The Fluids in Quartz from Central Bosnia

The fluids in vein-quartz from the Midd-Bosnian Schist Mts. were investigated by cryometric and thermometric measurement. There are two groups of fluid inclusions (FIs): aqueous and aqueous-carbonic FIs. Aqueous FIs were determined in all observed samples, and aqueous-carbonic FIs were observed only in the samples from Čemernica and Međuvršje. Aqueous FIs from Čemernica are KCl-NaCl-H2O FIs. Aqueous-carbonic FIs from Čemernica contain, except CO2, other volatiles (CH4, N2). In the FIs from the area of Međuvršje and Raštelica could be developed 4 or 5 types of hydrates. This type of FIs was determined as CaCl2 FIs with presence of other cations. Aqueous-carbonic FIs from Čemernica contain high concentration of other volatiles. Salinity of aqueous FIs is higher then salinity of aqueous-carbonic FIs. Salinity in the both types of FIs is higher in fluids from Međuvršje and Raštelica then into FIs from Čemernica. Temperatures of homogenization of all types of FIs are similar and were around 300°C.
