文摘

Wallaby Gold Deposit has a well-established paragenesis, 5 generations all containing pyrite. Each progressive pyrite generation shows a progressive and gradual change in redox conditions. Redox trends at Wallaby are clearly related to trace elements within the pyrite. LA-ICPMS and SHRIMP-II results support the progressive changes to be redox controlled. Wallaby Gold Deposit did not result by the mixing of two separate fluids as previously advocated.
