Abstract: The paper described the quartz artifacts found in Shangyan cave near the Yiyuan county seat in Shandong province in 1981.The author made some imitations of the tools and carried out experiment in scraping pig skin, cutting meat, drilling on bones and a little limestone gravel with these tools. The use-wears of the experimental samples were observed by stereomicroscope (OLYMPUS SZH-151) and electron microscope. That the stone tools from the cave have been used to cut meat and drill on bones is confirmed by comparing the use-wears on them with that of experimental samples. According to the stratigraphic analysis of the cave the artifacts belong to the late Paleolithic culture.
