[Truncated abstract] The Archean orogenic New Celebration gold deposit, located in the Kalgoorlie Terrane of the Eastern Goldfields Province, Western Australia, is hosted within the western segment of the first-order Boulder Lefroy fault zone (BLFZ). This setting contrasts with the majority of orogenic lode gold deposits worldwide, which are typically located in higher order splays, and as such, the New Celebration deposit provides a unique opportunity to study the hydrothermal, structural, alteration and fluid characteristics of a first-order crustal scale shear zone. Fluid inclusion, sulfur isotope and mineral chemistry were used to reconstruct the evolution of hydrothermal fluids within the BLFZ. Vein petrography, fluid inclusion microthermometry and laser ablation-inductively coupled plasma-mass spectrometry microanalysis (LA-ICP-MS) of single fluid inclusions, in addition to laser ablation sulfide sulfur isotope analyses and LA-ICP-MS mineral chemistry were combined to determine the pressure-temperaturecomposition evolution of the New Celebration gold deposit. At New Celebration, gold mineralization took place in two stages: Stage I, which is related to ductile, sinistral oblique slip fault movement and Stage II, which is related to brittle-ductile and brittle strike-slip fault movement. Type 2 quartz and quartzcalcite shear and extension veins concomitant with Stage I gold mineralization contain pseudo-secondary 2- and 3-phase aqueous-carbonic (10 ± 1 to 33 ± 13 mole % CO2) inclusions with salinities between 2 and 8 equiv. wt. percent NaCl, which were trapped between 330° and 390° C and 3.2 and 4.0 kbars. Mixed aqueous-carbonic inclusions (16 ± 3to 53 ± 28 mole % CO2) and aqueous”carbonic fluid (3 mole % CO2) inclusions with variable phase ratios and salinities of 1.9 ± 1.1to 8.7 ± 2.6 equiv. wt. percent NaCl in type 3 quartz-pyrite±sericite±calcite veins and quartz-calcite alteration associated with Stage II gold mineralization were trapped between 280° and 320° C and 0.8 to 3.2 kbars. Coexisting liquid- and vapor-rich inclusions within the same trail or cluster indicate these inclusions were trapped during phase separation. Secondary high-salinity (18.4 to 23.3 equiv. wt. % NaCl) aqueous inclusions, and metane inclusion, which postdated gold mineralization, were trapped in type 2 and type 3 veins between 100° C and 180° C and pressures below 1 kbar. Single inclusion laser ablation inductively coupled plasma mass spectrometry analyses on aqueous and aqueous-carbonic inclusions indicate that the Stage I gold related fluids were characteristically NaCa>K> Mg (K/Ca 1) whereas Stage II fluids are NaMg>K”Ca (K/Ca >1) and contained higher concentrations of, Pb, Zn, As, and W than Stage I fluids. Average Au concentrations from both Stage I and Stage II-related aqueous-carbonic inclusions returned values around 5 parts per million (ppm) although individual inclusions contained up to 51 ppm. Variations in metal ratios and elemental concentrations, in addition to K/Ca ratios potentially indicate different fluid sources for each mineralizing event and suggest that a switch occurred in fluid and/or metal sources between Stage I and Stage II...
