Geological commercial evalution of ore existence of dictyonema shales and obolus sandstones of the Baltic sedimentary basin

Dictyonema shales and obolus sandstones (phosphorites) of Baltic sedimentary basin are promising geological-industrial type ores containing different concentration conditions meet the rare and scattered, rare earth, radioactive, non-ferrous, precious metals. The technique of a geological and economic estimation of their expected resources is offered and the potential cost of expected stocks is calculated.
Key words: geological and economic estimation, Baltic sedimentary basin, dictyonema shales, obolus sandstones (phosphorites).
