摘要

位于印度北方邦(Uttar Pradesh)和中央邦(Madhya Pradesh)交界处的史前遗址拉丘拉(Lahchura)出土了一组独特的卵石岩心,为研究后阿舍利石器技术提供了宝贵的见解。本研究分析了345件人工制品中的134个卵石岩心,以了解还原序列、剥落策略和技术趋势。对剩余的人工制品进行了检查,以评估组合的组成和整体性质。除了测量分析外,该研究还侧重于岩心的定性特征,揭示了用于去除薄片的各种策略。卵石岩心主要由石英岩和燧石构成,呈现单面剥落模式,大部分剥落来自皮质平台。一些岩心显示平行端片去除的证据,表明技术转向端片分离,可能作为微叶片技术的先驱。分析表明,岩心缺乏形态塑造和对称性,鳞片疤痕表明主要在1-5 cm范围内的鳞片被去除。值得注意的是,基于原材料的剥落技术的差异突出了技术特征的连续性和可能的创新。研究结果表明,这些核心反映了由当地资源的可用性和人类群体的技术知识驱动的适应策略。与印度次大陆和中国南方的类似文物进行比较,进一步强调了拉赫丘拉组合的区域和时间意义。这项研究提出,Lahchura卵石岩心可能代表了石器技术的一个插曲,介于阿舍利和微刃传统之间。

Revisiting the Lahchura pebble tool-complex in Uttar Pradesh, India: Technological insights and analysis
The prehistoric site of Lahchura, located at the border of Uttar Pradesh and Madhya Pradesh, India has yielded a distinctive assemblage of pebble cores that offers valuable insights into post-Acheulean stone tool technology. This study analyses 134 pebble cores from a collection of 345 artefacts to understand the reduction sequences, flaking strategies, and technological trends. The remaining artefacts were examined to assess the composition and overall nature of the assemblage. In addition to metrical analysis, the study also focused on the qualitative features of the cores, revealing various strategies used to remove flakes. The pebble cores, predominantly made of quartzite and chert, exhibit unifacial flaking patterns, with most flakes removed from cortical platforms. Some cores show evidence of parallel end-flake removal, suggesting a technological shift toward end flake detachment, potentially serving as a precursor to microblade technology. The analysis reveals a lack of morphological shaping and symmetry in the cores, with flake scars indicating the removal of flakes primarily in the size range of 1–5 cm. Notably, differences in flaking techniques based on raw materials highlight both continuity in technological traits and possible innovations. The findings suggest that these cores reflect an adaptive strategy driven by the availability of local resources and the technological knowledge of hominin groups. Comparisons with similar artifacts from the Indian subcontinent and Southern China further underscore the regional and temporal significance of Lahchura's assemblage.This study proposes that the Lahchura pebble cores represent a possible episode in the stone tool technology, between Acheulean and microblade traditions.
