Abstract: The paper is a brief study of geology, geomorphology and description of characteristicsof stone assemblages of Gujiao. Gujiao located on the east slope of the Luliang Mountain is amountainous basin in upper reaches of the Fenhe river. Since 1983, we have surveyed the areaand found Wangjiagou, Changyugou, Fenghu angyan andHouliang paleolithic sites on thesouthern bank of the Fenheriver.Those sites and Gugang sitefound in 1959 belong toearly, middle and late paleolithic age respectively. The stone artifacts of Wangjiagou were laidin the lower gravel layer of Lishi Loess.Up till now, the layer is the most ancient one bea-ring stone artifacts in Gujiao region and its geological age may belong to early middle Plei-stocene· Ninety- five percent of the stone artifacts found in the above mentioned five paleolithicsites were made of hornfels in old terraces. Main type includeschoppers and scrapers, heavyprismatic point etc. The flake tools coexist with the pebble tools. All stone artifacts are large insize.Broadly speaking, they belong to the tradition of "large flake choppers- -heavy prismaticpoint. The main characteristics of the stone artifacts found fromGujiao are comparablewith those of Dingcun, Kehe, Liangshan sites. Rich cultural remains of paleolithic sites in Gu-jiao region will play an important role in further study of the origin and development of the culture represented by heavy prismatic point.
