The gold--uranium ores of the Witwatersrand goldfields consist mainly of compact
metumorphosed conglomerates occurring as bands in a thick body of sediments spread�…

Field observations and experimental results show that gold is mobile under a wide range of
natural conditions in the surficial environment. However, the extent to which, and the form (s)�…

This workshop was held to examine the origins of uranium bearing placer deposits of South
Africa, Canada and the United States in order that future prospectors who are seeking new�…

Some types of uranium deposits have been described and partially classified by people who
have worked only with restricted types of deposits. Thus, in some cases, misleading and�…

The ubiquitous association of pitchblende uranium deposits with terrestrial sediments is
believed to be the natural result of formation of the orebodies by surficial processes�…

[en] The ancient pyritic ore conglomerates have a common origin best exemplified by the
Witwatersrand deposits. All contain detrital pyrite and uraninite, which are unstable in�…

Some genetic models for Lower Proterozoic gold-and uranium-bearing pyritic
conglomerates favour a modified placer origin in which low levels of atmospheric oxygen�…
