Application of 3-D seismics to mine planning at Vaal Reefs gold mine, number 10 shaft, Republic of South Africa ... The seismic survey at No. 10 shaft accurately and spectacularly delineated the 3-D structure of the Ventersdorp contact reef at depths ranging from 1000 to 3500 m, imaging faults with throws in the 20- to 1200-m range. ...

To constrain the origin of the gold, we analyzed Vaal Reef (VR) gold samples associated with carbonaceous material and mostly authigenic in appearance. We also analyzed pyrite grains interpreted to be of detrital, diagenetic, and authigenic origin (1,2) from the VR, Steyn Reef (SR), and Ventersdorp Contact Reef (VCR) (fig. S1, Table 1).

Gold is found within a less-than-2m-thick laterally large quartz pebble conglomerate horizons or reefs. The Vaal Reef is a laterally extensive, rich conglomerate that dominates the mine. The Vaal reef includes successive quartzite packages and oligomictic conglomerates concentrated on a series of non-conformities.
