近日，山西省考古研究院对外公布了山西省晋城市阳城县析城山旧石器遗址的发掘资料。该遗址出土石制品494件，为研究黄河流域晚更新世晚段史前人类 石器技术和行为添新材料。析城山遗址是山西南部又一处旧石器时代晚期遗址，记录了该时期人类在较高海拔处（1800~1700米）的适应性行为。 据了解，析城山是中华上古名山，是华北罕见的亚高山草甸。析城山位于山西、河南两省交界处，是中条山脉东段主峰，海拔1888米。山体由奥陶纪马家沟 组石灰岩组成。因陨石碰撞或喀斯特地貌发育等原因，析城山山顶形成了一处高山洼地，洼地内披覆亚高山草甸，与周边丛林植被形成巨大反差。 2006年3月底到4月初，山西风光旅游规划设计院在阳城析城山一带考察时发现了细石器遗存。2020年北京师范大学历史学院考古学专业在此进行了调查，并 对娘娘池西侧一处剖面进行了试掘，出土千余件旧石器时代晚期早段的小型石片石器，也发现一些细石器，但均系地表采集。2022年5—8月，为探明细石器 遗存在析城山的分布，山西大学考古文博学院联合晋城市博物馆、阳城县文物博物馆对析城山遗址进行了正式调查与发掘。 析城山遗址石制品 析城山遗址的细石器产品以船型石核为代表，与其西北20千 ...

Core Insights - The excavation of the Xicheng Mountain site in Shanxi Province has yielded 494 stone artifacts, providing critical new materials for studying the evolution of stone tool technology, survival behaviors, and adaptation strategies of prehistoric humans in high-altitude environments [1][2] Group 1: Excavation Findings - The site was first discovered in 2006 at an altitude of 1888 meters, with systematic excavations conducted from May to August 2022 by Shanxi University and local cultural heritage institutions [1] - Artifacts are categorized into two stratigraphic units: the lower layer contains 35 pieces dating back approximately 28,000 years, while the upper layer has 459 pieces from a slightly later cultural period [1] Group 2: Material and Cultural Insights - The majority of the stone artifacts were made from high-quality black flint, sourced from a location about 30 kilometers north of the site [1] - The site features a distinctive stone tool type known as boat-shaped cores, which share cultural similarities with the nearby Xiaochuan site, indicating a connection in fine stone tool technology [1][2] Group 3: Research Implications - The new findings from the Xicheng Mountain site contribute significantly to the understanding of fine stone tool culture in the Qinhe River basin, shedding light on the migration patterns of late Pleistocene humans and their adaptation to high-altitude environments [2]
