The hydrothermal-metasomatic formations in the sedimentary rocks examined formed in two phases. During the metasomatic phase, mineral associations of the metasomatites formed: chlorite-carbonate, anthraxolite-apatite-albite, and carbonate-sericite; and in the veinlet phase: pyrite-sericite, rutile-pyrite, sulfide-ankerite, barite-calcite, calcite-albite, and dickite-kerite. The uranium mineralization consists of uranotitanate, pitchblende, and a uraniferous apatite, the formation of which has been associated with metasomatic changes in the surrounding sedimentary rocks. Uranium mineralization is not characteristic of the veinlets. In the metasomatites, uranium mineralization is unevenly distributed. Pitchblende and uranotitanate have been concentrated on the sites of development of the chlorite-carbonate mineralization, and the uraniferous apatite is associated with the anthraxolite-apatite-albite mineralization.
