Abstract: | On the basis of detailed fieldwork and analytical procedures (microprobe, X-ray diffraction, chemical analysis, etc.), ores
and altered wall-rock rocks of the Khadatkanda and Etyrko deposits in the Kodar-Udokan mineragenic zone were studied. Economic
concentrations of gold and some other accompanying metals have been established in ore of the Khadatkanda uranium deposit
in the Syul’ban uranium district. REE-U lodes with brannerite-uraninite have been found at the Etyrko Fe-Ti-V deposit related
to the Chinei layered pluton in the Udokan mining district. The outlook for the discovery of new types of economic uranium
deposits is substantiated with respect to the known hydrothermal uranium ore objects and nontraditional setting related to
the layered mafic-ultramafic intrusions. |
