摘要：
Intense and purposeful predictive metallogenic and prospecting studies conducted in the Russian part of the Baltic Shield and in the territory abroad lead to discoveries of uranium and complex uranium deposits of different types: unconformity, "sandstone" (bitumen-uranium), quartz-pebble conglomerates, veins, etc., as well as numerous ore-showings, and anomalies. Among numerous ore types of uranium and complex uranium mineralization the most promising are uranium-precious-metals-vanadium ores of fold-fault zones (Srednyaya Padma) formed during the Svecofennian tectonomagmatic activation (TMA) and uranium unconformity-type ores in the vicinity of the Pre-Riphean structural-stratigraphic unconformity (SSU) in the Pasha-Ladoga Graben (Karku) and pre-Vendian SSU (Slavyanka, Ryabinovsky). The role of pre-Early Proterozoic SSU to which numerous ore-showings are confined (Palozero-1, Pachtavuoma and others), are at present underestimated.
