摘要
枣子坪旧石器遗址埋藏于三峡地区长江右岸的第Ⅱ级基座阶地内。 2 0 0 0和 2 0 0 2年经历了两次抢救性发掘 ,揭露面积 10 0 0m2 ,出土石制品 10 1件。石制品类型包括石器、石核、石片、石锤和断块等。古人类选取河卵石为原料进行剥片和加工石器 ;石器以中型为主 ,毛坯多为完整石片 ,刮削器是石器的主要类型 ;石器加工较简单 ,多数单向加工 ,且以正向为主。石器工业具有中国南方旧石器时代主工业鲜明特点 ,同时蕴含了向长宽等比小型化发展的趋势。地貌和地层对比显示 ,该遗址可能与井水湾遗址同时 ,属旧石器时代中期。
The Zaoziping Paleolithic site on the second terrace of the right bank of the Yangtze River, is located in the Xinwan village, Sanhe town, Fengdu county, Chongqing. The site was excavated in 2000 and 2002 as part of the salvage archeological project in the Three Gorges Region.Deposits of the terrace consist of 4 layers, more than 14 meters in thickness. The cultural remains were mainly unearthed from the 4^(th) layer, a layer of fine sands, 1m in thickness, 150—156m above the sea-level, distributed along the Yangtze River. Over 1000 square meters were unearthed during the two field seasons and 101 stone artifacts were unearthed.The stone artifact assemblage includes retouched tools (16), cores (19), flakes (56), stone hammers (1) and chunks (9). The general features of these artifacts are summarized as follows:1) The stone raw materials exploited at the site are locally available on ancient riverbeds. Silicarenite is the predominant raw material used for producing stone artifacts.2) The principal flaking technique at the site is direct hammer percussion without core preparation.3) Most of stone artifacts are medium in size.4) Major blanks for tools retouch are complete flakess (62.5%), followed by incomplete flakes and pebbles.5) Most of retouched tools are medium in size.6) Scrapers are the dominating tool types, followed by choppers and points.7) Modified tools appear to be retouched by direct hammer percussion mostly unifically retouched on the dorsal surface of a blank.The stone tool assemblage at the Zaoziping site shows the distinctive character of the Main Industry in South China. Geomorphological and stratigraphical similarities between the Zaoziping and Jingshuiwan site indicate that the two sites can be placed at the same age, i.e. about 80,000 aBP., which result to the Middle Paleolithic in China.
