Summary:Molybdenite-bearing greisens from the Austrian part of the Moldanubian zone occur together with peraluminous leucogranites. The calculated mass balance range is similar to the observed porosity of the greisens. Main mineralizations are pyrite, chalcopyrite and molybdenite. During progressive alteration a decrease in Th combined with an increase in Na-Cl content in the fluid inclusions is correlated with a decrease of Na2O concentrations in the bulk rocks, which is interpreted as an exchange of metal ions against Na in a Cl-rich solution.
