| 摘 要： | 楼房子遗址系陇东地区一处旧石器时代中期的旷野遗址。2018年对楼房子遗址下文化层下部（第14、15层）进行了发掘,发掘面积为16 m2,出土大量石制品、动物化石。石制品原料以石英砂岩和硅质灰岩为主,类型包括石核、石片、石器、断块或断片、备料等。剥片采用硬锤锤击法,石器修理以硬锤锤击法为主。石制品类型和技术总体上属于北方小石器传统。结合地层堆积及相关的孢粉分析初步认为,楼房子遗址下文化层时代与MIS5相当。

| Abstract: | The Loufangzi site, located in the eastern Gansu province, is an open-air site dated at the middle paleolithic. In 2018, excavations were carried out on the lower part of the cultural layer (Layer 14 and 15) of the Loufangzi site, and plenty of artifacts and animal bones were discovered in 16 m2. Lithic raw materials were made of gravel from river nearby, which were mainly quartz sandstone and siliceous limestone. The lithic assemblage includes cores, flakes, tools, chunks etc. The principle ?aking technique was direct hard-hammer percussion. Most of tools were retouched by hard-hammer. The typological and technological characteristics of artifacts from the lower cultural layer of the Loufangzi site belonged to the small tool technology. Combined with the stratum accumulation and related pollen analysis, we preliminarily think that the age of lower cultural layer of the Loufangzi site is equivalent to MIS5. |
