Abstract The rock shelter of Oued Bousmane, located in the eastern Algerian highlands, presents a stratigraphic sequence of the Middle Stone Age. The site, which was discovered in 2006, produced a significant number of lithic artefacts that are primarily made of local flint. The aim of the paper is to present the results of a techno-economic study of the Mode 3 lithic industry. The analysis focused on the procurement of raw materials, the technology, and the cultural attribution of the assemblages. The analysis revealed a preferential management of raw material and several reduction methods including Levallois, discoid, and laminar. The typological composition clearly distinguished it from the classical Aterian as defined at Oued Djebbana. This finding reinforced the idea of inter-site variability in the Middle Stone Age industries of Eastern Algeria.

阿尔及利亚的中石器时代技术：Oued Bousmane 遗址 (Djebel Dyr) 的技术经济方法案例研究

摘要 位于阿尔及利亚东部高地的 Oued Bousmane 岩石掩体呈现出中石器时代的地层序列。该遗址于 2006 年被发现，出产了大量主要由当地燧石制成的石器制品。本文的目的是展示模式 3 石器工业的技术经济研究结果。分析的重点是原材料的采购、技术和组合的文化属性。分析揭示了对原材料的优先管理和几种减少方法，包括勒瓦卢瓦、盘状和层流。类型构成清楚地将其与 Oued Djebbana 定义的古典 Aterian 区分开来。
