A summary follows, with a short paper available here.
The vast goldfields of the Witwatersrand are enveloped by even larger hydrothermal alteration systems to which gold mineralisation has been related. However, the timing of hydrothermal alteration and mineralisation remains controversial and the localisation of more than 90% of gold in conglomeratic packages requires explanation. We utilise detailed studies in the West Rand (South Deep and Randfontein) and observations elsewhere to address these questions and account for the scale and other key aspects of Witwatersrand auriferous systems.
Greg is presenting this talk as a tribute to Vic Wall, a significant figure in the geological sphere, who the email writer had the honour and pleasure to know.
Vic unfortunately passed away in 2017 after a long fight with illness, and we urge you to read this obituary written by colleagues.
Greg Hall is a geological consultant of Golden Phoenix International Pty Ltd. Greg was Chief Geologist for Placer Dome Group from 2000 to 2006. He managed exploration in Western Australia for CSR Limited until 1988 and Placer Dome from 1988 to 2000. The discovery of Rio Tinto’s Yandi iron ore mine and Gold Fields’s Granny Smith gold mine in WA are highlights in his career.
