The Qingciyao
paleolithic site,an important early paleolithic site in Shanxi Province, was discovered in the spring of 1975
and excavated twice in 1976 and 1977 respectively. The previous (report) of excavation was published in 1983. In 1984 and 1987, some stone artifacts including cores, flakes and tools, were discovered again. Most of stone materials are quartzite, and a few are quartz and flint. Direct hammer flaking was mainly employed on cores with
alternate percussion, and bipolar flaking was used occasionally. The flakes are dominant in the assemblage, and some flakes with scarred platforms and with prepared platforms are identified for the first time. All of stone tools are scrapers and trimmed predominantly by hard hammer on flakes. Some scrapers were crudely trimmed in the alternate ways. The majority of the retouch (occurred) on the dorsal surface of the scrapers by simple and crude percussions, some scrapers retain (various) degrees of cortex. The types and techniques of the Qingciyao assemblage are similar to those of the early
Paleolithic sites in North China .It provides new materials to study Qingciyao culture.
