Abstract

The classifications of thorium mineralization which exist on the territory of the Union of Independent States are considered. Classification of thorium mineralization of Precambrian rocks of Ukrainian shield is offered. Five types of thorium mineralization are identified. They are: ultrametamorphic (magmatic) thorium mineralization which associates with granitoids; magmatic mineralization which associates with alkaline intrusions; metasomatic mineralization; hydrothermal one and terrigenous-clastogenic mineralization. Industrial prospects of identified genetic types are defined using the mineralization intensity factor.

 

Key words: genetic classification, complex ores of thorium, industrial prospects of thorium ores, thorium ore formations, intensity factor of mineralization.
