Abstract: 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.
