Case study of polymetallic and lead-zinc deposits in Azerbaijan demonstrated the influence of deep rocks on the material composition of ores. During the formation of a magmatic centre within the granitic layer, there have been formed properly lead-zinc deposits, during the formation of sources at big depth: in mantle or in the lower earth crust, within the basalt layer-copper-pyritaceous, copper-porphyric etc. During the displacement of magma into the upper layers there occurs assimilation of acid rocks and enrichment of magma by elements of the granitic layer, in particular, by lead and there have been formed polymetallic, copper-zinc-lead deposits
