Signs of participation of uranyl-fluorides in the formation of rich uranium ores of the Streltsovskoe-type deposit, Eastern Transbaikalia

Huge resources of uranium and a significant por tion of rich ores are unique peculiarities of the Strelts ovskoe ore knot [1]. The origin of rich ores is debat able, and the structural factor is of key importance [2]. The ore formation is related to hydrothermal uranyl carbonate complexes [3], which extracted uranium from granites of the basement [4]. However, this model is not universal. The authors accept the concept of the relationship between the Streltsovskoe type deposits and basaltrhyolite volcanism with active participation of fluorine (fluorite) in the processes of ore formation.
