Gold-Transporting Hydrothermal Fluids in the Earth's Crust (Geological Society Special Publications)

Hydrothermal Ore Deposits That Are Exploited For Gold Include Both Gold-only Deposits, Such As Orogenic Deposits, And Gold-bearing Examples Of The Common Hydrothermal Deposits Types That Are Formed Around Upper-crustal Magmatic Centres, In Particular Porphyry And Epithermal Deposits. Fluid-inclusion Data Have Shown That Ore Fluids Of Gold-only Deposits Are Compositionally Distinct Compared To Fluids Of Other Deposit Types. This Special Publication Includes An Up-to-date Summary Of Thermodynamic Parameters Of Aqueous Au Species At High Temperatures And Pressures; A Dataset Of Fluid Inclusion Properties And Compositions From Orogenic Deposits Of Different Parts Of The World; Several Comprehensive Case Studies Of Different Types Of Gold Deposits And Their Fluids From Usa, Brazil, Egypt, Slovakia And Bulgaria; And Numerical Modelling Aimed To Define Key Parameters That Affect Fluid Flow And Gold Deposition At A Range Of Scales.
