尽管考古学家以前曾对石英和石英岩进行过使用磨损研究，但数量相对较少。此外，对石英岩制成的石材工具的使用磨损进行量化的努力相对较少。本文的目的是确定激光扫描共聚焦显微镜(LSCM)测量系统的有效性，以记录在两种不同接触材料(新鲜和干燥的鹿皮)上使用的实验性Mistassini石英岩刮刀的表面粗糙度或纹理。与以前使用激光扫描共聚焦显微镜对硅质岩、火石和黑铁矿的研究一样，这项探索性研究采用了一种数学算法，允许根据多个尺度上的比较来区分表面粗糙度。具体地说，我们使用相对面积(RELA)的测量和F-检验来区分未使用的石材工具表面，以及用于干燥和新鲜鹿皮的石英岩刮刀表面。我们的结果进一步证明了原材料变化对使用磨损形成的影响，并利用LSCM和RERA对其进行了记录。
Although previous use-wear studies involving quartz and quartzite have been undertaken by archaeologists, these are comparatively few in number. Moreover, there has been relatively little effort to quantify use-wear on stone tools made from quartzite. The purpose of this article is to determine the effectiveness of a measurement system, laser scanning confocal microscopy (LSCM), to document the surface roughness or texture of experimental Mistassini quartzite scrapers used on two different contact materials (fresh and dry deer hide). As in previous studies using LSCM on chert, flint, and obsidian, this exploratory study incorporates a mathematical algorithm that permits the discrimination of surface roughness based on comparisons at multiple scales. Specifically, we employ measures of relative area (RelA) coupled with the F-test to discriminate used from unused stone tool surfaces, as well as surfaces of quartzite scrapers used on dry and fresh deer hide. Our results further demonstrate the effect of raw material variation on use-wear formation and its documentation using LSCM and RelA.
