Fluid P-T-X characteristics and evidence for boiling in the formation of the Phoenix uranium deposit (Athabasca Basin, Canada): Implications for unconformity-related uranium mineralization mechanisms

•Phoenix uranium deposit formed from basinal brines from the Athabasca Basin.•Mineralization took place at shallow burial.•Fluid boiling occurred during mineralization.•Faulting-boiling-ore precipitation are integrated processes related to mineralization.
