The application of P-T-X(CO2) modelling in constraining metamorphism and hydrothermal alteration at the Damang gold deposit, Ghana

Abstract:

Orogenic gold mineralization at the Damang deposit, Ghana, is associated with hydrothermal alteration haloes around gold-bearing quartz veins, produced by the infiltration of a H2O-CO2-K2O-H2S fluid following regional metamorphism. Alteration assemblages are controlled by the protoliths with sedimentary rocks developing a typical assemblage of muscovite, ankerite and pyrite, while intrusive dolerite bodies contain biotite, ankerite and pyrrhotite, accompanied by the destruction of hornblende....
