IN recent years (1986-1996), many deposits, ore occurrences and numerous haloes of ore mineralization connected with low temperature alterations have been revaled and studied in the eastern part of theSiberian plate. It is established that all of them are located either in a zone of structural-stratigraphic unconformity (SSU) and above this zone, on different levels of stratified volcanogenic, terrigenic and carboniferous units. Most of the ore occurrences are situated on the territory of the Ulkansky and UchurskyProterozoic basins (see figure 1).
