| Abstract: | Whole-rock ??18O and ??D values from the Garden Creek Phyllite define an isotopically depleted zone (60 km2) around the Nevada Mountain stock and are the result of high-temperature interactions with ancient meteoric waters at water/rock ratios ranging from 0.002 to 0.09. Comparison of the ore fluid ??18OH2O and ??DH2O values with hypothetical waters equilibrated with the Garden Creek Phyllite indicates that the hydrothermal fluids must have also interacted with the basal dolomite of Bayhorse Creek, which underlies the phyllite. The ?? 13CCO2 values for the hydrothermal fluids also record a transition from early water/rock interactions that were dominated by the Garden Creek Phyllite to later interactions that were influenced significantly by the basal dolomite of Bayhorse Creek. The range of ??34S values may be interpreted as either a heterogeneous sedimentary source or mixed sedimentary-magmatic sources. -from Authors |
