Abstract/Notes | Stratiform quartz-sulphide-gold veins, locally termed "reefs", are hosted within the Proterozoic Transvaal Supergroup sediments in the Sabie-Pilgrim's Rest Goldfield, eastern Transvaal. These deposits have produced about 180 tonnes of gold and share many characteristics with those of Telfer, Western Australia. Detailed examination of the Elandshoogte Gold Mine shows that gold deposition occurred in two stages, both linked to
bedding-parallel thrusting within the sedimentary pile. The majority of gold was introduced in the second stage of mineralisation. New data on post-reef thrust deformation is presented. Thrust-related fractures in early sulphides are a preferred site of late gold and the role of structure in preparing sites for mineralisation and transporting fluids is emphasised. Fluids accompanying faulting are implied to have transported gold and a magmatic source of mineralisation is suggested. |
