Summary:Microthermometric measurements on fluid inclusions reveal different inclusion types which can be used to model the evolutionary trend of the hydrothermal fluids in the Galway granite. Due to immiscibility an originally homogeneous H2O- CO2-bearing fluid became unmixed and created a CO2- dominated and a H2O-dominated species. The aqueous one followed a dilution path and caused the Mo-Cu-mineralization at Mace Head and Murvey. Finally a high saline (CaCl2)-low T fluid interacted with the rocks. [R.E.S.]
