| Abstract: | Presents results of reaction path calculations using the chemical speciation and reaction path program SOLVEQ and CHILLER to model possible fluorite deposition mechanisms in the Illinois-Kentucky fluorspar district. The results indicate that the fluids responsible for Illinois-Kentucky fluorspar mineralization were most likely quite acidic (pH < 4) and rich in fluorine in order to produce the fluorite-rich, dolomite-poor mineral assemblages and extensive dissolution of host limestones. A possible source for the acid and fluorine may have been HF-rich gases which were expelled from alkalic magmas and then incorporated by migrating basinal brines. An analysis of the geologic setting of other fluorite deposits and districts worldwide suggests that involvement of magmatic gases is probable for many of these districts as well. -from Authors |
