The Amu-Darya Delta (ancient Khwarazm, modern Uzbekistan) was a borderland between northern steppe-based Andronovo-Srubnaya groups and southern oasis cultures in the Late Bronze Age. The local sites are known as the Tazabag'yab culture, of which Kokcha 3 is the largest excavated burial site. As such, Kokcha 3 provides the largest representative record of the local burial customs for this era. Scholars have documented a complex burial ritual for males, females and two types of double burials and reconstructed two chronological phases at the site. However, a study incorporating these different sources is still missing.

In this paper, the anthropological and archaeological record of Kokcha 3 is studied using multivariate statistical approaches and spatial distribution patterns. The burial ritual was most likely divided according to gender. Double burials are distinguished between simultaneous and consecutive burials, which include different demographics and are likely to be used in different contexts. On the excavation plan, three separate areas for males, females and double burials can be reconstructed. The two-phase chronology model is verified using correspondence analysis, establishing the funeral pottery as chronological marker at Kokcha 3. Conclusions about the prehistoric landscape are drawn from the results and a hypothesis on the social structure of the Kokcha 3 community is proposed considering the context of a borderland situation. The results presented may also be relevant for the interpretation of the archaeological record of the Late Bronze Age in other regions in south Central Asia.

阿姆河三角洲（古代花剌子模，现代乌兹别克斯坦）是青铜时代晚期以北部草原为基地的安德罗诺沃-斯鲁布纳亚群落和南部绿洲文化之间的边界。当地遗址被称为 Tazabag'yab 文化，其中 Kokcha 3 是最大的挖掘墓地。因此，Kokcha 3提供了这个时代当地丧葬习俗的最大代表性记录。学者们记录了男性、女性和两种双重葬礼的复杂葬礼，并在该遗址重建了两个年代阶段。但是，仍然缺少包含这些不同来源的研究。

在本文中，使用多元统计方法和空间分布模式研究了 Kokcha 3 的人类学和考古学记录。葬礼很可能是按性别划分的。双重埋葬区分同时埋葬和连续埋葬，其中包括不同的人口统计数据，并且可能在不同的环境中使用。在挖掘计划中，可以重建男性、女性和双葬三个独立的区域。使用对应分析验证了两阶段年表模型，将葬礼陶器确定为 Kokcha 3 的年代标记。从结果中得出关于史前景观的结论，并根据上下文提出关于 Kokcha 3 社区社会结构的假设的边境局势。
