Questions of synchronization, cultural affinity of Sintashta and Petrovka sites and their possible solutions

The paper is aimed to discuss problems of synchronization and cultural affinity of Sintashta and Petrovka sites. The author denies a possibility of complete synchronization of Sintashta and Petrovka sites. He believes that comparing Sintashta and Petrovka sites, we try to compare incomparable phenomen: materialized remnants of the history of a community of the Sintashta clans of miners, metal-makers, blacksmiths, foundrymen, on the one hand, and sites of a community of the Alakul pastoral cultures, on the other.
