Abstract

Progressive decarbonation of marble accompanying the wollastonite-forming reaction gave rise to an aqueous fluid in the NaCl-(KCl)-CaCl (sub 2) -H (sub 2) O system saturated with respect to wollastonite. It continued to precipitate this phase, followed by calcite, probably as a result of changes in the bulk composition; this phase was a CaCl (sub 2) -rich high-salinity brine. A compositional continuum is envisaged between the two fluids, but in both cases the CO (sub 2) content was very low (X approximately 0.05). The inferred high CaCl (sub 2) (and SiO (sub 2(total)) ) contents of the fluid can be explained by the existence of HCl in the primary fluid introduced from the nearby granite.
