This paper aims to reconstruct the general knapping scheme in the Katta Sai 1 assemblage dated to around 40 kya. The site was excavated within a large -scale fieldwork project of interdisciplinary studies on Middle Paleolithic settlements in the western Tian Shan piedmont. The technological analyses allow the identification of a new variant of human adaptation in the regional Middle Paleolithic. The locally -collected river pebbles were knapped using a predetermined Levallois core reduction scheme. Although some volumetric features can be identified within the assemblage, the technology differs from the other well -known sites in the region, such as Obi -Rakhmat of Kulbulak, where blade technology predominates.

本文旨在重建大约40 kya的Katta Sai 1组合中的一般绑架方案。该遗址是在西天山山麓中部旧石器时代定居点的跨学科研究的大型野外工作项目中开挖的。通过技术分析，可以确定中古石器时代人类适应的新变种。使用预定的Levallois岩心缩小方案将当地收集的河卵石打碎。尽管可以在组合中识别出一些体积特征，但该技术不同于该地区其他知名站点，例如刀片技术占主导地位的Kulbulak的Obi -Rakhmat。
