World Distribution of Uranium Deposits

In 1995 the International Atomic Energy Agency published a hard copy map of World Distribution of Uranium Deposits, in collaboration with the Geological Survey of Canada. The map was based upon an early version of the IAEA's uranium database UDEPO and displayed 582 deposits using a deposit classification scheme which has since been superseded. In 2018, the IAEA published a second edition of the map based on approximately 2,900 deposits from the 2016 version of the UDEPO database. The second edition of the World Distribution of Uranium Deposits map (2018, IAEA STI/PUB/1800) was intended to be a snapshot of the IAEA UDEPO database as of 2016, showing the broad global distribution of uranium deposits and genetic types. Since its publication, updates and refinements to UDEPO since 2020 have resulted in a vastly different database than the one that existed in 2016, having almost doubled in size with nearly 5300 deposits. This third edition of the World Distribution of Uranium Deposits presents new information, such as additional deposits, a broader range of deposit sizes, a revised deposit classification system and improved geological visualization information (see the map explanation, key, and legend for detailed information). The online PDF version also includes enhanced functionality with layers and query capability.
