timing relationships between fault activities, hydrothermal and ore-forming processes
to regional thermotectonic events.
f) Uranium deposits in the Beaverlodge and South Alligator River area are older than
those in the U-rich Athabasca and Kombolgie basins. Rocks that host these deposits
have been folded and exhumed during subsequent tectonic events. These older U
deposits can be considered as a potential source for detrital uraninite that fed sediments
of the Athabasca and Kombolgie basins and therefore contributed to the inventory of
uranium that formed unconformity-related U mineralization in the younger basins.
g) Uranium deposits in the Beaverlodge and South Alligator River areas share many
similarities with those associated with the Jatulian successor basin of the
Fennoscandinavian shield of central Finland. The overlying late Mesoproterozoic
Satakunta Basin can be considered as being a potential basin to host unconformityrelated
U mineralization similar to those in the Athabasca and the Kombolgie basins.
Similarly, the Roraima basin in Guyana has also potential to host unconformity-related
U mineralization.
h) The occurrence of older U mineralization associated with successor basins and
basement lithology can be considered as a new criterion for exploration of
unconformity-related uranium mineralization in younger Paleoproterozoic basins.
