The geology of the Tennant Creek gold and copper field Progress report on the work of the 1958 field season

The aim of the 1958 work at Tennant Creek was to supplement previous surveys by re-mapping part of the field in greater detail than had previously been possible. The rock types mapped during this programme comprised sediments of the Warramunga Group, quartz-felspar porphyries, quartz-magnetite and quartz-hematite lodes, jasper lenses, quartz reefs, lamprophyre dykes, the Rising Sun Conglomerate and Recent superficial deposits. The origin of the gold and sulphide orebodies of this field are discussed in the light of the latest available data, and an attempt is made to assess the significance of recent geochemical and geophysical work in the area.
