CHAPTER 5
GENERAL DISCUSSION
5.1. Introduction
Results presented in the preceding chapters contribute in understanding the
Proterozoic tectonic evolution and U mineralizing system in successor basins in the
Beaverlodge area of Northern Saskatchewan, Canada, and the South Alligator River area of
the Northern Territories, Australia. Based on structural, geochemical, geochronological and
petrographic relationships, this research has evaluated the character and formation of U
deposits in successor basins by detailing the relative timing relationships between
deformation and fluid events, elucidating the timing, nature and origin of ore-forming
fluids, identifying critical key structural and geochemical factors controlling U
mineralization, and presenting a conceptual genetic model for U mineralization in successor
basin areas (Fig. 5.1.).
The following elucidates the general models for uranium mineralizing systems in
Paleoproterozoic successor basins, compares them with the unconformity-related uranium
mineralization in the younger, U-rich Athabasca and Kombolgie basins and discusses the
potential implication for uranium metallogeny and exploration strategy in others
Paleoproterozoic successor basins in Finland and Guyana.
