East Asian belt of leucogranite-type uranium deposits

Belt of widespread highly radioactive Mesozoic leucocratic granite and related uranium deposits is traced all along the eastern margin of Eurasia. It is confined to submeridional chain of activated synform nuclears at the base of cis-Pacific paraplatforms and located in a subduction zone, which controls its energy and ore contend in the Mesozoic. All uranium provinces of the ore belt are characterized by close paragenetic association of leading leucogranite type with volcanite and sandstone types.
Key words: ore belt, nuclear, leucogranite, volcanics.
