Three complexes of the Bronze Age have been studied in the II burial mound near the village Vtoroe Imangulovo II in the Oktyabrsky district of the Orenburg region. These include: the Volga-Ural post-catacomb time, the Abashevo and the Srubnaya–Alakul time. The population that left them chronologically changed sequentially. It has been established that the burial of the Volga-Ural cultural group was performed at the turn of the middle and late periods of the Bronze Age, the Abashevo burial – at the beginning of the Late Bronze Age, and the Srubnaya–Alakul burial belongs to the period of the rise of the Late Bronze Age. The burial complexes with post-catacomb and the Abashevo cultural attribution are rare for the territory of the Western Orenburg region, as well as for the whole Volga-Ural region. Meanwhile, these formations played an important role in the cultural genesis of the Late Bronze Age of the region, so their timely publication seems relevant.
