Geochemical, mineralogical and petrographic studies of the newly drilled natural fission reactor at Bangombe -Gabon

Objective



The subject of this study is the natural fission reactor of Bangombi (Gabon) representing a very high grade uranium ore where fission reactions occurred 2.0 billion years ago. As the reactor is located close to the surface, the surrounding rocks are influenced by contemporary weathering under tropical conditions. Moreover, hydrothermal alteration took place in the period of criticality. To determine the effects of such alteration processes on the behaviour of actinides and fission products and to understand the main geological and mineralogical parameters and mechanisms influencing the retention and/or migration of these elements, it is proposed to examine one drill-hole and a weathered profile. Therefore, detailed mineralogical, geochemical and petrographic analyses such as scanning microscopy, transmitted electron microscopy, X-ray diffraction analyses, ICP mass-spectrometry, thermo-ionization mass spectrometry and gas mass spectrometry will be performed .
