【摘要】 2022年7月和2023年2—3月，云南省迪庆州维西县旧石器考古调查共发现旧石器遗址7处，采集石制品94件。遗址主要分布于金沙江流域腊普河和澜沧江流域永春河沿岸。石制品类型包括石核、石片、工具和断块等，原料以砂岩、燧石及各类火成岩为主。剥片技术以锤击法为主，砸击法和压制法也有使用。工具类型多样，包括刮削器、凹缺器和锯齿刃器等。多数遗址的石器技术面貌相似，以权宜性剥片的中小型石核-石片产品和石片石器为主，但也发现有典型的细石核产品，表明该地区同时存在细石器技术。本次调查对各洛洞遗址进行了简单剖面清理和初步光释光测年，结果显示遗址年代为距今3.4万—1.1万年，处于旧石器时代晚期。维西县旧石器遗址的发现，不仅将该地区人类活动历史推至旧石器时代晚期，也为厘清早期现代人在青藏高原东南缘地区的石器技术与适应策略，以及旧石器时代晚期高原人群与相对低海拔地区人群之间的迁徙扩散与交流互动关系提供了重要材料。更多还原

【Abstract】 In July 2022 and February–March 2023, joint Paleolithic archaeological surveys were launched in Weixi Lisuzu Zizhixian, Yunnan Province. During the survey, 7 new sites have been discovered with 94 lithic artifacts collected. Sites were mainly distributed on the bank of the Lapu River of the Jinsha River drainage and the Yongchun River of the Lancang River drainage. Cores, flakes, tools and chunks are included in the lithic assemblage, the raw materials are mainly sandstone, chert and igneous rock. The collected tools are of diverse types such as scrapers, notches and denticulates. Among most of the sites, the artifacts are mainly expedient small and medium sized core-and-flake products and flake tools, while typical microblade core products also presented, implicating that microlithic technology emerged in this region. In the survey, only the profile of Geluodong Site is basically cleared and fundamentally dated, the 34-11ka BP OSL age indicated that the upper layers of the site were at the Upper Paleolithic time. The findings of Paleolithic sites in Weixi County not only determine the human activities in this region started from Upper paleolithic, but also provide important materials for elucidating early modern humans’ lithic technology and survival strategy in the southeastern margin of Tibetan Plateau, as well as the dispersal and interaction of populations in plateau and those in relatively lower altitude areas.更多还原
