Exploration and identification of primary and secondary uranium and thorium enrichments can be facilitated by the μ-energy dispersive X-ray fluorescence (EDXRF) technique that allows the high resolution,
in-situ
, multi-element determination at the microscopic scale (10 to 100µm). EDXRF analysis is fast and useful for the identification of unconventional uranium and thorium deposits, the localisation of primary uranium and thorium minerals as well as secondary uranium- and thorium-bearing phases. A current project aims at the siting of uranium and thorium mineralisation in ores from the Witwatersrand Au (uraninite), Vergenoeg Fe-F (uraniferous monazite), and Palabora Cu (uranothorite) deposits.
