Uranium potential of the Central-Siberian area
This article describes main uranium regions of Central-Siberian area and allocations of main types of uranium mineralization, including an ore run parameters and resources. It is shown that the most attractive uranium deposits for exploration are those sandstone-type in the Mezozoic-Kainozoic sediments and those of unconformity-type in pre-Cambrian rocks. Unconformity-type deposits are associated with big Archean-Proterozoic tectonic protrusion of the basement. Sandstone-type deposits have been found in the selvage of West-Siberian plate and they are connected with the oxidized zones. It has been noted, that Stratiform sulfidic uranium ore runs of the main interest. They have the first kilometers of length in the Devon-Carbon sediments of Paleozoic depressions in Tuva and Minus. These deposits can be deemed as objects for open cast mining or for ISL by junior companies
