Calcium-rich inclusion solutions in fluorite from the Strzegom pegmatites, Lower Silesia

Andrzej Kozłowski


Inclusions in fluorites from pegmatitic druses in the Strzegom massif bear aqueous solutions with calcium chloride as the main solute component. Homogenization temperatures were measured (165 to 180°C) and the physic-chemical analysis of incIusion fluid behavior during freezing down to -130°C was performed. This yields the following fluid composition H2O – 76 wt.%, CaCl2 – 18 wt.%, NaCl – 6 wt.%. The
discussion of possible presence of other salts is presented.
