Аннотация:Uranium mineralization in the Kodar-Udokan zone was
discovered in 1950 in the rocks of the Udokan Supergroup
(the Chitkanda prospect). But new occurrences of uranium
mineralization were found in the rocks of the Chiney
pluton and surrounding rocks only in the beginning of the
twenty-first century. Mineralization is related to metasomatized
rocks and is represented by brannerite, uraninite,
and other minerals. Inside the Chiney pluton, many rare
earth minerals were found as well. In this chapter, we
report the first results (Gongalsky BI, Krivolutskaya NA,
