摘要

影响微石器技术传播的地理和生态因素是南亚史前研究的关键焦点。本研究考察了位于印度东部恒河下游盆地(LGB)的Barakar和Susunia两个微石器遗址,并提供了Susunia新的放射性碳定年结果,为该遗址提供了绝对的年代学。初步分析表明,这些遗址以微岩屑组合为特征,其历史约为17000 - 12000年BP,对应于晚海洋同位素阶段(MIS) 2。人类占领的时期与气候变化相一致,其特征是印度夏季风(ISM)的主导地位和该地区的潮湿条件。虽然这两个地点共享核心片和叶片生产技术,但在岩石原材料使用方面的区域差异是明显的。值得注意的是,Susunia的发现,包括研磨/锤石,贝壳珠和微石器工具,为了解社区的文化习俗,生存策略以及与环境和邻近群体的互动提供了见解。这些结果强调了LGB中微石适应的技术和社会动态。尽管有这些贡献,进一步全面的田野调查和挖掘对于加深我们对该地区微石器技术和社会变革的进化轨迹的理解至关重要。

Understanding the Microlithic technology in the Lower Ganga Basin, Eastern India: A chronological and ecological perspective
The geographical and ecological factors influencing the spread of microlithic technologies are a pivotal focus of prehistoric research in South Asia. This study examines two microlithic sites, Barakar and Susunia, located in the Lower Ganga Basin (LGB) of Eastern India, and presents new radiocarbon dating results from Susunia, providing an absolute chronology for the site. Preliminary analyses reveal that these sites, characterized by microlithic assemblages, date back approximately 17,000–12,000 years BP, corresponding to the Late Marine Isotope Stage (MIS) 2. The period of human occupation aligns with climatic shifts marked by the dominance of the Indian Summer Monsoon (ISM) and humid conditions in the region. While the two sites share core-flake-based and blade production techniques, regional divergences in lithic raw material usage are evident. Notably, findings from Susunia, including a grinding/hammer stone, shell bead, and microlithic tools, provide insights into the community’s cultural practices, subsistence strategies, and interactions with their environment and neighboring groups. These results underscore the technological and social dynamics of microlithic adaptations in the LGB. Despite these contributions, further comprehensive fieldwork and excavation are essential to deepen our understanding of the evolutionary trajectory of microlithic technologies and societal transformations in the region.
