摘要:

位于汉水左岸一级支流金水河第四级阶地的金水河口遗址是汉水流域发现较早的一处旧石器遗址。2014年6月~2015年2月,为了配合国家重点建设工程——南水北调西线“引汉济渭”项目的实施,我们对金水流域金水镇附近的3个旧石器遗址进行了正式发掘,金水河口遗址即为其中之一。该遗址发掘面积370m2,出土不同类型石制品1210件。研究显示在金水河口遗址生活的古人类主要选取附近河滩砾石为原料进行剥片及工具加工。石制品的岩性以石英和石英岩为主,硅质灰岩次之,并少量使用了石英砂岩和花岗岩原料。古人类主要使用锤击法剥片。遗址中石核的利用效率较低,近半数石片有直接使用的痕迹。加工工具的毛坯以石片为主。工具类型除了刮削器、凹缺器、石锥等小型工具之外,还有砍砸器、手镐、重型刮削器等重型工具。遗址中碎屑数量很少。石制品组合以刮削器等小型工具为主,也包含少量重型工具。相较于汉中盆地已发现的遗址,金水河口遗址的文化面貌与洛南盆地中更新世的龙牙洞遗址更相似,但是重型工具的比例更高。由于遗址堆积物已超出了钾长石红外后释光测年法(post-IR IRSL)的测年范畴,目前只能给出遗址的埋藏时间下限,即埋藏石制品地层的年代不晚于150 ka。作为汉中盆地有明确测年的中更新世晚期遗址,金水河口遗址为我们系统了解汉江支流金水河流域和秦岭地区的石器工业特点、遗址地层堆积及年代等提供了新的、丰富的材料。

Abstract:

The Jinshuihekou site, discovered in the 1980s, is located in the southern piedmont of the Qinling Mountains. This site is on the fourth terrace of the Jinshui River, a left tributary of the Hanjiang River in central China. From June 2014 to February 2015, three Paleolithic localities, including the Jinshuihekou site, were excavated near Jinshui town as part of the national key construction project: the Western Route of the South-to-North Water Diversion Project, also known as the “Hanjiang River to Weihe River Water Diversion Project”. An area of 370m2 was excavated yielding 1210 stone artifacts. The early hominins at this site mainly selected cobbles/pebbles from fluvial gravels for tool knapping; predominately made from quartz and quartzite, followed by siliceous limestone, quartzite sandstone and granite. The principal flake knapping method is hard hammer percussion, and considerable components of the artifacts still retain features of its original use without the need for modification. Analyses of the lithic assemblage indicate that the retouched tools are comprised of small tools made on small flakes such as scrapers, notches, awls, and heavy-duty tools such as choppers, picks, and heavy-duty scrapers. The characteristics of the lithic assemblage resemble the Longyadong Middle Pleistocene cave site in the Luonan Basin in the southern Qinling Mountains but with higher proportion of heavy-duty tools. Based on the post-IR elevated temperature IRSL(pIRIR 290°C) dating method, the layer which buried stone artifacts at Jinshuihekou is earlier than 150 ka. The Jinshuihekou site restore the missing part of the Paleolithic cultural sequence in the Hanzhong Basin and provides new materials for studying the behavior and Paleolithic technology of hominins in the catchment of the Jinshui River and the Qinling Mountains region.
