Fluid inclusion study of carbonate-dominated veinlets from coal seams and rocks of the Central and West Bohemian Basins, Czech Republic

Abstract

Fluid inclusions in veinlets from selected Czech Upper Paleozoic basins display large variations in salinity (0-25 wt. % eq. NaCl/CaCl2) and smaller variations in the homogenization temperatures (41-112 degrees C).

We suggest that the trapped fluids represent a mixture dominated by heated formation fluids.
