SO 4 2- , accompanied by generally minor amounts Na+, K+, Cl- were found leachates. Only Cl-, Mg2+ (Ca2+) can assigned fluid inclusions salt crystals, here referred ”saline relics”.
