楔形石核概念内涵与细石核分类初探

Defining wedge-shaped cores and classification of microblade cores

细石叶技术是晚更新世末-全新世早期在东北亚及北美地区流行的石制品生产技术,其中楔形石核技术的研究格外引人关注,在楔形石核的内涵和研究中,存在很大分歧。本文回顾楔形石核的研究历史,就目前楔形石核最为关键的分类标准和技术内涵问题,尝试运用操作链的理念,借鉴"概念型版"的思想,建立细石叶技术分类系统,揭示楔形石核技术的内涵。楔形石核与锥形石核、船形石核等的区别不仅仅是形态上的区别,而是整个制作理念上的区别,在此基础上,就细石叶技术在华北的扩散问题略作讨论。

Microblade technology was widely distributed in Northeast Asia and North America in the late Pleistocene and early Holocene and research on wedge-shaped core technology has been particularly abundant.This paper briefly reviews the history of research on wedge-shaped cores and then proposes a formal definition of that core type and a system of classification for microblade cores based on the cha?ne opératoire and mental template concepts.The differences between wedge-shaped cores and other microblade cores lie not only in variations in morphology,but also in the strategies of production.Based on our analysis,we propose that flake blank exploitation strategies played an important role in the diffusion of microblade technology in North China.
