A- Isotopic composition of aqueous fluids extracted from the fluid inclusions quartz veins from the MBM. Two methods (thermal decrepitation and crushing) have been used to extract the fluids from horizontal, vertical and syntectonic veins and two methods (conventional and the new method developed in this study) have been uses to analyse the fluid inclusions. B - Isotopic composition of aqueous fluids extracted from the fluid inclusions quartz veins from the CM. Two methods (thermal decrepitation and crushing) have been used to extract the fluids from the vertical veins and two methods (conventional and the new method developed in this study) have been uses to analyse the fluid inclusions.
