Talysh is a structural zone on NE flank of Elburs folded system confined to area of its subsidence on NW in conjuga-tion with the Lesser Caucasus. Among Eocene magmatic complexes of Central Iran and Elburs represented by differ-entiated calc-alkaline and subalkaline series of islandarc system Talysh structure can be determined by subalkaline and alkaline compositions of basalt magmatism, which are differed by material characteristics from “islandarc” types. Genetic connection of complexes with various series in space-time association is still unsolved. By study of petro-geochemical parameters complex the problem has been con-sidered for primary magmas origin for them which are char-acterized by combination of “riftogenic” and “islandarc” geochemical features. There is a connection with geodynam-ics of region.
