Sulphur isotope variation at Broken Hill and Black Mountain, Aggeneys
Description
The Broken Hill and Black Mountain sediment-hosted, stratiform Pb-Zn-Cu-Ag deposits at Aggeneys are found, 6 km apart in the mid-Proterozoic Bushmanland Sub-province of the Namaqua Belt. Magnetite-rich rocks and ferruginous/garnet quartzites are well represented at both deposits, with significant massive sulphides at Broken Hill and barite at Black Mountain. Von Gehlen reported 9 sulphide sulphur isotope results from Black Mountain, 19 from Broken Hill and 24 from the Gamsberg Zn deposit some 20 kilometers to the east. In the present study a further 55 determinations have been made, 15 from Black Mountain and 40 from Broken Hill, to give a wider geographic spread over the deposits and more representative sampling of various rock types within them. 2 figs., 3 refs
