During the undertaken studying in Etyrko\'s field of the Chineysky complex a significant amount of uranium minerals with the high maintenance of PbO and H2O and REE carbonates is revealed: kyurit (?); furmaryerrit (?) it (is most widespread); vandendrissheit (?) (rare). A characteristic carbonate-REE Ц sinkhizit-(Ce). Features of structures of phases: maintenance of PbO (15-20 and more mas. %) and 5-8 mas.% H2O, allows to diagnose, with the greatest probability, listed water lead-bearing hydroxides of uranium. In general, uranium minerals of the massif of Etyrko have a ratio: 50% uraninit+brannerit and 50% - UPb-hydroxides. Prevalence of the listed hydroxides probably, is caused by ancient age of the massif of Etyrko and/or duration and polystaging of formation of an uranium mineralization. Proceeding from ratios UPb-gidoksidov with other uranium phases, they are created during hydrothermal process, at late stages of mineralogenesis.
