A Preliminary Report on Xiaopingan Site,in Jixian, Tianjin Dated to Paleolithic Period

小平安旧石器地点于2005年4月发现,5月又对其进行了复查。该地点位于天津蓟县的河流阶地内,在其土黄色黏土质粉砂和地表发现石制品31件,包括石核、石片和工具;原料以石英砂岩为主。古人类选择地点附近的阶地底部河卵石为原料进行剥片和加工石器;硬锤锤击法为剥片的主要技术;石制品总体以小型和微型居多;石器主要以石片为毛坯,刮削器是主要类型;石器多由古人类在石片的一侧采用锤击法正向加工而成。石制品特点显示中国北方石片工业的文化面貌。地貌与地层对比则显示遗址的时代大致属于晚更新世晚期,即旧石器时代晚期。
