ABSTRACT

We present a trampling experiment aimed at evaluating the overall morphological modifications on stone artifacts discarded forming big piles of lithic materials like the ones in intensive quarrying contexts. In this experiment, in contrast with most of the many trampling experiments developed so far, we laid orthoquartzite and silicified limestone artifacts in a nine- layered pile that included cores, flakes, different tools, and chunks. In this research, we focused on breakage and analyzed fracture rates and fracture types. Also, we contrasted the metric characteristics of fractured specimens against the model proposed for trampling fragmentation potential. The preliminary analysis presented for edge damage considered amount, distribution, location, scars width and length, and the identification of pseudo-tools. Results suggest that trampling over lithic artifact piles – a hard, irregular, and highly dynamic substrate – produces very high frequencies of modifications in lithic artifacts especially edge damage, including the production of pseudo-tools.

评估采石场岩体组合裂缝和边缘损伤的践踏试验

摘要

我们提出了一个践踏实验,旨在评估废弃的石制品的整体形态变化,这些石制品形成大堆石料,如密集采石环境中的石器。在这个实验中,与迄今为止开发的大多数践踏实验相比,我们将正石英和硅化石灰石人工制品放置在九层堆中,其中包括核心、薄片、不同的工具和大块。在这项研究中,我们专注于断裂并分析了断裂率和断裂类型。此外,我们将断裂试样的度量特征与为践踏破碎潜力提出的模型进行了对比。初步分析考虑了边缘损伤的数量、分布、位置、疤痕宽度和长度,以及伪工具的识别。
