英文摘要	Primary fluid inclusions in quartz and carbonates from the Kanggur gold deposit are dominated by aqueous inclusions, with subsidiary CO2-H2O inclusions that have a constant range in CO2 content (10-20 vol %). Microthermometric results indicate that total homogenization temperatures have a wide but similar range for both aqueous inclusions (120degrees to 310degreesC) and CO2-H2O inclusions (140degrees to 340degreesC). Estimates of fluid salinity for CO2-H2O inclusions are quite restricted (5.9-10.3 equiv. wt% NaCl), whereas aqueous inclusions show much wider salinity ranging from 2.2 to 15.6 equivalent wt % NaCl.;The deltaD values of fluid inclusions in carbonates vary from -45 to -61 parts per thousand, in well accord with the published deltaD values of fluid inclusions in quartz (-46 to -66 parts per thousand). Most of the delta(18)O and deltaD values of the ore-forming fluids can be achieved by exchanged meteoric water after isotopic equilibration with wall rock by fluid/rock interaction at a low water/rock ratio. However, the exchanged meteoric water alone cannot explain the full range of delta(18)Oand deltaD values, magmatic and/or metamorphic water should also be involved. The wide salinity in aqueous inclusions may also result from mixing of meteoric water and magmatic and/or metamorphic water.
