Geochemical Modelling

We are expert in applying geochemical modelling in unravelling different geological processes

Our highlights

• Calculate mineral stabilities, phase diagrams, activity diagrams
• Simulate fluid-rock reactions
• Wide temperature and pressure range: 25-1000ºC, 0-5000bar
• Comprehensive customised database: minerals, chemicals, fluids, gas, liquids, mineral solid solutions

Previous successful examples

• Simulate Au-As-Sb formation in Fosterville Gold deposits, Victoria
• Thermodynamic modelling of uranium mineral dissolution and precipitation in groundwater. The figure below shows Stability of uranium minerals and aqueous species of average Napperby groundwater composition
• HREE mineralization in Regolith-hosted deposit in Southeast China
• Fe-U-REE minerlization in IOCG deposits, e.g., Olympic Dam, South Australia
• Applying As as an exploration tool in gold deposits
• Simulate Au-Te mineralization in Golden Mile, Kalgoorlie
• Geochemical modelling of the formation of sediment-hosted Zn-Pb deposits. The figures below show that carbonate replacement is key to the deposition of sphalerite. For more details, see a Geology paper here.
