2012年在日照黄泥梁遗址的调查、试掘工作中共获得石制品75件,其中试掘出土者71件,地表采集者4件。试掘石制品埋藏于黄土地层的古土壤层中,石制品个体较小,原料以闪长玢岩和脉石英为主,类型包括石核、石片、石器、断块等,属石片石器工业组合;地表石制品原料主要为燧石,类型有细石核、细石叶、端刮器等,属细石器工业组合。本次的调查、试掘确认了黄泥梁遗址的原地埋藏属性,肯定了遗址的发掘潜力和研究价值。黄泥梁遗址的发现和研究将推动山东旧石器考古研究的进展。
The Huangniliang site, found in 2006, is located in Rizhao City, Shandong Province. A preliminary survey was conducted in 2012, and two technological groups of lithic remains were collected including 75 stone artifacts. Among these assemblages, 71 were collected in situ from a buried loess layer and 4 from surface. The buried site contains three depositional layers, with a total thickness of nearly 6 meters. The sediments at the base are granite weathered crust; these give way successively to a loess deposit which yielded chipped stone; and then loess deposit with more granite particles. All the 71 stone artifacts were manufactured from local quartz and dioritic porphyrite coming from the outcrops and the valley around the site. In terms of the flaking strategy, this assemblage from the buried layer is clearly flake-based. Hard hammer percussion seems the dominant technique for detaching flakes, and the blanks are irregular in shape and size. Retouched tools are small in number, and are mainly sidescrapers manufactured on flakes. The stone artifacts from the surface are microblade cores and end scrapers belonging to components of microblade technology. This is similar to the old surface collections in southeast of Shandong Province. The new findings especially in situ artifacts will benefit to solve the long-standing problems such as the age of Paleolithic remains in Shandong Province in view of scarcity of sites with clear depositional context there. And future study with more excavated artifacts at this site will help us to understand the adaptation of ancient humans along coastal area in East China..
