Previous coring of similar reef sediments with a 76-mm-diameter vibrocore reached depths of 4 m (John Brewer Reef; Walbran et al. 1989 ), and 75-mm-diameters cores driven by hydraulic jackhammers reached depths...

... ( Cooper, 1923 ). Interest in nuclear warfare included a search for uranium resources, and widespread radioactivity was mapped in several Witwatersrand reefs around 1945. The origin of the radioactive minerals, uraninite and brannerite mostly, was quickly linked genetically to the gold in these reefs...

The buildups are notable because of their large size (several to tens of kilometers wide and up to 250 m...
