The Fe/Mn ratio of fluid inclusions from low-grade metamorphic quartz veins has been analyzed by an improved crush-leach method. When compared with Fe and Mn in coexisting vein chlorites, exchange between fluid and chlorite is shown to vary with the redox state of the wall rocks, but is independent of the salinity of the fluid. Agreement between our results and theoretical predictions of Fe/Mn partitioning between fluid and chlorite are good for veins from relatively oxidized rocks, but vein fluids from reduced hosts are enriched in Fe.
