The stone artifacts from the Nanshan locality,Liaoning Province

The Nanshan locality is located at Wudaohezi Village of Huanren County in Liaoning Province. 60 lithic artifacts were collected from the locality and 4 stratigraphic layers were identified, with the total thickness of nearly 10m. Some artifacts were unearthed from the second layer. The assemblage includes cores, flakes, tools and debris. Hornfels and quartz sandstone are the predominant raw materials, followed by quartzite and slate. Hard hammer percussion is the dominant technique for detaching flakes, and retouched tools are mainly manufactured on flakes. The blades and leafed point found in the locality are rare in this area.
