中国北方旧石器时代晚期石器工业最明显的改变就是细石叶工艺的出现,精致规整的细石核、细石叶代表了打制石器的巅峰水平。即使是现在,考古学家们有上佳的原料、良好的工具以及积累多年的研究经验为基础,仍然需要相当的训练才能掌握复制的技巧。就现有的研究而言,复制细石叶的生产过程已经为考古学家们所掌握~([1,2])。技术类型学的研究经过五十余年的发展也已相当深入,运用复制和石制品的拼合可以重建细 The most obvious change in the stone industry in the late Paleolithic period in northern China was the appearance of fine stone leaves. Fine fine-grained fine-stone nuclei and fine stone leaves represented the highest level of stone-making equipment. Even now, archaeologists, based on good ingredients, good tools, and years of research experience, still need considerable training to master the techniques of copying. In the case of existing research, the production of fine stone leaves has been mastered by archaeologists ~ ([1,2]). After more than 50 years of research in typology of technology has also been quite in-depth, the use of replication and stone products can be reconstructed thin
