The Kalistraticha III burial site in the system of Ob '-Yrtysh Seima-turbino phenomenon sites

The article is devoted to the research result of a new Seima-Turbino-type site named "Kalistraticha-III". The aim of the research is to recognize the place of burial rites and material complex in the system of the Seima-Turbino phenomenon from the Ob-Yrtysh region. There were some characteristic features of burial rites that could be observed in the Bronze Age burials of the same time: the burials on the tomb field were located in a row, elongated along the N-S line; the dead were buried in shallow pits, positioned on the left side, with their heads turned to the east. The data of the X-ray-fluorescence analysis of the spearhead from Kalistraticha-III site reveals that it was made from bronze mixed with a small amount of lead and zinc. The presence of copper-lead-zinc ores characterizes polymetallic deposits of the Ore Altai. Morphological analysis of the Seimino-turbine type spearhead from the Kalistratikha-III burial ground showed its difference from the classic spearheads found in the burial complexes of the Rostovka burial ground. This object was assigned to the Seima-Turbine tips group, which received the designation "Preobrazenskaya". The following characteristic features are distinguished for it: an ellipsoidal feather, with a maximum expansion in the central part; the "fork" of the tip occupies a small part of the pen, its teeth are often not parallel to each other, but converge on the central stiffener. To the present day, six bronze spearheads with similar morphological features are known. All of them originated from the forest-steppe Ob-Irtysh territory. Perhaps the morphological features of the Preobrazenskaya group of "forked" heads were formed in this territory. At present this group can be associated with the Odintsovo-Elunino antiquities of the second half of the 3rd millennium BC. The tips of the "Preobrazenskaya" group often originated from single burials on the burial sites. Similar situation can be observed on the of Preobrazhenka-6 and Kalistratikha-III sites. Such burials could signify a high social status of a specific person in a team, while classic "Rostovkino" ones could label an entire elite social group. The considered complex at the Kalistratikh-III burial ground replenishes the source fund for Seimino-turbine topical questions and reflects the local version of Seimino-Turbine bronze-casting traditions on the eastern periphery of their distribution.
