出土石制品494件 山西一旧石器遗址发掘资料公布

Core Viewpoint - The excavation of the Xicheng Mountain Paleolithic site in Shanxi Province has revealed 494 stone artifacts, contributing new materials for the study of prehistoric human stone tool technology and behavior in the late Upper Paleolithic period along the Yellow River basin [1][7]. Group 1: Site Description - Xicheng Mountain is a notable ancient mountain located at the junction of Shanxi and Henan provinces, with an elevation of 1888 meters, characterized by a high mountain depression covered by subalpine meadows [5]. - The mountain is composed of Ordovician limestone and features a significant contrast between the alpine meadow and surrounding forest vegetation [5]. Group 2: Archaeological Findings - The site has yielded a representative type of microlithic products, specifically boat-shaped stone cores, which share cultural similarities with the nearby Xiaochuan site, indicating a connection in cultural heritage [7]. - The high elevation of the Xicheng Mountain site suggests it was a key activity area for microlithic populations, enhancing the understanding of their migration and adaptation to high-altitude environments during the late Upper Paleolithic [7]. Group 3: Research Significance - The new findings from the Xicheng Mountain site provide valuable insights into the distribution of microlithic technology and the activities of prehistoric human populations in the Qinhe River basin [7]. - The research contributes to a broader understanding of late Upper Paleolithic human behavior and their adaptability to diverse environmental conditions [7].
