Fault Permeability and Active Hydrothermal Systems: A Key to Infer the Formation of Unconformity-Related Uranium Deposits from Athabasca Basin (Canada)

@inproceedings{milesi:hal-05245985,
 abstract = {The Athabasca Basin region (Saskatchewan, Canada) hosts the highest grade and among the largest tonnage uranium deposits in the world. The formation of unconformity-related uranium (URU) deposits was essentially triggered by intense fluid circulations at the basin/basement interface that were channelized in a complex fault network. The development and the geometry of the fault systems had a first-order impact on the location and the size of uranium deposits. The intense fluid/rock interaction which affected that environment more than 1 Ga ago, however, strongly limits the characterization and quantification of these critical parameters. To overcome this problem, physical properties of fault systems and natural flow rates from active hydrothermal systems available in open databases have been used to define the possible range of values associated to fault permeability and fluid flow in the forming context (geometry/timing) of URU deposits.},
