The Korgantas culture (c. 400-113 BCE) replaced the Tasmola culture in Central Kazakhstan.[2][3][4] It is used sometimes termed as the "Korgantas period" of the Tasmola culture.[3]
The tombs of the Korgantas period differ significantly from those of the earlier Tasmola, lacking dromos passageways, and being smaller, with animal sacrifices arranged near the head.[3] The burials are often covered with a chaotic assemblage of stones, and the dead were oriented to the East or the Northeast.[4] Many characteristics of these burials, especially the heads of sacrificed animals, are similar to those of early Hunnic burials.[4] In a recent study, various Korgantas period graves were carbon-dated to between 400 and circa 100 BCE cal.[4]
Genetically, the Korgantas period seems to mark an influx of Ancient Northeast Asians (Devils_Cave_N profile) in Central Asia.[5] Of four Korgantas individuals analysed in a recent study, three had about 50% Ancient Northeast Asians (Devils_Cave_N) ancestry combined with about 50% Central Saka ancestry (Tasmola_Pazyryk), while only one had a traditional Central Saka profile.[6] The Korgantas people may have resulted from immigrations from the eastern regions of Central Asia, and may have come from the Ordos region of northern China.[7]
The end of the Korgantas period is marked by the expansion of the Xiongnu. The Korgantas period is sometimes presented as the "later Korgantas phase of the early Hun period".[4]
^Gnecchi-Ruscone et al. 2021, Fitting models for the main IA groups using LBA sources, the major genetic shift with the “new” East Asian influx (DevilsCave_N-like) observed in the Middle IA outliers and Korgantas. (...) From the second half of the first millennium BCE, we detect a major genetic shift in a number of outliers that are interestingly linked with the emergence of the Korgantas culture that replaced the Tasmola in central Kazakhstan..
^Beisenov et al. 2016, "Specific features of burial structures and artifacts (Figure 3) suggest that the Korgantas are related to sites in the eastern regions of Central Asia, and that the population might have migrated from Ordos region of north China (Tairov 2006; Shulga 2011).".
