[en] Conclusion: Since the Fukushima nuclear power plant accident in 2011, many mining companies are not interested in uranium. It leads to the decrease in uranium spot price and the delay of IMOURAREN Project. Only, 47 exploration licenses for 12 mining companies are now valid in Niger.
[en] Moer and more evidence indicates that there are multi-stages uranium mineralization in many granite-related uranium deposits in south China. The early stage mineralization shares the characters of hypothermal U mineralization and had close relations to alkaline alterations.
[en] Classifications of uranium deposits follow two general approaches, focusing on: • descriptive features such as the geotectonic position, the host rock type, the orebody morphology, …… : « geologic classification »; • or on genetic aspects: « genetic classification »
