本文是对袁家山旧石器遗址黄土层中出土石制品的研究报告。遗址共出土石制品292件,类型包括砾石、石锤、石核、石片、工具、废品和赤铁矿,以废品和石片数量居多。原料以石英砂岩和石英岩为主,尺寸主要为小、中型,工具组合包括较多刮削器、雕刻器和少量重型刮削器,锤击法为主要剥片和加工方法,砸击法偶有使用。其石制品特征可归属为早期石片石器工业。根据近年对第四纪剖面堆积序列和晚更新世相关环境的研究,该遗址时代为旧石器时代晚期。袁家山遗址黄土层中石制品的发现填补了澧水流域旧石器地层序列中的缺环,为我们了解其石器技术及人类行为提供了重要的实物资料。
This article is a research report on stone products unearthed in the loess layer of Yuanjiashan Paleolithic site. A total of 292 pieces of stone products were unearthed at the site, of which gravel, stone hammer, stone core, stone tablet, tools, waste products and hematite were the major types of waste products and stone chips. Raw materials mainly quartz sandstone and quartzite, the size is mainly small, medium-sized, the combination of tools include more scrapers, engravers and a small amount of heavy-duty scraper, hammer method as the main stripping and processing methods, smashing method used occasionally. The characteristics of its stone products can be attributed to the early stone stone industry. Based on recent studies of the Quaternary sedimentary sequence and the late Pleistocene environment, the site was dated to the late Paleolithic. The discovery of stone products in the loess layer of the Yuanjiashan site fills in the missing ring in the Paleolithic sequence of the Huangshui River Basin and provides important physical data for us to understand its stone technology and human behavior.
