A mineralogical and geochemical study of alteration associated with the Ventersdorp Contact Reef in the Witwatersrand Basin, South Africa.

[摘要] The Ventersdorp Contact Reef(VCR) is a major gold-bearing reef in the Witwatersrand Basin.It occurs between the overlying Klipriviersberg Group lavas and the underlying Central RandGroup sediments, and was strongly altered by hydrothermal fluids circulating in the WitwatersrandBasin. A detailed study of the mineralogy, geochemistry of rocks and minerals, physicochemicalconditions, stable isotopes and ages of hydrothermal alteration zones associated with the VCRwere carried out at Western Deep Levels South Mine, South Africa.
