辽宁桓仁南山地点的石制品

The stone artifacts from the Nanshan locality,Liaoning Province

辽宁桓仁南山旧石器地点发现于2011年4月,共获得石制品60件。石制品原料多为角岩和石英砂岩,采用锤击法剥片。石制品类型包括石核、石片、工具和断块。工具以片状毛坯为主,主要采用硬锤修理。南山地点发现的个别石叶和桂叶形尖状器在辽宁地区较为罕见。推测此地点的年代为旧石器晚期。

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.
