文摘

The Chadormalu deposit is associated with extensive alkali earth (Ca/Mg) and alkali (Na/K) alterations. Sulfur isotope data on late pyrite suggest involvement of basinal brine in the ore system. Variable iron remobilization-reprecipitation occurred in the course of ore formation. Fluid inclusions on various apatite types, sulfur isotopes and geochemical data suggest variable degrees of fluid mixing.
