dc.description.abstractThe paragenesis of the Kanmantoo Cu-Au Deposit, South Australia, has been a topic of debate in the literature since research on the site was first published. Due to the deposit’s complicated geological history of metamorphism and deformation, determining the source of ore-forming fluid has been difficult. Two major models have been hypothesised; a post-peak metamorphic model suggesting granitic fluid to be the source of mineralising fluids; and a syn-sedimentary model, hypothesising that the mineralisation occurred in a Sed-ex style while the Kanmantoo Group was still being deposited. This study employs a range of techniques such as, stable oxygen and hydrogen isotopes; Cu, Zn, and Pb trace elements within silicate gangue minerals; xenotime, zircon and monazite geochronology; and mineral equilibria forward modelling in an attempt to constrain the conditions of the ore-forming fluid. From these data, the age of mineralisation has been constrained to 489Ma through the use of xenotime geochronology. Mineral equilibria forward modelling has indicated peak-mineralisation conditions of ~3.5 GPa and 570 °C.
