洛南盆地槐树坪旧石器地点最初发现于1999年,该地点位于南洛河左岸(北部)支流石门河及石门河的二级支流东麻坪河(石门河一级支流为麻坪河)之间的第四级阶地上,是洛南盆地高阶地旷野旧石器地点群的代表性遗址之一。2004年4~5月和2006年6~7月,槐树坪地点曾历经两次小规模试掘。2013年4~6月,我们对该遗址进行了较大规模的系统发掘,发掘面积56 m~2,出土石锤、石料、石核、石片、工具、断块、碎屑等不同类型石制品830件。本文对2013年发掘出土的石制品进行了初步研究,统计分析结果显示,槐树坪地点加工石制品的原料来自遗址附近河流阶地砾石层中的砾石,其中以石英和石英岩为主,石英砂岩和细砂岩也有使用。剥片方式主要采用锤击法,偶见砸击法和碰砧法。石制品以中型和小型为主。工具多为石片加工而成的刮削器,偶见手斧、薄刃斧、石刀等大型工具。石器加工方向以正向居多。光释光测年数据表明,槐树坪地点埋藏石制品地层堆积物形成年代大约为距今8~9万年到1.3万年之间,其中7~8万年段的地层堆积物中包含石制品较多。槐树坪地点发现的石制品丰富了洛南盆地旧石器遗址的材料,可以使我们更深刻的了解洛南盆地高阶地旧石器遗址群的地层埋藏情况、遗址年代和石器工业内涵。
The locality of the Huashuping Paleolithic in the Luonan Basin was originally discovered in 1999 and is located at Dongmaping River, a tributary of the Shimen River and the Shimen River, on the left bank of the Nanlu River (northern part) (Maping River, a tributary of the Shimen River) Between the fourth terrace, is one of the representative sites of Paleolithic sites in the Luoyang basin high-level wilderness. From April to May of 2004 and from June to July of 2006, Huai Shuping sites have undergone two pilot excavations. From April to June 2013, we systematically excavated the site to a large scale and unearthed 56m ~ 2 unearthed different types of stone such as stone hammer, stone, stone core, stone tablet, tool, broken block and debris Products 830 pieces. This paper conducted a preliminary study on the excavated stone products in 2013. The statistical analysis shows that the raw materials of the processed stone products at the Huashuping site come from the gravels in the gravel layers of the river terraces near the ruins. Quartz and quartzite are the main materials, quartz sandstone And fine sandstone is also used. Stripping method is mainly used hammer method, occasionally smash hit and touch anvil method. Stone products to medium and small mainly. Tools and more for the stone processing scraper, occasionally ax, thin blade ax, stone knives and other large tools. Stone processing direction to the majority of positive. Photoluminescence dating data show that the formation of burial rock products at the Huai Shuping site is about 80 to 90,000 years old and 1.3,000 years old. Among the 80,000 to 80,000 years, the stratigraphic deposits contain stone More products. The stone products found at the Huashuping site enriched the materials of Paleolithic sites in the Luonan Basin, enabling us to understand more deeply the burial conditions of the Paleolithic ruins in the Luonan Basin, the sites and the connotation of the stone industry.
