石制品后埋藏微痕的实验研究述评

A Review on Experimental Wear Analyses of Lithic Artifacts Suffered from Post-Depositional Processes

石制品经使用废弃后会经历漫长的后埋藏过程,在这个过程中石制品表面可能会产生和人类使用痕迹相似的微痕。关于石制品表面的后埋藏微痕实验研究,是通过实验模拟石制品的埋藏环境与过程,观察石制品表面因此而产生的后埋藏微痕,将之与使用微痕进行对比,从而更好地区分二者。当前有关石制品埋藏的实验研究主要集中在土壤埋藏及扰动、水流搬运活动和踩踏行为三个方面,较为全面的后埋藏实验研究对于提高石器微痕分析的准确性有重要意义。

Lithic artifacts undergo some post-depositional transformations in the ground, which will cause ware similar to that caused by human behaviors. Experimental research on post-dcpositional wear is to simulate the environment and process in which the lithic artifact is deposited and to observe the traces that have been left on the artifact surface. Comparisons are made to distinguish the post-depositional wear from use wear. The existing studies on post-depositional wear of lithic artifacts have mainly focused on the three factors： soil compaction and creep, water transport, and trampling. More comprehensive studies are to be conducted to increase the accuracy of microwear analyses.
