Abstract

The fluids trapped in inclusions in pegmatitic minerals and surrounding rocks from this area document the evolution of the system from a high-T (> 500 degrees C assuming a P of 1.5 kbar), water-rich fluid, containing small amounts of CO (sub 2) , CH (sub 4) , H (sub 2) S and N (sub 2) , through an intermediate (approx 400 degrees C) fluid, down to a low-T (approx 300 degrees C) fluid. Salinities remained constantly low (max. approx 7 eq.wt.% NaCl); Na, K and Cl appear as major components of the dissolved salts. The lowest salinity values are typical of the lowest T fluids, and may indicate the input of a largely meteoric component, as opposed to fluids of the earliest stage, for which a dominantly magmatic nature is suggested. Whether this early magmatic fluid coexisted with a silicate-rich melt remains an open question, although the presence of early crystal-rich inclusions may support such a coexistence.
