Abstrakt

Results of researches of petrographic and geochemical structure of dictyonema shales and obolus sandstones (phosphorites) of Baltic sedimentary basin and them metalliferous are presented. It is established that the concentration Re, Rb, Cs, Sc; Cu, Zn, W; Pt, Pd, Rh in dictyonema shales are at industrial level. Ore maintenances in shales V, Ti, Mo, U are confirmed. In obolus sandstones industrial concentration REE, MPG, W are established also. It allows to consider dictyonema shales and obolus sandstones as nonconventional complex ores of new type. The features of formation dictyonema shales and obolus sandstones and conditions of ore formation in them metals
