The effort of the work is aimed at finding regularities for location of the occurrence of metal and non-metal minerals (rare, ferrous, radioactive and precious metals, phosphorus, graphite, titanium, ceramic raw materials etc.) that have formed during Proterozoic orogeny. The goal is to delineate areas of the Ukrainian shield promising for further exploration based on the developed geochemical, petrological and geophysical criteria of prospecting.

The reconstructed geodynamical settings and locations of ore-bearing metasomatites and differentiated intrusions with which deposits and occurrences of  rare, precious, radioactive metals, phosphorus,  titanium and other commercial minerals are spatially and genetically related allowed delineating a definite metallogenic zonation within east (Azov Region), central (West Ingulets-Krivoi Rog-Kremenchug suture zone, Ingul megablock, Golovanevsk suture zone) and west (Nemirov-Kocherov suture zone) parts of the Ukrainian Shield (USh).

Integrated criteria to evaluate ore potential (geochemical, petrological and geophysical) of the suture zones and megablocks of the USh are proposed. Based on these criteria evaluation of concrete and potential orebearing ability of Proterozoic igneous complexes and availability of the well-known rare-earth deposits and geochemical anomalies is made. The cause of its formation is investigated

Promising metallogenic zones, areas and ore clusters within megablocks of the USh are predicted.

Economic potential is expected from scaling the scope of drilling by concentrating geological prospecting at the areas promising for commercial minerals exploration.
